I think this is OK; dpkg is just saying 'I installed this directory but I can't remove it because it contains stuff I did not create'.

That said, this package completely fails to remove the accounts it creates which is a bug. ** Summary changed: - Unable to remove all keystone related files after purging/removing the package + keystone does not remove user accounts on purge -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1078633 Title: keystone does not remove user accounts on purge To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keystone/+bug/1078633/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
