Comment 68 for bug 574886

I have two different slices on slicehost.com (great host!), two different domains. Ubuntu 10.04 on each. I installed Ruby enterprise edition, mysql, and lots of good stuff on both using aptitude or apt-get. All was fine in paradise.

Then, I had to use a remote email system (at work) for one of the slices. This involved switching the dns to use the nameserver zones set up at work and they pointed back to the www .com pages on the slices. This was a work around, but it worked. Among other things to make the switch, I changed the resolv.conf to point to the new nameservers.

Several weeks latter, i first noticed, and for weeks, the apt-get failed only on the slice I had changed giving lots of errors when trying to use aptitude update/install or apt-get update/install, but the other slice was fine. Errors as described above:
Something wicked happened resolving 'archive.ubuntu.com:http' (-5 - No address associated with hostname) errors.

I resolved this by adding the google public nameservers to the resolv.conf right after the two name servers from work and rebooting:
nameserver 8.8.8.8
nameserver 8.8.4.4

Hope this helps!
