package tftpd-hpa 5.2-1ubuntu1 failed to install/upgrade: Unterprozess installiertes post-removal-Skript gab den Fehlerwert 1 zurück

[Christian Hintze]

the post-removal script contains lines, where it should delete certain files or folders. if they do not exist, uninstall will fail because the post-removal script returns errorcode 1. just a minor issue, nevertheless.

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks for reporting this bug. Indeed, it looks as though the postrm script does 'rmdir --ignore-fail-on-non-empty' but that still raises an error when the directory does not exist, so should be '|| true'.

/var/lib/dpkg/info/tftpd-hpa.postrm try deluser 'nobody'.
Change username in /etc/default/tftpd-hpa from 'nobody' to 'foo' and repeat install/purge.

This bug was raised against version 5.2-1ubuntu1 of the package, which has the following:

                                rmdir --ignore-fail-on-non-empty ${TFTP_DIRECTORY} > /dev/null 2>&1 || true

That's the only 'rmdir' in that file. So I'm pretty sure it's not that.

It could be the deluser problem that ignik points out. The maintainer script should not be trying to delete arbitrary users from the system who happen to be listed in /etc/default/tftpd-hpa!
