well, as you can see i am very noob at linux. the question is that im downloading the packages over the internet, for example the java package and when i try to open it, my linux (ubuntu) asks me if i want to open it with the extract program or the console, i try both and i can't install them, with the extract one, the program can't open the file and with the console, the console appears for 1/, of second and the closes.
I tried to download another kind of programs and in them comes files like *.sh and when i try to run it i can't do it. sorry to disturbe, but maybe someone can help me.
