There's an issue with an Alpha/Beta Release of Ubuntu, what should I do?
How do I fix a “Failed to download package files” error?
I recently installed Ubuntu 12.10 daily build. At first everything was OK, but after a few updates, now the software updater always says no internet connection detected. I can update and upgrade through terminal by entering sudo apt-get update and sudo apt-get upgrade but software updater doesn't work. It will say "checking for updates" for sometime and then will say
no internet connection detected.
I downloaded synaptic package manager and even in that software when I click on reload, it says the same thing.
Of course I am still connected to internet when I am trying all this as I can still browse the net. My connection speed is fast as well so that should not be a problem.
