Welcome to Ubuntu 18.04 LTS (GNU/Linux 4.15.0-15-generic x86_64)

 * Meltdown, Spectre and Ubuntu: What are the attack vectors,
   how the fixes work, and everything else you need to know
   - https://ubu.one/u2Know

 * Canonical Livepatch is enabled.
   - All available patches applied.

0 packages can be updated.
0 updates are security updates.


You have packages from the Hardware Enablement Stack (HWE) installed that
are going out of support on 2016-08-04.

To upgrade to a supported (or longer-supported) configuration:

* Upgrade from Ubuntu 14.04 LTS to Ubuntu 16.04 LTS by running:
sudo do-release-upgrade 

OR

* Switch to the current security-supported stack by running:
sudo apt-get install linux-generic-lts-xenial

Besides, it always says, I should reboot, I have rebooted many times.

    This might be the case because 18.04 hasn't been released yet and therefore is out of support ... Sit this out until tomorrow and see what happens (and maybe file a bug report for this message). – Sven Apr 25 '18 at 16:58
  • well, it is the same story. i am bionic, but it says i should from 14.04 to 18.04, hmmm – Patrik Laszlo May 01 '18 at 14:00
  • While this is on topic here, you are more likely to get a good answer at our sister site [ubuntu.se]. This might also be a bug requiring a bug report to be filed at Launchpad. – Michael Hampton May 08 '18 at 15:02

This happens because you most likely have leftover packages from previous Ubuntu versions.

You can run hwe-support-status --show-all-unsupported as root to figure out which packages are causing it, then run apt --purge remove on each package to get rid of them.

Afterwards the error goes away.

  • i am already on bionic. as it says, but it says: hwe-support-status --show-all-unsupported => linux-headers-generic-lts-utopic linux-generic-lts-utopic, so i should remove and purge this and then you got the bounty if it works??? :) – Patrik Laszlo May 15 '18 at 09:57

    Yes, once you purge those packages, the error should go away. – Ari 'APz' Sovijärvi May 15 '18 at 18:49

My install was from an Ubuntu 14 Server iso, upgraded via CLI over time to 16 then 18. If yours is a similar pattern, then check out the instructions on LTSEnablementStack which made the message go away for me.

Depending on which release you're on (here's the instructions for 18.xx):

sudo apt-get install --install-recommends linux-generic-hwe-18.xx

After upgrading, I now see this after logging in.

Your Hardware Enablement Stack (HWE) is supported until April 2023.
