# Same problem here with upbgrade of 2.6.35-29-generic. Tried to mount and install from the alternate disk iso using:
sudo mount -t iso9660 -o loop /home/username/ubuntu-11.04-alternate-i386.iso /cdrom
then
sudo /cdrom/cdromupgrade
And got the same "abort" message you got.

[-Rif-]

this problem has been solved?
whats the solution? I'm having the same problem
