Completion for umount behaves incorrectly

[John Runyon]

Completion for umount behaves incorrectly. It does not complete relative paths and does not escape characters as needed:

something\jrunyon@pc:/media$ ls
'something\jrunyon'
something\jrunyon@pc:/media$ umount <tab> [-> umount /]
something\jrunyon@pc:/media$ umount s<tab> [-> umount s]
something\jrunyon@pc:/media$ umount /m<tab> [-> umount /media/something\jrunyon/778362E66C6546B5]
umount: /media/somethingjrunyon/778362E66C6546B5: No such file or directory

Ubuntu 18.10 is end of life and is not supported anymore and also a security risk to keep using.

Please download a supported version from: https://ubuntu.com/#download

Problem also exists on 18.04.

Why don't you try it and see if you can replicate instead of closing?
