I'm using command-not-found 0.2.3, but it also occurs with all the earlier version I've seen. Anything that triggers c-n-f will cause that to be output, whether it finds something that has a matching package or not.
After looking, I just noticed that somehow my user has a gid of 500, but there is no group with that id - I have no idea what would have caused that. -- warning emitted about not finding group name https://launchpad.net/bugs/95794 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
