I didn't know what was the best way to install stuff
I found commands, websites, software manager-it's hard to know what to get from where. Example, software manager only had thunderbird 3.something, where as I google and found out how to get 9. Do I have so stick to only what's available thru software manager?
And what do I do now? My update manager still comes up with a big old error when I open it because files are missing. Is there a repository that actually works right?
