I just upgraded my ubuntu server via command line to version 12.04. I was on 11.10, so when I upgraded I have to switch the sources in source.list to the old-releases.ubuntu.com source. Everything worked fine.
Anyway, now I want to upgrade again, but the problem is my server is having a problem contacted the us.archive.ubuntu.com server. When I do apt-get update I get many errors that look like this:
W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-security/universe/i18n/Translation-en Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)
Pinging us.archive.ubuntu.com doesn't work with unknown host error. I also tried ping google.com and it didn't work either. Pinging 8.8.8.8 however did work. So I am wondering what has happened. I was poking around the web and it seems like its a DNS issue, but I don't know what to do. My /etc/resolv.conf file is blank.
Does anyone know how I can fix this issue?
