Ubuntu – Kernel downgrade after update broke the system


I need to downgrade from 3.8.0-33 to version -29. After booting the latest kernel I'm greeted by a black screen. How do I keep this version permanently?

Output of dpkg -l linux-image*

Sorry it's German.

Best Answer

You can remove the non-functional kernel with apt-get:

sudo apt-get purge linux-image-3.8.0-33-generic

As part of uninstallation process the system removes 3.8.0-33 entry from GRUB menu and leaves only 3.8.0-29.

Please note, that also package linux-image-generic-lts-raring will be removed. That means that your kernel version will not be upgraded in future with apt-get upgrade. Only when you reinstall linux-image-generic-lts-raring will the kernel version get upgraded. So this is a permanent solution.
