Little fix in line 23.
As a result of this, after updating to Git 2.35.2, line 23 fails with the following error for each AUR package directory (when the script is run as root with the pacman hook):
fatal: unsafe repository ('/home/xfzv/.cache/paru/clone/aur-pkg-name' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /home/xfzv/.cache/paru/clone/aur-pkg-name
Adding an exception as suggested (for root git config) works as expected but I'd like to avoid doing this if possible, not to mention it should be done for each AUR package. It would be a pain to maintain in the long run. Edit: Git 2.35.3 now includes safe.directory="*"
to completely disable this security check.
I guess there are other solutions such as chown
ing ~/.cache/paru/clone/
to root:root
but it's obviously a terrible idea. Another one I come up with is to run the git ls-files
command as regular user with:
su $(id -nu 1000) -c "rm -f $(git ls-files --others [...])"
but for some reasons I keep getting the same error with the full rm -f $(git ls-files ..)
command.
I also tried modifying the pacman hook so that the script is run as regular user:
[Action]
Exec = /bin/su xfzv -c "/home/xfzv/.local/scripts/paccache.sh"
But I'm getting an error:
==> Privilege escalation required
==> ERROR: Unable to escalate privileges using sudo
error: command failed to execute correctly
Hopefully you can come with a workaround!
Thanks in advance for your time. 🙇
I've just tried again with your last changes and it works just fine. Thank you very much!
