Could you post your new sources.list file that worked. coming from a new install i basically can't get anything.
Unfortunately the sources.list that I used to install has been written over. To get the installer to work I modified my sources.list and changed all references from "us.archive.ubuntu.com" into "old-releases.ubuntu.com". I then commented out all of the lines containing "universe", "multiverse" or "security".
/var/log/pluto/ConfirmDependencies.log may be able to help you.
I got the gc100 to install correctly including socat by re-adding a reference to old-releases.ubuntu.com universe. ConfirmDependencies.log only said "01 Error processing package socat" -- is there a way to turn up the logging verbosity globally to help debug?
Also -- My sources.list that I used to install appears to have been written over. Along with this, another reference has been added to archive.ubuntu.com which results in a 404. I believe the ConfirmDependencies program does this (http://wiki.linuxmce.org/index.php/Confirmdependencies
) but I have not had time to dive into the code to verify where the old references are coming from.
