Package: cron
Version: 3.0pl1-154
Severity: normal
Dear Maintainer,
The postrm script in the current version of the cron package assumes the
presence of a dpkg-statoverride for /usr/bin/crontab, but no such statoverride
is present on my systems. As a result when I try to 'purge' the cron package
the process fails.
Recipe to reproduce the issue:
1) cd /root
2) mkdir foo
3) debootstrap --variant=minbase --include=logrotate,systemd-cron bookworm
4) chroot /root/foo /bin/bash
5) apt remove --purge cron
This results in the following output:
Reading package lists... Done
Building dependency tree... Done
The following packages will be REMOVED:
cron*
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
After this operation, 0 B of additional disk space will be used.

Control: severity -1 serious According to Debian Policy §6.6, "all postrm actions must only rely on essential packages and must gracefully skip any actions that require the package’s dependencies if those dependencies are unavailable."

Hi!
Although I've not tested nor checked the affected code, the fix done
to close this cannot possibly be correct, see below. :)

I think the description might be read incorrectly. The error is not
that the dpkg-statoverride program is missing, as that's not possible
(w/o force) being part of dpkg which is an Essential package. But that
a statoverride entry setup by some package is missing.

As can be seen here, the tool is executed and it runs, but it warns that
it cannot find the statoverride entry.

Adding a dependency on dpkg cannot have solved anything here.
Thanks,
