Hi all, as the section says: absolute beginner... I've been trying to use Ubuntu 10.10 with my MacBook 4,1. The OS runs all right, but I can't seem to contact any packages server. I've tried to install the Broadcom STA Wireless driver for the wireless hardware in the MacBook to no avail.
Trying to install a manually downloaded version of the driver: OS refuses the file as "unstrusted".
Trying to install from software center: OS cannot fetch files.
Both problems seem to be a staple since Google has lots about them, but nothing really helped. Is there no simple way? NOTE: I'm not behind a proxy.
