Thanks to all the hard work from our contributors, Lubuntu 22.04.2 LTS has been released. With the codename Jammy Jellyfish, Lubuntu 22.04 is the 22nd release of Lubuntu, the eighth release of Lubuntu with LXQt as the default desktop environment.

Support lifespan

Lubuntu 22.04 LTS will be supported for 3 years until April 2025. Our main focus will be on this and future releases.

Lubuntu 20.04 LTS will be supported until April 2023, and we are limiting changes to critical fixes and underlying system changes shipped with all other Ubuntu flavors. Lubuntu 22.10 is likewise limited to critical fixes and underlying system changes being supported until July 2023.

What’s The Difference Between Lubuntu 22.04 LTS And This Release?

Lubuntu 22.04.2 is a set of images produced for convenience so that a fresh install of the latest Lubuntu LTS does not require as many updates after install (as Lubuntu continues to release Stable Release Updates and security fixes to make your experience as smooth as possible and to fix any bugs, if you want to help us out with this, see below, we always need more help). If you do system updates regularly, you are already running Lubuntu 22.04.2 LTS, and if you install Lubuntu on a system using a Lubuntu 22.04 LTS image and do system updates, that system will also then be running Lubuntu 22.04.2 LTS.

This Lubuntu 22.04.2 media also contains the updated HWE 5.19 kernel stack (from Lubuntu 22.10) where prior 22.04 media contained only the 5.15 GA kernel stack.

What is Lubuntu?

Lubuntu is an official Ubuntu flavor which uses the Lightweight Qt Desktop Environment (LXQt). The project’s goal is to provide a lightweight yet functional Linux distribution based on a rock-solid Ubuntu base. Lubuntu provides a simple but modern and powerful graphical user interface, and comes with a wide variety of applications so you can browse, email, chat, play, and be productive.

You can find the following major applications and toolkits installed by default in this release:

• LXQt 0.17.0 – more information here.
• Qt 5.15.3
• Mozilla Firefox will be shipped as a Snap package with version 110 and will receive updates throughout the support cycle of the release.
• The LibreOffice 7.3.2 suite.
• VLC 3.0.16, for viewing media and listening to music.
• Featherpad 1.0.1, for notes and code editing.
• Discover Software Center 5.24.6, for an easy, graphical way to install and update software.

You can find a variety of other applications installed which aim to enhance your experience while staying out of the way of your normal workflow.

Please note: The change of firefox to snap package, results in the browser being slower to start. It does not impact execution or subsequent runs during that session. The reason for this is the setting up of the confined environment in which snaps run, and decompress the squashfs, with privacy and security benefits. This is noticeable on first run especially with live media having improved significantly when compared to prior Lubuntu 22.04 LTS media.

If you’d like to use LXQt 1.2 on your existing, or new Lubuntu 22.04.2 LTS install, then please see how to upgrade it with the use of the Lubuntu Backports PPA link here.

Upgrading Lubuntu to 22.04 LTS

Notice about upgrading from Lubuntu 20.04 LTS with LXQt:

If you are upgrading from Lubuntu 20.04 LTS that has LXQt, this new version uses a different Openbox settings configuration file. If you have customized ~/.config/openbox/lxqt-rc.xml you will want to copy that file to ~/.config/openbox/rc.xml. New installations are not impacted by this change.

New installs of Lubuntu 22.04 LTS no longer include the programs trojita, fcitx and k3b, which will cause those applications to be removed from your existing system on upgrade, unless you mark them as manually installed using the procedure we’ve documented here. You should do this for each of the programs you use, before you perform the upgrade.

For more information about upgrading please visit our manual page that describes the process. In addition, more information about upgrading releases in Ubuntu and all the flavors for the 22.04 release, can be found here

Where can I download it?

You can download Lubuntu 22.04.2 LTS on our downloads page.

Installer

Lubuntu uses the Calamares system installer in place of the Ubiquity installer that most other flavors use. 22.04 ships with Calamares 3.2.60. For a full/erase disk install, we have added the option of a swapfile by default. The swapfile size is initially set to 512 MB. The option for no swap is still available as a dropdown selection.

For a full description of the new features and fixes, see the upstream announcements for 3.2.60. You’ll note this is a later calamares than initial Lubuntu 22.04 LTS media provided.

Lubuntu Manual

The Lubuntu Team has been hard at work in polishing the Lubuntu Manual to make it easy for new and experienced users alike to use their system more productively. The book can be found at manual.lubuntu.me.

We want to thank Lyn Perrine for all the hard work she has put into the Lubuntu Manual. Thank you!

All existing URLs now redirect to https://manual.lubuntu.me/stable/. Going forward, the tip of the master branch (WIP documentation for the next release) can be found at https://manual.lubuntu.me/master/, and documentation for Lubuntu 22.04 LTS can be found at https://manual.lubuntu.me/lts/. While the documentation for previous releases will be kept in the Git repository, they will not be published anywhere.

Lubuntu Project

How can I help?

We can always use more help! No matter your skill level or your technical experience, there’s something you can help with that can make a huge difference in Lubuntu. Join us on our chat (which is bridged three ways to Matrix, Telegram, and IRC) and talk to us there. Whether you know another language, have some spare time to help us test Lubuntu, are good at writing documentation, or just want to stay “in the know,” that is the place to be. More information about contributing can be found here.

If you want to contribute to Lubuntu but do not feel you have the time or skills, consider buying a t-shirt or donatingto Lubuntu.

Another great method to get involved is bug reporting. If you notice an issue, please file a bug using the instructions on the Lubuntu Wiki.

Don’t want to file a bug? Let us know what the problem is (in detail, enough that we can reproduce it) and we can assist you in filing one or do it ourselves.

Global Team

The Lubuntu Global Team has been created to foster communities in non-English languages and locales, and includes Hans Möller, Noumeno, and Jyoti Gomes as the initial drivers of the project. An up-to-date list can be found on our Links page, but the existing groups include: Spanish, Portuguese, Russian, Italian, Chinese, German, Japanese, Arabic, and French. If you would like to start a language group, join our development channel and talk with the Global Team. At minimum, you should have a few interested drivers of the community, and at least one administrator that speaks English.

We now have multiple languages available in the support section of our Discourse forum.

Resolved Bugs

The original Lubuntu 22.04 LTS media when used to install with a btrfs file-system usually resulted in an unbootable system due to this bug. This did not affect upgraded systems, impacting only new installs using BTRFS file-systems and 22.04 media; this issue will not impact new installs of Lubuntu 22.04.2 LTS.

The lubuntu-update-notifier did not prompt users when configuration files conflicted with installed versions. In addition, if lubuntu-update-notifier was interrupted during an upgrade there was no mechanism to handle that. Further information can be found on our Discourse post.

Known Bugs

Libreoffice online help is currently not usable due to a confinement issue with the firefox snap and snapd and this issue. This is not a Lubuntu specific bug, and expect this issue to be fixed soon.
