I've no fuckin' idea. :lol: I tried it through the software manager, and with apt. The GUI prompts me for a bunch of unsigned shit, and apt wants to download like 40 package. I'm just trying to uninstall cups.Why on earth would you need to install something in order to uninstall something?
Synaptic is still in Ubuntu, unless you're running server, I do believe. My 10.10 still has it, and I use that instead of the Ubuntu Store thing.apt is probably bugging you for upgrades as well, download synaptic (the non-shit package manager) and try it with that instead
