Can I just change the name of the folder?
If I had an Ethernet cable plugged in I could use the package manager, redirect it to a non free repository.
I do not have at home internet. I would have thought someone here at faced this exact situation.
Looking at: Installing proprietary drivers at the last post, might be my problem is that I am not extracting the file to leave it with a .deb.
Which also brings back the other question, In the Pure OS, what is the top to bottom of how to describe the folder line down to either TMP or Downloads?
