When I try to update the software updater says check your internet connection. (Failed to access repository information)

My Internet is working just fine.

I have tried many different servers. (Main,US,ext.)

Also, I do not have a proxy.

Open a terminal, type sudo apt-get update and tell us what the result was (preferably paste the output). –  January Jul 8 '13 at 10:47

The comments below the question already mention that this doesn't work. I'm flagging this answer for deletion. –  MadMike Feb 6 at 12:29
I faced the same error on my machine and 'sudo apt-get update' solved the problem. I think its worth the try for other people who are facing this issue. –  Deenbandhu Prasad Feb 20 at 14:05
