Uninstall kubuntu-desktop from ubuntu 18.04
I've installed kubuntu desktop on ubuntu 18.04 with tasksel. How can I uninstall it?
Solution 1:
If you installed it via sudo apt-get install kubuntu-desktop you can uninstall it by
sudo apt-get remove kubuntu-desktop --autoremove
To be safe, run the reconfigure on your login manager.
sudo dpkg-reconfigure gdm3
After that, you might need to reboot your machine.
Solution 2:
Synaptic as mentioned by @N0rbert, (with completely remove option) was the only way to fully remove all traces of Kubuntu. Everything worked perfectly.
