Package: mandos-client
Version: 1.8.16-1
Severity: serious
mandos-client's postrm script can fail on purge with no obvious error
message. dpkg reports that it exited with error code 128 but it's not
clear why. I can reproduce this in a bookworm/amd64 or unstable/amd64
build chroot by running:
apt install -y mandos-client linux-image-amd64
apt purge -y mandos-client
Ben.
Dear Maintainer,
I just tried to get some more info about this.
By adding a "set -x" at the top of the postrm script I could watch
which commands get executed [2].
At the end it looks like the output of the earlier update-initramfs
gets into stdin of the db_purge call later.
At least when redirecting stdout to stderr [1] of the update-initramfs call
the removal completes without error.
Kind regards,
Bernhard
