I am running Ubuntu 12.4 64amd. I cant get easy tether to install regardless of which version I use (32 or 64bit.) I keep getting an error when I try to run it in the command line. It tells me it not a valid deb file. If I click it on the desktop the instal manager comes up but the install button is not highlighted for me to click to install it that way. Please help. I'll be using my phone as internet modem
