I just upgraded from 13.10 to 14.04, but when I do uname -r, it says I have kernel 3.11. I want to have the default 14.04 kernel, (3.13 I believe). How can I get this?

  • No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04 LTS Release: 14.04 Codename: trusty – shawn221 Apr 18 '14 at 16:41
  • May be the same as http://askubuntu.com/questions/364156/ubuntu-13-10-kernel-still-3-8-0-31-generic? In that case my answer should work: http://askubuntu.com/a/387316/16395 – Rmano Apr 18 '14 at 16:43
  • Thanks to Rmano's comment. I followed the thread and did the solution that you left on it and it worked. Thanks! – shawn221 Apr 18 '14 at 16:50

This is very similar to Ubuntu 13.10, kernel still 3.8.0-31-generic --- answering here so that this is a more generic question/answer.

Sometime in the upgrade process the kernel meta-packages are "lost". The basic solution is to reinstall the generic kernel package: 

sudo apt-get install linux-generic

which should give you the correct kernel packages and headers after a:

sudo apt-get update; sudo apt-get upgrade

(obviously if you have -rt or -lowlatency or other "flavored" kernels you have to adapt this to your case)

Sometime the system is (wrongly) convinced it has the newest kernel: in that case, try 

sudo apt-get install --reinstall linux-generic
