Hi,

I am using Ubuntu 18.04. Just doing the usual apt-get update/upgrade has updated my installation to 18.04.1.

I read here in the forum (https://ubuntuforums.org/showthread.php?t=2397526&p=13788342#post13788342) that if I don't upgrade the kernel manually using it wont upgrade the kernel on its own.

I am atm using


$ uname -a
Linux ubuntu 4.15.0-30-generic #32-Ubuntu SMP Thu Jul 26 17:42:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Is there anything called a Long Term Support kernel ?

Am I using a LTS kernel ?

However, if one wants to remain on the original GA (General Availability) stacks, the options are:

Install from a previous 12.04.0/12.04.1/14.04.0/14.04.1/16.04.0/16.04.1 point release and update. Previous releases are archived at http://old-releases.ubuntu.com/

Perform an update or upgrade to an LTS release from a previous release.
Perform a network install using the netboot images rather than the new <release>-netboot images.




So if I want to stay with the "GA (General Availability) stacks" simply running apt-get update / upgrade from 18.04.1 will do ?

In short yes. :)
EDIT: More information.
Don't forget you can check with: "hwe-support-status --verbose"
Hardware Enablement Stacks (HWE) are incorporated into installers for select Ubuntu LTS (Long Term Support) point releases. It is a special Ubuntu feature that provides an LTS release with hardware support introduced in newer Ubuntu releases. For Ubuntu 12.04 the point releases are .2/.3/.4/.5 and the corresponding Ubuntu releases.

This is what I get


$ hwe-support-status --verbose
You are not running a system with a Hardware Enablement Stack. Your system is supported until April 2023.

That is expected. The .1 is the first point release of 18.04. They typically have 5 point releases over the lifespan of a particular LTS version.


Am I using a LTS kernel ?
Type the following at a terminal:

lsb_release -a

You should get something like:

:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic

You can see from the description that it identifies itself as Ubuntu 18.04.1 LTS.

Just means you are running the "GA (General Availability) stacks"

Yes but for example in Linux Mint which is based on LTS releases we can install a variety of kernels which may not be a LTS kernel. Thats why I ask if the kernel I am using is a LTS kernel or not.
