Comment 18 for bug 341402

to fix update-manager you need to:
sudo apt-get install --reinstall update-manager update-manager-core

then do sudo touch /forcefsck
and to be sure sudo shutdown -F -r 0
then install lang packets and every thing else.

But your system will be still colapsing unluckly...
I had to reinstall rhytmbox compiz metacity sed, whole filesystem support,

My laptop is T9400, 4gb,wd320@7200,96gt-m,i4965agn and i can get stable 9.04 only on virtualbox :/
I am 100% sure that my laptop is not the issue smart is good no error , cpu/ram/gpu/vram is also stable. On 8.10 i have only problems with 180.11 drivers. W7 works great eh...
