Hello! This is the first time I have had a problem with Ubuntu and I am stuck! I would love some help please. I am trying to do an upgrade to Ubuntu LTS 12.04 and everytime I try to upgrade to it I get the following error message:
W:Failed to fetch http://us.archive.ubuntu.com/ubuntu/...se/Release.gpg Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)
, W:Failed to fetch http://security.ubuntu.com/ubuntu/di...ty/Release.gpg Something wicked happened resolving 'security.ubuntu.com:http' (-5 - No address associated with hostname)
, E:Some index files failed to download. They have been ignored, or old ones used instead.
Thanks in advance for any help!
