I'd like to know the exact steps that need to be taken to get Ubuntu 16.04 LTS support past April 2021 through to the year 2024.

I've read about Extended Security Maintenance (ESM) and this sounds like a viable option.

Can anyone spell out the exact steps that need to be taken and what costs if any are incurred?

    @pLumo "What I exactly don't understand" is the condescending tone in your comment. All you had to do was post an answer with that link and point out it is free for three machines. Or if an existing question and answer exists you could have voted to close my question. Dec 20, 2020 at 22:24
  • I think you misunderstood my comment. It was not meant to be rude at all. I meant that you might want to clarify / focus your question a bit on what details you want to know. > "Sharing your research helps everyone."

    @pLumo I don't mean to get involved, but I have to admit that "What exactly don't you understand?" is fairly condescending in English, at least. Certainly a "Does this link help?" or "Is this what you're looking for?" would have been much better...

Extended Security Maintenance for Ubuntu 16.04

First priority when retaining Ubuntu 16.04 is security. This means signing up for Ubuntu Advantage (UA) client and installing ESM.

The Ubuntu discourse page for information on installing Ubuntu ESM is https://discourse.ubuntu.com/t/ubuntu-advantage-client/21788. the page directed me to https://ubuntu.com/advantage where I completed the registration process and ended up with a free token.

Back on https://discourse.ubuntu.com/t/ubuntu-advantage-client/21788 I continued with Installing the UA client by running a couple of commands as instructed. Next I proceeded to Attach the UA client. I ran the line I got when registering sudo ua attach [TOKEN_ID], (Please use your own free token).

Running sudo ua status I confirmed that ESM was enabled.

I completed the upgrade by running sudo apt update and then sudo apt upgrade. The installer ran for quite a while.

I ran Software Updater and It installed quite a few security updates. All Settings/Overview tells me System Up-To-Date.

  • I have tried this and it's not clear that it works. When singing up for Ubuntu Advantage, it says on the page where the token is obtained, that the token is only valid for 14.04. Upon trying to use it with 16.04, ua status shows that esm-infra and livepatch are both enabled, but ubuntu-support-status still shows that 100% of packages are not supported. May 5, 2021 at 14:41
  • @Stefan Dawydiak It is getting late here, I will try to have a look in the morning. May 5, 2021 at 14:46
  • Thank you, I hope they do indeed have community support for 16.04 servers May 5, 2021 at 14:51
  • @Stefan Dawydiak: Have a look here: ubuntu.com/16-04. I am not sure what the stuff from ubuntu-support-status means. May 6, 2021 at 5:09
  • Thank you, I have found that page already and used my token. Running ua status tells me it's working correctly, too, but I unattended upgrades hasn't seen fit to upgrade anything since May 4, before I used my token. However, it seems that ubuntu-support-status works in a rather naive way, even after the bugfix here: bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1574670 May 6, 2021 at 16:33
