I just ran a normal update through the update manager that wanted to update me to linux-image-3.2.0-26-generic. The installation paused halfway with a message that the root was full. I checked the disk usage, and noticed that one of the newly installed files: /lib/modules/3.2.0-26-generic/modules.ccwmap took up 63GB(!). Compared to the previous version: /lib/modules/3.2.0-24-generic/modules.ccwmap that took up only 4KB it seems like something went awfully wrong!

As mentioned the update was paused when i ran out of disk space. There is no option in the update dialog to cancel or perform rollback on the update. Is it asking for trouble to kill the update manager?

Any ideas as to what went wrong, and what I can do to remedy it? It's only minimal how much space I can free on that partition (without deleting the above mentioned file).

If it is any help, the update was paused after this: Examining /etc/kernel/postinst.d. run-parts: executing /etc/kernel/postinst.d/dkms 3.2.0-26-generic /boot/vmlinuz-3.2.0-26-generic
