One of my servers was originally running Ubuntu Server 18.04 (Bionic) and a very common task would be to substitute user, eg. su like this:



su someusername


Usually I would use tab completion to avoid typing the entire username. However, after upgrading to Ubuntu Server 19.04 this no longer auto completes when pressing tab. When I press tab right after typing su I get a list of files instead of usernames.



I have verified that I have bash-completion installed and I even tried:



source /etc/bash_completion


However, it didn't help.

    I don't know how to restore the original behavior, but just wanted to note that it seems to be part of a greater change that replaces the implementation of su provided by the login (shadow) package with one from util-linux - the latter provides its own completions file whereas the former apparently used a deprecated _su provided by the bash-completions package. For background, see util-linux: Please use login/passwd implementations provided by util-linux

    ... note that it apparently will complete usernames if you use one of the explicit options su -u, su --user or su - (to start a login shell for the target user)
