Public bug reported: I had DNS resolution problems after upgrading to 12.10 from 12.04. It is a desktop install, but I may have done something wrong by letting it install unattended overnight.
I was able to fix this within an hour or so by configuring the network manager and /etc/dhcp/dhclient.conf to point to 8.8.8.8, which is Google's DNS system. From there, all sites within a browser worked fine. However, I was unable to perform any updates or use the Software Center. A sudo apt-get update would fail to download or find the Ubuntu mirrors (if that's the right term). I played around so long with different config options (see below), that I realized my system was totally fixed and no longer needed Google's DNS IP, so I edited it out and replaced it with the default 192.168.1.1. Running nm-tool showed me the correct DNS of 192.168.1.1: the same for the "Show Connection Information" option in the network manager. However, apt-get update still pointed to Google's 8.8.8.8. After many hours of Googling, I found this post (http://serverfault.com/questions/81234/ubuntu-server-update-issue) that discussed the possibility of a proxy config problem. I edited /etc/apt/apt.conf to include a proxy pointing to us.archive.ubuntu.com, and this almost seemed to fix it - Google's 8.8.8.8 was gone, replaced by us.archive.ubuntu.com. However, updates still failed to come in. sudo apt-get update would show a long list of files, some HITS, some IGNs, and a few W's at the end - see below. First of all, the 8.8.8.8 address must be cached somewhere in order to keep popping up like this. Secondly, the apt-get update output tells me at the very end there could be something wrong with sources.list. I have checked /etc/apt/sources.list and I don't see how it could be a source of problems, but who knows. Finally: after adding /ubuntu to my proxy I mentioned, while the update manager still displays a "Failed to download repository information" message, it was able to tell me that I had 11 MB of updates from a previous check and download and install them completely through the GUI. I don't know if that helps or not. Lastly: is all I need to do at this point is just add the partner source list? I'm curious now. Stuff I did to try and get it to work (more detail above): * editing /etc/network/interface and adding my 192.168.1.1 interface, * editing /etc/dhcp/dhclient.conf and adding a prepend value of 192.168.1.1 * running sudo apt-get autoremove (which I believe removed resolvconf for me, along with three other packages) #output of very end of apt-get update file list W: Failed to fetch http://archive.canonical.com/ubuntu/dists/quantal/Release Unable to find expected entry 'partner/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/main/binary-i386/Packages 404 Not Found [IP: 91.189.91.14 80] W: Failed to fetch http://dl.google.com/linux/talkplugin/deb/dists/stable/main/binary-i386/Packages 404 Not Found [IP: 91.189.91.14 80] E: Some index files failed to download.
