When I used yocto to build my first linux system and after 'bitbake imx-image-multimedia' was excuted, I faced the odd error:

ERROR: gnu-config-native-20190501+gitAUTOINC+b98424c249-r0 do_unpack: Unpack failure for URL: 'git://git.savannah.gnu.org/config.git'.

ERROR: Task (virtual:native:/home/admin/Linux/Yocto/fsl/sources/poky/meta/recipes-devtools/gnu-config/gnu-config_git.bb:do_unpack) failed with exit code '1'

Curious about the logfile, I opened /home/admin/Linux/Yocto/fsl/build/tmp/work/x86_64-linux/gnu-config-native/20190501+gitAUTOINC+b98424c249-r0/temp/log.do_unpack.73483 and I see:

What is 'ERROR: Unpack failure for URL: git://git.savannah.gnu.org/config.git'. No up to date source found: clone directory not available or not up to date: /home/admin/Linux/Yocto/fsl/downloads//git2/git.savannah.gnu.org.config.git; shallow clone not enabled means? What can I do to fix it? Thanks!

  • The command is 'bitbake [target]', I mistakenly entered ‘it‘ before it. – Xiuhua Yang May 29 '22 at 14:52
  • Seems the clone didn't work as either the remote repo is not accessible by your build machine... or some fetch issue and unpack is failing.. could you do explicit fetch with `bitbake -f -c gnu-config -vv` and see what's going on there. – SD. Jun 07 '22 at 17:37

See first if this is similar to this thread

Currently, for my Yocto builds (for nxp and other boards) I used to share a same "downloads" DL_DIR to avoid unnecessary fetch operations.

I tried to use an empty DL_DIR...and it worked fine.

After investigating, I found out there is something wrecked in the "git2" sub-directory of DL_DIR. I don't know what exactly.

So if you have a custom DL_DIR with a lot of stuff, try to rename your "git2" subdir as "git2.bak".

Check also if the // seen in /home/admin/Linux/Yocto/fsl/downloads//git2/git.savannah.gnu.org.config.git means an empty environment variable, meaning check if there should be an intermediate folder between downloads/ and /git2.

I've recently encountered this problem. I had an empty do_fetch function

do_fetch(){
  :
}

. Just by removing it, the git repo was cloned properly.

try normal clone with git clone git://git.savannah.gnu.org/config.git /home/admin/Linux/Yocto/fsl/downloads//git2/git.savannah.gnu.org.config.git

  • This is a terrible answer and should be removed. How was he supposed to try a normal clone when he clearly states he is using bitbake? Is he supposed to implement his own fetcher in Yocto? – Larry The Blackbird Aug 30 '23 at 14:18
