Comment 1 for bug 571470

correction, I meant intrepid ->jaunty.
have also learned what not to do:
if you have tried the above and notice the "updates available" icon. DO NOT click on install updates. Doing this runs updates off CD which are incompatible with intrepid. End result when re-boot is a drop into initramfs shell due to "Gave up waiting for root device."
Any clues on how to get past this? right now I can't login as root on my machine and therefore cannot backup my home directory before re-installing.
