Comment 4 for bug 160862

Dear all,

I'm using the current updated Version of Ubuntu
I deleted an user wit admin-users. The an error message
appeared like "root group can not be deleteed..."
all Groups had been deleted from /etc/groups except the
the group of current login user, the deleted user and root.

Unfortunately I have no further details. But as I have seen
in the bug report list, this is a known, but not confirmed issue.

Maybe this helps.

Thank you all for you hard free work..
