I have had no help from my IT guy and he's disappeared. I am so frustrated with this LINUX it's not funny.

Cannot open downloads . When I check on sites for help it just so much gobbledygook and tech jargon.
Does anyone have a simple solution to open a download without hours writing to system like...
deb http://.dl.sourceforge.net/project/jedit /deb jEdit - Browse Files at SourceForge.net /
Then, just run apt-get update, followed by apt-get install jedit.
WTF !...why can't this load automaticly or at least say what the hell you need to open it.
Furinsence....here's what I get trying to open a R129 2000yr > download from Mercedes.

Anyone with a SIMPLE solution apart from going back to Windows.?
