Thanks for your help. It's clear that the "Manage Repositories" tool shows the /etc/apt/sources.list file.
Last time (i.e. from Edgy to Feisty) I solved the same problem by adding the Feisty repositories by hand in that file. I put my sources.list file as an attachment I don't understand what "Enable the "Recommended updates" and "Pre- released updates" repository" mean. I looked on internet at the repositories list and I can find * feisty-backports/ * feisty-proposed/ * feisty-security/ * feisty-updates/ * feisty/ No "Pre-released updates", and of course I tried to drill down in the directories.
