The Mainlog.txt shows that you can not connect to the archive server. Is your network connection configured properly, especially regarding IPv6?

"Impossible d'initialiser la connexion à fr.archive.ubuntu.com: 80 (2001:860:f70a::2). - connect (101: Le réseau n'est pas accessible)"

[Juhani Numminen (jsonic)]

If you're unsure, disabling IPv6 might help.
