I'm trying to upgrade from 13.04 to 13.10 following this guide: http://www.unixmen.com/upgrade-ubuntu-13-04-raring-ubuntu-13-10-saucy-salamander/

user@computer:~ update-manager
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.

  1. I had apt-cacher installed.

    https://help.ubuntu.com/community/Apt-Cacher-Server

    Remove or edit the proxy file you added in /etc/apt/apt.conf.d/ to bypass apt-cacher.

  2. I was getting "Failed to fetch" too. Changing the software sources in "Software & Updates" back to the "Main server" servers instead of the country specific "Server for country" let the upgrade continue.
