Bug Description

Binary package hint: update-manager

Everything went smoothly until the cleanup stage. During the clean up stage, it gave an error and a 'Report Bug' option. When I clicked it the system froze. I had to terminate the application. Then I launched Adept again and ran Full-Upgrade, Fetch Updates Full Upgrade again. At reboot, I get "Kernel Panic : cannot mount fs" or something.

I had the same problem. The update tool showed a dpkg error in subprocess while removing old packages such as old kernel etc. Then it crashed. In fact old kernel 2.6.17-11 was removed, but GRUB was not amended accordingly.

Booting with 2.6.17-10 was possible, perhaps the update tool was crashed before removing 2.6.17-10. But, restricted-modules for 2.6.17-10 were not installed. I was a bit in trouble to fix this, because WLAN was not working and manuals for editing GRUB are usually found in the web.

Since I´m lazy I installed the restricted-modules for 2.6.17-10 from the Install-CD of 6.10 and thereafter with working WLAN I reinstalled the new kernel 2.6.20 whereas GRUB was updated correctly.

Ok, here is the apt-log file. I´m not really confirm with those things, but as far as I understood the apt.log, there was a problem with nvidia-glx. Therefore it might be helpfull for you to know, that I had the nvidia drivers installed from alberto milones repository.

This problem is fixed in my local tree and the fix will be part of the next upload. It will ensure that there is a linux-image-$flavour installed that matches the installed (uname -r) flavour.

Cheers,
