I tried at least 5 mirrors from ubuntu and none of them seems to have them. I finally found the solution in this post which is to add the following in /etc/apt/sources.list

deb http://old-releases.ubuntu.com/ubuntu/ edgy main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy main restricted
deb http://old-releases.ubuntu.com/ubuntu/ edgy-updates main restricted
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu/ edgy universe
deb-src http://old-releases.ubuntu.com/ubuntu/ edgy universe
deb http://old-releases.ubuntu.com/ubuntu/ edgy-backports main restricted universe multiverse
