Cannot purge biond glance-common (train)

[Eliezer Croitoru]

when I am trying to purge glance-comon I am receiving and error.
The question about this issue is at:

Output of:

     8 deluser --system --quiet --backup-to /var/lib glance
     9 fi
    10 if (which delgroup && getent group glance) > /dev/null 2>&1; then
    11 delgroup --system --quiet glance
    12 fi

+ getent passwd glance
glance:x:64062:64062::/var/lib/glance:/bin/false
+ getent group glance
glance:x:64062:
+ set +x

Shows that the glance user and group id are not system(ie under 1000).
Due to this the deluser and delgroup with the "--system" fails.

I don't know if the UID and GID are wrong or if the "--system" flag is wrong.
Either way it need to be fixed.

Thanks,

Eliezer, Thank you for reporting this bug and making Ubuntu better. I've confirmed this is a bug and triaged it as medium as there is a known work-around.

[Corey Bryant (corey.bryant)]

I think this bug exists since queens when glance-common.postinst was updated to use reserved uid/gid for glance user/group.

This bug was fixed in the package glance - 2:21.0.0~b2~git2020073013.cfbe5f76-0ubuntu2

---------------
glance (2:21.0.0~b2~git2020073013.cfbe5f76-0ubuntu2) groovy; urgency=medium

  * d/glance-common.postrm: Drop --system from deluser/delgroup calls. This
    aligns with the glance-common.postinst script reserved glance uid/gid
    (LP: #1889846).

Since I am working on bionic and it's a tiny change, Can you backport the fix to bionic?
