Hi hkilla,

First of all, make sure that you're downloading from the official FW site. Click on the blue link below & then on the Ubuntu button & you should be able to download the right installer: FrostWire.com - Official Website - Download Free P2P BitTorrent/Gnutella Client - No Subscriptions, Just Download and Install

There aren't many Linux users helping on this forum ATM. If you run into troubles with your install of FW then you might be better off asking at the FW forum - they may have more Linux users there
