Bug#1119941: grub2: /usr/share/doc/grub-common leftover/messed-up

[Christoph Anton Mitterer]

Source: grub2
Version: 2.14~git20250718.0e36779-2
Severity: normal

Hey.

Getting rid of grub-common seems to have left over some files:
Purging configuration files for grub-common (2.14~git20250718.0e36779-2) ...
dpkg: warning: while removing grub-common, directory '/usr/share/doc/grub-common' not empty so not removed

# tree /usr/share/doc/grub-common
/usr/share/doc/grub-common

├── AUTHORS

├── NEWS.gz

├── THANKS
├── TODO

└── copyright

None of them is registered anymore to any package:
# dpkg -S /usr/share/doc/grub-common
dpkg-query: no path found matching pattern /usr/share/doc/grub-common

though it seems they're still "used":
# ls -ald /usr/share/doc/grub*
lrwxrwxrwx 1 root root  11 May 18  2011 /usr/share/doc/grub2-common -> grub-common
drwxr-xr-x 1 root root 184 Nov  2 16:42 /usr/share/doc/grub-common
lrwxrwxrwx 1 root root  11 Jun 19  2021 /usr/share/doc/grub-efi -> grub-common
lrwxrwxrwx 1 root root  18 Sep 18  2023 /usr/share/doc/grub-efi-amd64 -> grub-efi-amd64-bin
drwxr-xr-x 1 root root 108 Nov  2 16:42 /usr/share/doc/grub-efi-amd64-bin
lrwxrwxrwx 1 root root  11 Jul 10  2024 /usr/share/doc/grub-efi-amd64-unsigned -> grub-common
lrwxrwxrwx 1 root root  11 May 18  2011 /usr/share/doc/grub-pc-bin -> grub-common

The current grub2-common package should have all these files in
/usr/share/doc/grub2-common, see:
# dpkg -L grub2-common | grep doc
/usr/share/doc
/usr/share/doc/grub2-common
/usr/share/doc/grub2-common/AUTHORS
/usr/share/doc/grub2-common/NEWS.Debian.gz
/usr/share/doc/grub2-common/NEWS.gz
/usr/share/doc/grub2-common/README
/usr/share/doc/grub2-common/THANKS
/usr/share/doc/grub2-common/TODO
/usr/share/doc/grub2-common/changelog.Debian.gz
/usr/share/doc/grub2-common/changelog.gz
/usr/share/doc/grub2-common/copyright
/usr/share/doc/grub2-common/examples
/usr/share/doc/grub2-common/examples/grub.cfg


Before the upgrade, i.e. still on version 2.12-9, this looked like:
# dpkg -S /usr/share/doc/grub-common/*
grub-common: /usr/share/doc/grub-common/AUTHORS
grub-common: /usr/share/doc/grub-common/changelog.Debian.gz
grub-common: /usr/share/doc/grub-common/changelog.gz
grub-common: /usr/share/doc/grub-common/copyright
grub-common: /usr/share/doc/grub-common/examples
grub-common: /usr/share/doc/grub-common/NEWS.Debian.gz
grub-common: /usr/share/doc/grub-common/NEWS.gz
grub-common: /usr/share/doc/grub-common/README
grub-common: /usr/share/doc/grub-common/THANKS
grub-common: /usr/share/doc/grub-common/TODO


So there seems a bit of a messup.


Cheers,
Chris.
