My updates will not install on Ubuntu 12.04. It gets to 93% and then gets an error of an (address not found) No host name associated with http(ubuntu.com/etc. etc.
I have used the command:
sudo apt-get clean and
sudo apt-get update; && sudo apt-get upgrade. But it stalls on 93%. I really need to fix this problem as it will not let me take updates.
My update manager says no authentic or something like that. Please help. Thank you.
