How to verify latest kernel version?

Question

I installed Xubuntu after Ubuntu, running in dualboot. So Xubuntu controls the grub. Every time I update kernel on Ubuntu - will Ubuntu load the latest version of a kernel? (I mean the grub is not updated, it may be updated by Xubuntu. And I don't want to write the grub to MBR from Ubuntu)

I can't find information which is latest kernel version for trusty, but mine is 3.13.0-24-generic

Depends on your Xubuntu grub menu. Most times it is fixed to a kernel version it reads from Ubuntu's grub menu and you need to run sudo update-grub in Xubuntu to find the new entry in Ubuntu. — oldfred, Jun 19 '14 at 19:59

To check what kernel version you are running; $ uname -r

As your grub controlled by Xubuntu, you should update the grub by typing;

sudo update-grub

make sure to run this command on Xubuntu as it is the one who control the grub

Also note, when you do $ sudo update-grub it will automatically detect present kernel versions on both partitions and update the grub accordingly.

Well, I solved my trouble.
Here you can check latest version of kernel for Ubuntu
https://launchpad.net/ubuntu/+source/linux

I checked it, and installed the package linux-generic-lts-trusty. Then rebooted, then entered uname -r in terminal - the version was the same. The problem wasn't solved. So I installed grub-customizer and wrote GRUB to MBR. After another reboot I have the latest kernel.

You said in your question that you don't want to control the grub from Ubuntu. So, this is not answering the question – Anwar Nov 12 '16 at 14:27

There are two ways to do this

1.

first of all know your current version by typing following command in terminal

uname -r

then check on this link to know that your running system is the latest one available in market

2. You can also if you are not running a LTS version you will be prompted that a new version is available.

If both methods do not satisfy you read this How do I upgrade to a newer version of Ubuntu?
