I've 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

Well, I solved my trouble. Here you can check latest version of kernel for Ubutnu

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

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.

There are two ways to do this


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?
