So, I tried.
Mostly it was OK but there were a few glitches.
The installation failed for me because it attempted to remove an old version of linux that was not there. For me this was linux-restricted-modules-2.6.28-11-generic
In order to delete it you would normally
$ sudo apt-get remove linux-restricted-modules*
$ sudo apt-get autoremove
But that did not work. The remove task complained that certain files did not exist. So I simply created the following folders:
created a file in volatile
# touch /lib/modules/2.6.28-11-generic/volatile/dummy.txt
copied an existing System.map file in /boot to :
copied an existing initrd.* file from /boot to:
Then I ran the apt-get commands again and it stopped complaining
Then I removed the files I created and some others that were put there during the apt-get
# rm /boot/System.map-2.6.28-11-generic
# rm /boot/initrd.img-2.6.28-11-generic
# rm /lib/modules/2.6.28-11-generic/volatile/dummy.txt
# rmdir /lib/modules/2.6.28-11-generic/volatile
# rm /lib/modules/2.6.28-11-generic/*
# rmdir /lib/modules/2.6.28-11-generic
Seemed to work for me since when I next ran Update Manager and this time it finished working without an error.
