apt - Ubuntu roll back to previous kernel: linux-image-3.11.0-11

I had too many kernel updates and the only ones that worked for me were "pushed away".

Any suggestions on how can I reinstall kernel version "linux-image-3.11.0-11"?

You can install any kernel version that is in the repositories.

For example, for the 3.11.0-11 (for Ubuntu 13.10) kernel, invoke as a terminal command:

sudo apt-get install linux-image-3.11.0-11-generic
