[KenWeiLL]

Public bug reported:

Removing authentication keys from Software & Updates is not working. It
asked for a password when trying to remove a key, then nothing happens.

Tried this on both Ubuntu (gnome) and Ubuntu-Mate and its not working on both distros or DE.
It however work from the terminal with "sudo apt-key del" without a problem.
Its just that it doesn't work from the GUI.
