Its worth noting that there is a step missing here - you also need to run updatedb after installing mlocate and that isn't obvious. Setting up mlocate (0.26-2ubuntu3.1) ... update-alternatives: using /usr/bin/mlocate to provide /usr/bin/locate (locate) in auto mode (disco-amd64)root@impulse:/tmp# locate ubuntu.py locate: can not stat () `/var/lib/mlocate/mlocate.db': No such file or directory If mlocate were to be removed from the standard installation then we should improve this situation. -- Brian Murray -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
