Bug#1027476: cron: postrm script fails because expected dpkg-statoverride is not present

Show all headers | View raw

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:

Editing /var/lib/dpkg/info/cron.postrm to remove the first section resolves the
issue.
