The software updater wants to download and install 305 mb of stuff. Being new to Ubuntu I don't know if I should let it do this. I'm a little bit afraid because I just spent about a month trying to get Ubuntu working at all and I don't want to screw anything up. Particularly, when I tried to update to kernel 3.5.0-25 my keyboard and mouse stopped working and now I'm bootng the old kernel (3.5.0-17) with everything working fine.
What can you-all tell me?
