I've installed a program through the terminal, the program is Cuttlefish. Now I want to uninstall it and I can't find it in the software Center.
How can I do it?
You can uninstall the program through the terminal, very much like how you installed it.
sudo apt-get remove --purge <package-name>
So for cuttlefish you would run
sudo apt-get remove --purge cuttlefish
install synaptic package manager. Go to terminal by clrt+alt+T and type
sudo apt-get install synaptic
Form this you can install and remove packages in ubuntu without software center. Have a nice time.
sudo apt-get purge cuttlefish
Instead of uninstall, it removes anything related (most of the time).
