when i try to upgade ubuntu it always says there is a missing package or it will say that there isnt enough room on my boot drive and i have a 1TB drive, oh and it would be kinda helpful if you could get firefox to not crash on me. it would be of great help thank you.
im not that much of an software expert (i know all my hardware) but im willing to listen how to fix it.
