I had a Ubuntu on an older end-of-life (EOL) release that I hadn’t had a chance to upgrade. I finally took the time tonight to upgrade it, but starting out I start getting 404 errors because of the EOL status. Here are my notes for upgrading an EOL Ubuntu from 12.10 to 14.04.1.

  1. Update all references in /etc/apt/sources.lst and replace http://archive.ubuntu.com or http://us.archive.ubuntu.com with http://old-releases.ubuntu.com
  2. apt-get update
  3. apt-get upgrade
  4. do-release-upgrade
  5. Rinse and repeat for 13.10 to 14.04.1
