[Adduser-devel] Bug#351681: adduser tries to re-use existing GID

[Friedrich Delgado Friedrichs]

Package: adduser
Version: 3.81
Severity: important


I'm sorry if I report this bug against the wrong package.

I've tried hard to find the reason for the error and found out that
the postinstall scripts for the three packages in question all call
adduser in the same way, which fails, so I decided that adduser was
the best package to report this bug against.

Installing the packages chipcard-tools and libchipcard2-tools and
upgrade of oidentd fails with the following error messages:

--->8----

The group with ID 118 is the "postdrop" group, owned (and created) by
the postfix package.

The format of my /etc/group file looks completely correct, the only
manual edits in that file have been adding users to groups, no
rearranging, creation or deletion of groups.

Kind regards
