MikeHalloran,
The best way to do updates on a Linux desktop is to acquire the latest media CD or DVD and do a new install. I did an update on a Red Hat desktop a long time ago, and while it worked, I was not happy with the results. Yum updates are a good idea on an internet server, but I see little point on a desktop, particularly one that is working properly.
I have a Three Hour rule. In three hours, I can reformat the hard drive, re-install Linux and have everything working perfectly. I refuse to spend three hours trying to fix something. This is possible because...
[ol]
[li]I have the media DVD.[/li]
[li]I took notes last time I installed it.[/li]
[li]My user files are on a separate partition.[/li]
[li]I don't do updates. Updates are complicated to keep track of, and I doubt they can be repeated within my three hour limit.[/li]
[/ol]
I have not had a disaster lately. I used to have a machine I eventually realized had a flakey power supply. Never was so much grief and frustration cured by the expenditure of ten bucks. I have been hacked once. When the installer asks if you want the firewall, say "Yes".
