here is my list

You need to Uncomment the rest of your repo's, save and do a sudo apt-get update. (uncomment means to delete the # sign next to the repositories) If that pound sign is there, you cannot access those repositories.

This should do the trick!

Were you paying attention? I just wrote in my very last reply that "YOU NEED TO UNCOMMENT/enable THE REST OF YOUR REPOSITORIES"!

randell6564: i hav doe it right now bot i still get problems.... i think i most try to download a new ISO and try to Reinstall my system to look about it

Well, what problems are you now having my Friend? Please be more specific.

If you have a working system and are just having problems updating, this should not be an Iso issue.

Install your OS and copy my /etc/apt/sources.list then update me on the outcome K?
