How to reinstall newest Linux Kernel?

Question

Hello I upgraded all packages on my Ubuntu, and kernel also. But in upgrading process kernel upgrade failed, and I must always after grub load select older kernel. It is a terminal command to reinstall latest kernel?

Run the following command in a terminal (Ctrl+Alt+T):

dpkg -l | grep linux-image-.*-generic

Look for the kernel version you want to reinstall then run:

sudo apt-get install --reinstall linux-image-3.X.Y-ZZ-generic

_{Of course, you must type the actual kernel version (e.g. linux-image-3.8.0-21-generic) instead of linux-image-3.X.Y-ZZ-generic.}

Or as one-liner dpkg -l | grep linux-image-.*-generic | sort -k3 | tail -n1 | awk '{system ("sudo apt-get install --reinstall " $2)}' – A.B. Sep 04 '15 at 12:03
Thank god! This just fixed a networking problem I could not figure out! – BuvinJ Aug 31 '17 at 18:19
Since there is also a package called linux-image-generic 9with no version number), should I do something with that, too? – J. B. Rainsberger Sep 01 '21 at 09:20
