If I look in my /etc/apt/sources.list and copy a URL from there I can browse the repositories from a web-browser. They exist, they certainly contain a bunch of software, but they themselves don't appear to be getting updated anymore?
I may try Launchpad answers or the ubuntu forums. If I find out whats going on, I'll post back here.
Did all the updates, now my machine seems to hang between 'starting up...' appearing and the progress bar appearing. I've got a feeling it's got something to do with menu.lst, but I can't see any differences between mine and my daughters which runs fine after the update.
Several months ago I got the last security updates, but I have not got any further updates since April. Even firefox is not updated. I am still using version 3.0.10 instead of 3.0.14. Or is there anything wrong with my nb100? I have also reported this on launchpad.
