Ubuntu updating connection failed


It tries to connect, but says "Waiting for headers".If i try to install other packages it says "Connection failed".If you don't believe you should be using a proxy server: Go to the Chrome menu - Settings - - Show advanced settings - Change proxy settings...- LAN Settings and deselect "Use a proxy server for your LAN".Thanks Hi everyone I am using Ubuntu 11.10 64 bit Intel build machine.earlier it was updating regularly and now its says " failed to download repository information.. my internet connection is working fine as i am browsing and surfing everything on the same computer.
