I tried installing something to make a PlayStation 3 DualShock controller work on my Ubuntu 20.04 machine:
drubbels@drubbels:~$ sudo add-apt-repository ppa:falk-t-j/qtsixa
drubbels@drubbels:~$ sudo apt update
drubbels@drubbels:~$ sudo apt upgrade
drubbels@drubbels:~$ sudo apt install qtsixa
It did not make the controller work, unfortunately, so I chose to uninstall. I did not think to purge the qtsixa
package before removing the repository:
drubbels@drubbels:~$ sudo add-apt-repository --remove ppa:falk-t-j/qtsixa
I can no longer uninstall, or even find (using apt list --installed
and dpkg --get-selections
), qtsixa
now (re-adding the repository does not make it reappear).
Was it removed along with the ppa? Or does it now exist invisibly on my machine as some kind of unfindable 'phantom' package?
