I am using Lubuntu 19.04 and am very pleased with the speed and performance however support has now ceased for this iteration. The question is should I go back to Lubuntu 18, as suggested, or switch to Ubuntu. My PC is a virtually new HP Pavilion with plenty of grunt.

From the Lubuntu EOL message is

Lubuntu 19.04 End of Life and Current Support Statuses

Lubuntu 19.04 (Disco Dingo) will reach End of Life on Thursday, January 23, 2020. This means that after that date there will be no further security updates or bugfixes released. We highly recommend that you update to 19.10 as soon as possible if you are still running 19.04. After January 23rd, the only supported releases of Lubuntu will be 18.04, with LXDE, and 19.10, with LXQt. All other releases of Lubuntu will be considered unsupported, and will no longer receive any further updates from the Lubuntu team.

You can find instructions on how to upgrade your Lubuntu installation here at our manual page.

You'll also note later in the reference, the reason I'd suggest not returning to Lubuntu 18.04 LTS, ie.

Note, due to the extensive changes required for the shift in desktop environments, the Lubuntu team does not support upgrading from 18.04 or below to any greater release. Doing so will result in a broken system. If you are on 18.04 or below and would like to upgrade, please do a fresh install. The installation image can be obtained from our downloads page.

I would strongly recommend the upgrade to 19.10, providing a path to move to Lubuntu 20.04 LTS currently in development.

    fyi: @K7AAY I'm not adding this answer because there is anything wrong with your answer, I wanted to include the Lubuntu specific references/details – guiverc Feb 4 at 1:45

    If you go back to Lubuntu 18.04 LTS (we're QA-testing the 18.04.4 ISO's currently; the i386 on the machine to my left is mid-install), you'll have support until April-2021 (3 years from April-2018), where as the 19.10 will upgrade to 20.04 which has 3 years just for starters.. ie. a much longer support path without the hassle of re-installs... – guiverc Feb 4 at 2:00
  • As an unlikely aside; if your system was x86 (32-bit) which officially was never released, though ISOs were produced for x86 Lubuntu & Xubuntu for the first third of the release cycle, thus upgrades were generated & available. There is however no 19.04 to 19.10 upgrade possible. That was disabled a few days before 19.10's release. In this circumstance I'd recommend re-installing a 18.04 system as its supported. – guiverc Feb 10 at 0:13

Neither. You do not need to reinstall Lubuntu 18.04 or start over with Ubuntu 18.04 LTS, because you can upgrade to Lubuntu 19.10, which is very easy, and fully supported.

This is a general solution for all users of Ubuntu, Lubuntu, Kubuntu, and other supported Ubuntu flavours.

sudo apt update && sudo apt dist-upgrade  
sudo apt install update-manager-core  

=

For reference only, if performing an upgrade from an LTS version (not the case here), also do

sudo nano /etc/update-manager/release-upgrades   

On the file's last line, change the value of Prompt from lts to normal .

Save the edit with Ctrl-O, then press Enter to confirm and exit with Ctrl-X.

=

Either way, continue with do-release-upgrade .

When it completes, reboot, and run lsb_release -a to confirm 19.10 is installed OK.

    Why are the last 2 steps required? Wouldn't it be normal by default if the OP is already on 19.04 (19.04 was not an LTS release)? – Dan Feb 4 at 9:48
  • You mean "at the last line of the file, change the value of Prompt from lts to normal ." and not the last two steps "When it completes, reboot, and run lsb_release -a to confirm 19.10 is installed OK." ? You are technically correct, but sooner or later someone here will use this for an LTS, so I am just belt-and-suspendering this. – K7AAY Feb 4 at 17:11
  • Yes sorry, I meant to say the last 2 commands regarding the installation of update-manager-core and editing the /etc/update-manager/release-upgrades file. – Dan Feb 5 at 8:19
