[Pkg-linaro-lava-devel] Bug#887622: lava-server: fails to purge: post-removal script subprocess returned error exit status 128

[Andreas Beckmann]

Package: lava-server
Version: 2018.1-2
Severity: important
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package failed to purge.
According to policy 7.2 you cannot rely on the depends being available
during purge, only the essential packages are available for sure.

Filing this as important because a.) it's a clear policy violation (to
not clean up at purge) b.) having a piuparts clean archive is a release
goal since lenny and c.) this package being piuparts buggy blocks
packages depending on it from being tested by piuparts (and thus
possibly the detection of more severe problems).

>From the attached log (scroll to the bottom...):

This was observed after a stretch -> buster upgrade.
