As explained elsewhere, though I have Mint 6 running fine on my laptop, I have Mint 4 on my desktop pc. I have two downloaded files meant to enable me to use my Vodafone mobile Broadband modem with the equivalent Ubuntu, one is a .deb file that wants some python files I haven't got, the other is a run file which seems to uncompress and then exclaims 'run as root!' and doesn't install. I did set up a root account, if that's what it's called, but I have no idea how to 'run as root'. Can someone explain. Best of all by using my specific example: say I have this Vodafone driver/application saved on my desktop. I imagine I have to type something in Terminal but that's as far as I understand.
