August 5, 2014 3.1k views


I recently got the security warning below on my ubuntu precise LTS

Your current Hardware Enablement Stack (HWE) is going out of support
on 2014-08-07. After this date security updates for critical parts (kernel
and graphics stack) of your system will no longer be available.

I ran both options but the warning is still there:

dicix@dicix:~$ sudo apt-get install linux-generic-lts-trusty linux-image-generic-lts-trusty
[sudo] password for dicix:

dicix@dicix:~$ sudo do-release-upgrade

Distributor ID: Ubuntu
Description:    Ubuntu 12.04.4 LTS

Any ideas?

Ubuntu will display that message if the file /var/lib/update-notifier/hwe-eol exists. I've seen a few reports that it isn't being properly updated after people upgrade their kernel version. You can safely remove that file. It will be recreated on a reboot if you indeed still have the have the old kernel in use.

If that's the case, make sure you've set the kernel in the DigitalOcean control panel to match the one that is installed on the droplet. The virtualization that we use requires that a matching kernel be found installed in your libraries in the OS and is also found on the hypervisor settings for your droplet, which is set through the control panel.

  • uname -r tells you the version the control panel is using
  • ls -lah /lib/modules shows you the libraries you have installed

To change it in the control panel, you need to poweroff the machine. Then go to the control panel, click on the droplet, click "settings" and then "Kernel". Next click the list and find the right version that matches your kernel libraries .e.g * Ubuntu 14.04 x64 3.13.0-30 Finally boot the droplet using the control panel.

Thanks for the suggestions! Choosing the right version in the control panel did the trick.
