Ubuntu – 12.04 upgrade from 11.10 stuck at restoring previously installed packages

11.1012.04installationpackage-managementupgrade

I am trying to upgrade from 11.10 to 12.04.
The machine is acer aspire core i3, 2.1ghz, ram 6gb, hard disk 500 gigabyte.
I am using a usb stick with a downloaded 12.04 live install.
The install progressed with an overwrite of 11.10 system files to 12.04 and then got stuck.
The install is stuck at 'restoring previously installed packages'
How can i recover from this situation ?
please help.

Firstly, if you are upgrading, you should have used the update manager instead of a livecd to upgrade. If your system is being overwritten, then your home folder may get overwritten unless it is in a separate drive.

How long has it been since it got stuck? Sometimes, during upgrade, things can appear to get stuck but in the background the upgrade may be running.

Check using top command in an open terminal which process is using the most cpu/ram. Generally the process which gets stuck eats the most CPU.
