I maybe have found something in system-tools-backend which could explain this weird bug.
system-tools-backends looks at the line number instead of the group name to see if a group have been deleted/added/modified. Just look at the set function in /usr/share/system-tools-backends-2.0/scripts/Users/Groups.pm I won't go into details but this behaviour works correctly only the first time. If you launch users-admin, delete a group and then create a new user (with a new group), system-tools-backends will try to delete another group and will try to rename several groups (which fail because the target group name already exists). /usr/share/system-tools-backends-2.0/scripts/Users/Users.pm seems to behave the same. I am not sure this is the cause of this bug, I still don't see in what conditions it could trigger this bug. -- Adding a user to a group modifies other users' groups and passwords https://bugs.launchpad.net/bugs/26338 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
