Once I get to step 3 on yours, terminal starts saying "Could not get lock /var/lib/dpkg/lock - open 11
Unable to lock the admin directory (/var/lib/dpkg/), is another process using it?
I tried logging off and logging back on, but gives me the same thing.
As I said, you need to type "sudo <whatever>" to run it as root (linux eqiv to admin)
