Comment 4 for bug 1928414

Ok, I am using ubuntu studio, thus I had discodos even if I not use it.

I was with full broken apt and thus I could not even purge discodos

Then I used

sudo dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge discodos

If it's says it's need superuser even if you are using sudo
Sudo su
It will open the superuser terminal, use
sudo dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge dicodos

And then close the terminal, for safety reasons
