3 1.123 jmc This file (UPDATING) is intended to be a brief reference to recent
4 1.123 jmc changes that might cause problems in the build process, and a guide for
5 1.123 jmc what to do if something doesn't work.
6 1.1 abs
7 1.123 jmc For a more detailed description of the recommended way to build NetBSD
8 1.123 jmc using build.sh, see the BUILDING file.
9 1.123 jmc
10 1.123 jmc Note that much of the advice in this UPDATING file was written before
11 1.123 jmc build.sh existed. Nevertheless, the advice here may be useful for
12 1.123 jmc working around specific problems with build.sh.

23 1.363 martin Changes around the integration of the zstd compression
24 1.363 martin library may require manual deletion of some object directories
25 1.366 riastrad if you update from a build from a few days ago:
26 1.366 riastrad rm -rf DESTDIR/usr/lib/*/libarchive*
27 1.366 riastrad rm -rf DESTDIR/usr/lib/*/libmagic*
28 1.366 riastrad rm -rf DESTDIR/usr/lib/*/libzstd*
29 1.366 riastrad rm -rf DESTDIR/usr/lib/libarchive*
30 1.366 riastrad rm -rf DESTDIR/usr/lib/libmagic*
31 1.366 riastrad rm -rf DESTDIR/usr/lib/libzstd*
32 1.366 riastrad rm -rf OBJDIR/compat/*/*/external/bsd/file/

42 1.360 wiz Building -current when running on amd64 from about 20240924
43 1.360 wiz to about 20240926 will not work due to a "malloc_np.h"
44 1.360 wiz error. Please downgrade to a version from 20240924 or older,
45 1.360 wiz or upgrade to a newer version e.g. using a binary release from
46 1.360 wiz the NetBSD build servers.
47 1.360 wiz
48 1.358 martin 20240923:
49 1.358 martin Update builds will require cleaning the object directories for
50 1.359 martin jemalloc (like: "rm -rf $OBJ/external/bsd/jemalloc*") and the
51 1.359 martin libc dependency files (like: "rm $OBJ/lib/libc/jemalloc.*").
52 1.359 martin On architectures with COMPAT libs, those also have to be cleaned,
53 1.359 martin e.g. on sparc64: "rm -rf $OBJ/compat/sparc64/sparc/external/bsd/jemalloc*"
54 1.359 martin and "rm $OBJ/compat/sparc64/sparc/lib/libc/jemalloc.*".
55 1.358 martin
56 1.357 christos 20240817:
57 1.357 christos Update builds will require cleaning in src/external/historical/nawk/bin
58 1.357 christos in order to remove the awk binary since now there is a subdirectory
59 1.357 christos called awk.
60 1.358 martin
61 1.355 martin 20240812:
62 1.355 martin Update builds will require removing the tools objdir for gdb
63 1.355 martin if building with MKCROSSGDB=yes. All architectures use gdb.old
64 1.355 martin now.
65 1.356 riastrad
66 1.354 martin 20240630:
67 1.353 martin Update builds will require removing the tools objdir for binutils
68 1.353 martin (as most architectures should use binutils.old now).
69 1.353 martin
70 1.352 kre 20240610:
71 1.352 kre Update builds are likely to require removing the objdir for
72 1.352 kre distrib/<arch>/cdroms - or at least references to libarchive
73 1.352 kre from within there after the recent libarchive update.
74 1.352 kre
75 1.350 riastrad 20240504:
76 1.350 riastrad Update builds on x86 require making the `cleandir' target in
77 1.350 riastrad lib/libm, or deleting the objdir for lib/libm.
78 1.350 riastrad
79 1.349 maya 20240423:
80 1.349 maya Update builds with x11 may fail after switching to Mesa 21.
81 1.349 maya
82 1.346 riastrad 20240410:
83 1.346 riastrad Update builds may require manually deleting
84 1.346 riastrad $DESTDIR/var/run/named (and, potentially,
85 1.346 riastrad $DESTDIR/var/run/lwresd) in order to avoid checkflist failure.
86 1.346 riastrad
87 1.347 nia 20240409:
88 1.347 nia 32-bit compatibility libraries were moved into the base32
89 1.347 nia and debug32 sets. HTML man pages were moved into the manhtml set.
90 1.347 nia
91 1.343 riastrad 20230828:
92 1.343 riastrad If:
93 1.343 riastrad - you updated to current and ran postinstall between 20230826
94 1.343 riastrad and 20230828 inclusive, and
95 1.343 riastrad - you are not using anything outside the base system to
96 1.343 riastrad populate /etc/openssl/certs (e.g., manually adding
97 1.343 riastrad certificates or using ca-certificates or mozilla-rootcerts or
98 1.343 riastrad mozilla-rootcerts-openssl from pkgsrc),
99 1.343 riastrad delete /etc/openssl/certs and rerun postinstall or just
100 1.343 riastrad `certctl rehash'.
101 1.343 riastrad
102 1.343 riastrad Otherwise, certctl(8) will think someone else has left
103 1.343 riastrad /etc/openssl/certs in the way and will avoid clobbering it on
104 1.343 riastrad upgrade from older NetBSD.
105 1.343 riastrad
106 1.341 lukem 20230718:
107 1.341 lukem build.sh will use mk.conf in the same directory as build.sh instead
108 1.341 lukem of /etc/mk.conf, unless MAKECONF is already defined in the environment.
109 1.341 lukem
110 1.342 martin 20230714:
111 1.342 martin Import of gcc 10.5 requires a clean build of at least tools/gcc
112 1.342 martin and external/gpl3/gcc* object directories. An update build
113 1.342 martin without cleaning will result in obscure failures in rare corner
114 1.342 martin cases.
115 1.342 martin
116 1.339 martin 20230604:
117 1.339 martin Building native kernels with the installed make(1) instead of
118 1.339 martin the $TOOLDIR/bin/nbmake-${arch} wrapper will fail if userland
119 1.339 martin has not been updated. Note that this is an unsupported build
120 1.339 martin configuration (but usually works if userland is -current enough).
121 1.338 lukem
122 1.338 lukem 20230523:
123 1.338 lukem ctfmerge was fixed as macOS host tool. This may require a clean tools
124 1.338 lukem rebuild to detect the update to tools/compat/configure.
125 1.338 lukem
126 1.340 martin 20230515:
127 1.340 martin New openssl build requires removal of the crypto/external/bsd/openssl
128 1.345 andvar and tests/crypto/libcrypto subdirectories in the ${OBJDIR} hierarchy.
129 1.340 martin Otherwise test results may be wrong due to wrong "golden" output
130 1.340 martin files being installed.
131 1.340 martin
132 1.337 mrg 20230322:
133 1.337 mrg Fixes for moved /lib/libisns* mean that builds will complain about
134 1.337 mrg ./usr/lib/libisns* being missing until src/lib/libisns is forced
135 1.337 mrg to (re)install the files, including the symlinks. The simplest
136 1.337 mrg way is to clean this subdir before building.
137 1.337 mrg
138 1.336 martin 20230112:
139 1.336 martin New binutils require an updated ld.elf_so. If you are doing
140 1.336 martin (unsupported) in-place self builds (with the -E flag to build.sh),
141 1.336 martin make sure to have installed latest ld.elf_so before you rebuild
142 1.336 martin userland.
143 1.336 martin
144 1.335 chs 20221116:
145 1.335 chs The addition to NetBSD's version of UFS2 of support for extended
146 1.335 chs attributes broke backward compatibility with previous releases
147 1.335 chs of NetBSD, so UFS2 has been restored to being compatible with
148 1.335 chs previous NetBSD releases by disabling extended attributes.
149 1.335 chs (Note that ACLs are implemented as extended attributes, so
150 1.335 chs this changes disables ACLs as well.)
151 1.335 chs
152 1.335 chs Support for UFS2 with extended attributes is now available in a new
153 1.335 chs UFS variant called UFS2ea. If you have created extended attributes
154 1.335 chs in an original UFS2 file system then "fsck -p" will now fail due to
155 1.335 chs the unexpected presence of extended attributes and "fsck -y" will
156 1.335 chs remove all extended attributes. If you wish to preserve extended
157 1.335 chs attributes rather than delete them, there is a utility to convert
158 1.335 chs a UFS2 file system to UFS2ea and leave extended attributes in place,
159 1.335 chs but this should be used with caution since it will preserve any
160 1.335 chs extended attributes that have been corrupted by the backward
161 1.335 chs incompatibility too.
162 1.335 chs
163 1.335 chs If you wish to use a UFS2ea file system as your root file system,
164 1.335 chs then you will need to update your boot loader to a version that
165 1.335 chs supports UFS2ea.
166 1.335 chs
167 1.335 chs For more information, see:

169 1.335 chs
170 1.334 mrg 20221111:
171 1.334 mrg The new libdrm import worsened the conflict issues for the
172 1.334 mrg kdump/ktruss ioctl, and i915 now conflicts with base, and has
173 1.334 mrg been turned off. This will cause update build issues like:
174 1.334 mrg
175 1.334 mrg kdump-ioctl.c:12175:143: error: 'DRM_IOCTL_I915_DESTROY_HEAP'
176 1.334 mrg undeclared here (not in a function);
177 1.334 mrg did you mean 'DRM_IOCTL_MODE_DESTROY_DUMB'?
178 1.334 mrg
179 1.334 mrg You'll need to clean usr.bin/ktruss, usr.bin/kdump, and rescue.
180 1.334 mrg
181 1.331 riastrad 20220921:
182 1.331 riastrad Since the kernel version was bumped to 9.99.100, the bootloader
183 1.333 riastrad must be updated on x86 or EFI boot platforms in order to load
184 1.333 riastrad modules from boot.cfg(5) or interactively at the bootloader
185 1.333 riastrad prompt.
186 1.333 riastrad
187 1.333 riastrad The kernel can still load modules at runtime, with modload(8)
188 1.333 riastrad or modules.conf(5), with no bootloader update. This will not
189 1.333 riastrad affect release branches because it only applies to patch
190 1.333 riastrad numbers >=100.
191 1.333 riastrad
192 1.333 riastrad On x86 (i386 or amd64) with BIOS boot, this requires copying a
193 1.333 riastrad new /usr/mdec/boot to /boot. You can build this in the destdir
194 1.333 riastrad by running `$TOOLDIR/bin/nbmake-$ARCH dependall install' in
195 1.333 riastrad sys/arch/i386/stand.
196 1.333 riastrad
197 1.333 riastrad On platforms with EFI boot (including x86 with EFI boot), this
198 1.333 riastrad requires copying a new /usr/mdec/boot*.efi to the EFI/BOOT/
199 1.333 riastrad directory on the EFI system partition. The boot*.efi file is:
200 1.333 riastrad
201 1.333 riastrad aarch64 bootaa64.efi
202 1.333 riastrad amd64 bootx64.efi
203 1.333 riastrad arm bootarm.efi (32-bit arm)
204 1.333 riastrad i386 bootx32.efi
205 1.333 riastrad
206 1.333 riastrad You can build this in the destdir by running
207 1.333 riastrad `$TOOLDIR/bin/nbmake-$ARCH dependall install' in
208 1.333 riastrad sys/stand/efiboot/boot*.
209 1.331 riastrad
210 1.330 lukem 20220821:
211 1.330 lukem Support for building extsrc/ has been deprecated.
212 1.330 lukem EXTSRCSRCDIR and MKEXTSRC have been deprecated.
213 1.330 lukem
214 1.329 mrg 20220714:
215 1.329 mrg Updates to xorg-server and associated drivers may cause builds to
216 1.329 mrg fail. Cleaning both DESTDIR and the xorg build tree may be needed.
217 1.329 mrg
218 1.328 martin 20220628:
219 1.328 martin Changes in the build of src/games/robots require a clean build
220 1.328 martin of that program.
221 1.328 martin
222 1.324 martin 20211116:
223 1.324 martin Changes in the xorg build require clean obj dirs for external/mit/xorg
224 1.325 martin (or a full clean/non-update build).
225 1.324 martin
226 1.323 nia 20211112:
227 1.323 nia Device tree sources were updated for evbarm. Some device nodes
228 1.323 nia (in particular, ld(4) devices on the ROCKPro64) will be renumbered.
229 1.323 nia
230 1.322 martin 20211014:
231 1.323 nia MKPIE default for aarch64 has changed, a clean build is required.
232 1.322 martin
233 1.321 christos 20210917:
234 1.321 christos Changed MNT_ACLS to default to POSIX1e ACLs instead of NFSv4
235 1.321 christos ACLs, to be compatible with FreeBSD. If you are using NFSv4 ACLs
236 1.321 christos and have "acls" in /etc/fstab you'll need to change it to "nfs4acls".
237 1.321 christos
238 1.319 mrg 20210711:
239 1.319 mrg Updated GMP sources may require cleaning in tools/gmp and/or in
240 1.319 mrg external/lgpl3/gmp/lib, particularly if GCC itself does not build.
241 1.319 mrg
242 1.318 mrg 20210417:
243 1.318 mrg GCC 10 was enabled for several platforms. If builds fail in either
244 1.351 gutterid tools/gcc or external/gpl3/gcc, first try cleaning those objects and
245 1.318 mrg removing the $DESTDIR/usr/include/g++ subdirectory.
246 1.318 mrg
247 1.316 mrg 20201016:
248 1.316 mrg MIPS kernel modules have been disabled until they work. This will
249 1.316 mrg turn up in extra files in the DESTDIR, which should be cleaned.
250 1.316 mrg
251 1.315 mrg 20200925:
252 1.315 mrg GNU MPC and MPFR have been updated. At least MPFR needs cleaning
253 1.315 mrg in both the tools and external dirs.
254 1.315 mrg
255 1.314 mrg 20200912:
256 1.314 mrg GCC 9 has arrived for Arm and x86 platforms, and will be coming
257 1.314 mrg for several more, as will binutils 2.34. Clean as required.
258 1.314 mrg
259 1.313 mrg 20200907:
260 1.313 mrg GCC 9 is coming, and binutils has been updated for MIPS. This
261 1.313 mrg probably requires cleaning the tools/binutils.
262 1.313 mrg
263 1.311 mrg 20200811:
264 1.312 mrg GCC updates may require cleaning the objdir. This may occur
265 1.312 mrg due to GCC 7.5 update, GCC 8.4 move to gcc.old, or the upcoming
266 1.312 mrg GCC 9 upgrade.
267 1.311 mrg
268 1.309 christos 20200614:
269 1.310 christos blacklist* has been renamed to blocklist*. postinstall(8)
270 1.332 gutterid should handle the migration.
271 1.309 christos
272 1.308 christos 20200601:
273 1.308 christos Due to a mistake in LIBISPRIVATE handling, .so libraries were
274 1.308 christos created in the build directories and need cleaning.
275 1.308 christos
276 1.307 mrg 20200311:
277 1.307 mrg GCC 8 ports will need cleaning in src/tools/gcc and
278 1.307 mrg src/external/gpl3/gcc due to GCC 8.4 update.
279 1.307 mrg
280 1.306 christos 20191118:
281 1.306 christos More architectures were switched to gcc8:
282 1.306 christos i386, ia64 powerpc64, sparc, sparc64, arm
283 1.306 christos The same comments as in 20191022 apply.
284 1.306 christos
285 1.305 martin 20191112:
286 1.305 martin The LLVM update requires a clean rebuild for all architectures using
287 1.305 martin LLVM during the tools build phase (i386, amd64, aarch64).
288 1.305 martin
289 1.304 martin 20191022:
290 1.304 martin Ports amd64 and aarch64 switched to GCC 8.3 by default.
291 1.304 martin In-place ("expert mode", build.sh -E) builds are not supported
292 1.304 martin when going from a GCC 7 userland to GCC 8. Do a regular
293 1.304 martin build to a different DESTDIR (or preferably: build.sh -U) at least
294 1.306 christos once and install sets, or download comp.{tar.xz,tgz} from the
295 1.304 martin daily builds and install that before doing the next in-place build.
296 1.304 martin
297 1.303 mrg 20191001:
298 1.303 mrg GCC 8.3 was imported. Builds of src/tools/gcc may fail if
299 1.303 mrg old builds with GCC 7 output now uses GCC 8. Clean this
300 1.303 mrg directory, and also clean src/external/gpl3/gcc.
301 1.303 mrg
302 1.302 riastrad 20190903:
303 1.306 christos Files with names that coincide with existing files' names on
304 1.302 riastrad case-insensitive file systems were inadvertently committed, for
305 1.302 riastrad radeon GPU firmware. We cannot mark these as obsolete for
306 1.302 riastrad postinstall to fix, so if you updated src since 2019-08-26, and
307 1.302 riastrad ran build.sh distribution or ran build.sh release, you must
308 1.302 riastrad manually delete the following files in your DESTDIR (which is
309 1.302 riastrad usually $OBJDIR/destir.$ARCH), or from / if you have installed

383 1.301 martin The uefi bootloader has gained tftp support and needs a clean
384 1.301 martin build. If you do update builds, manually clean its object
385 1.301 martin directory by something like:
386 1.301 martin cd sys/arch/i386/stand/efiboot && make clean
387 1.301 martin
388 1.300 martin 20190723:
389 1.344 gutterid The jemalloc allocator in libc is now built without extended
390 1.300 martin debugging (for performance reasons). In update builds make sure
391 1.326 andvar to rebuild it completely, by removing all affected object files,
392 1.300 martin including compat builds, something like:
393 1.300 martin cd /usr/obj && find . -type d -name jemalloc|xargs rm -rf
394 1.300 martin
395 1.299 mrg 20190207:
396 1.299 mrg GCC 7 switched for many ports. Update builds are likely to fail.
397 1.299 mrg
398 1.1 abs Hints for a more successful build:
399 1.1 abs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
400 1.123 jmc Use build.sh, but do not use its "expert mode":
401 1.132 jmmv This will automatically build the tools in the
402 1.123 jmc correct order, and it will keep the tools and the
403 1.123 jmc new build products from interfering with the running
404 1.123 jmc system. This will allow you to ignore most of the
405 1.123 jmc other advice in this file.
406 1.2 mrg Build a new kernel first:
407 1.2 mrg This makes sure that any new system calls or features
408 1.2 mrg expected by the new userland will be present. This
409 1.2 mrg helps to avoid critical errors when upgrading.
410 1.1 abs Use object directories:
411 1.1 abs This helps to keep stale object
412 1.1 abs files from polluting the build if a Makefile "forgets"
413 1.1 abs about one. It also makes it easier to clean up after
414 1.1 abs a build. It's also necessary if you want to use the
415 1.1 abs same source tree for multiple machines.
416 1.123 jmc To use object directories with build.sh:
417 1.123 jmc a) invoke build.sh with the "-M" or "-O" options.
418 1.123 jmc To use object directories without using build.sh:
419 1.1 abs a) cd /usr/src ; make cleandir
420 1.2 mrg b) Add "OBJMACHINE=yes" to /etc/mk.conf
421 1.2 mrg c) Add "MKOBJDIRS=yes" to /etc/mk.conf
422 1.1 abs d) cd /usr/src ; make build
423 1.2 mrg Note that running "make obj" in a directory will create
424 1.2 mrg in obj.$MACHINE directory.
425 1.1 abs Build to a DESTDIR:
426 1.123 jmc This helps to keep old installed files (especially libraries)
427 1.123 jmc from interfering with the new build.
428 1.123 jmc To build to a DESTDIR with build.sh, use the "-D" option.
429 1.123 jmc To build to a DESTDIR without using build.sh, set the DESTDIR
430 1.123 jmc environment variable before running make build. It should be
431 1.123 jmc set to the pathname of an initially empty directory.
432 1.123 jmc Problems: if you do not use build.sh, you might need to
433 1.123 jmc update critical utilities without using DESTDIR since
434 1.123 jmc nothing is executed from what is installed in DESTDIR.
435 1.123 jmc (See critical utils, below.)
436 1.1 abs Build often:
437 1.1 abs This keeps critical utilities current enough to not choke
438 1.1 abs on any other part of the source tree that depends on up to
439 1.123 jmc date functionality. If you use build.sh, you should not have
440 1.123 jmc this problem.

442 1.1 abs What to do if things don't work:
443 1.1 abs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
444 1.230 tls When things don't work there are usually a few things that commonly
445 1.1 abs should be done.
446 1.1 abs 1) make includes
447 1.1 abs This should be done automatically by make build.
448 1.1 abs 2) cd share/mk && make install
449 1.1 abs Again, automatically done by make build.
450 1.1 abs
451 1.1 abs Failsafe rebuild of a small part of the tree:
452 1.1 abs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
453 1.1 abs To make sure you rebuild something correctly you want to do
454 1.1 abs something like the following:
455 1.1 abs 1) Make sure the includes and .mk files are up to date.
456 1.1 abs 2) Make sure any program used to build the particular
457 1.1 abs utility is up to date. (yacc, lex, etc...)
458 1.1 abs 3) cd ...path/to/util...
459 1.1 abs make cleandir
460 1.1 abs rm ...all obj directories...
461 1.1 abs make cleandir # yes, again
462 1.1 abs make obj
463 1.1 abs make depend && make
464 1.1 abs
465 1.1 abs Failsafe rebuild of the entire tree:
466 1.1 abs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
467 1.1 abs If you really want to make sure the source tree is clean and
468 1.2 mrg ready for a build try the following. Note that sourcing /etc/mk.conf
469 1.2 mrg (a make(1) Makefile) in this manner is not right, and will not work
470 1.2 mrg for anyone who uses any make(1) features in /etc/mk.conf.

504 1.34 simonb Other problems and possible solutions:
505 1.1 abs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
506 1.1 abs Symptom:Complaints involving a Makefile.
507 1.17 erh Fix: Rebuild usr.bin/make:
508 1.17 erh cd usr.bin/make && make && make install
509 1.111 simonb Or, a failsafe method if that doesn't work:
510 1.348 rillig cd usr.bin/make && cc -DMAKE_NATIVE *.c -I. -o make \
511 1.348 rillig && install make /usr/bin
512 1.17 erh
513 1.1 abs Fix: Make sure .mk files are up to date.
514 1.1 abs cd share/mk && make install
515 1.2 mrg
516 1.2 mrg Symptom:Kernel `config' fails to configure any kernel, including GENERIC.
517 1.142 drochner Fix: Rebuild usr.bin/config
518 1.1 abs
519 1.4 itojun Symptom:Obsolete intermediate files are used during compilation
520 1.4 itojun Fix: Try the following sequence of commands in the directory in question.
521 1.4 itojun make cleandir; rm `make print-objdir`; make cleandir; make obj
522 1.4 itojun (If you built the tree without "make obj" in the past, obsolete files
523 1.4 itojun may remain. The command tries to clean everything up)
524 1.5 wiz
525 1.207 mbalmer Symptom:.../sysinst/run.c:xx: warning: initialization from incompatible
526 1.207 mbalmer pointer type
527 1.5 wiz Fix: Rebuild and install usr.bin/menuc
528 1.12 itojun
529 1.12 itojun Symptom:mklocale not found during build in share/locale/ctype
530 1.12 itojun Fix: Build and install usr.bin/mklocale
531 1.13 dogcow
532 1.86 kleink Symptom:undefined reference to `__assert13' or `__unsetenv13'
533 1.13 dogcow Fix: Rebuild and install lib/libc
534 1.13 dogcow
535 1.142 drochner Symptom:usr.bin/config fails to build.
536 1.19 cgd Fix: Try building with -DMAKE_BOOTSTRAP added to CFLAGS in Makefile.
537 1.13 dogcow
538 1.19 cgd Symptom:undefined reference to `getprogname' or `setprogname'
539 1.19 cgd Fix: Rebuild and install lib/libc
540 1.24 abs
541 1.223 joerg Symptom:Update build fails in src/tools/gcc complaining that a variable
542 1.223 joerg (e.g. CPPFLAGS) has changed since the previous run.
543 1.223 joerg Fix: Run "nbmake-${ARCH} clean" in src/tools/gcc or do a clean build.
544 1.257 apb
545 1.257 apb Symptom:cvs [update aborted]: cannot open directory /cvsroot/src/...:
546 1.257 apb No such file or directory.
547 1.257 apb Cause: If a directory is created by mistake, then it is sometimes
548 1.257 apb deleted from the CVS repository using administrative commands
549 1.257 apb that bypass the normal cvs access controls. If your cvs working tree
550 1.257 apb contains references to a directory that has been deleted on the
551 1.257 apb server in this way, then "cvs update" reports this error.
552 1.257 apb Fix: Recursively delete the affected directory from your working tree
553 1.257 apb and try the update again.
