Lubuntu 20.04 (Focal Fossa) was released April 23, 2020 and will reach End of Life on Friday, April 28, 2021. This means that after that date there will be no further security updates or bugfixes released for your Lubuntu packages. We highly recommend that you upgrade to Lubuntu 22.04 LTS as soon as possible if you are still running Lubuntu 20.04.
After April 28th, 2023, the only supported releases of Lubuntu will be 22.04 (until April 2025), 22.10 (until July 2023), and 23.04 (until Jan. 2024). All other releases of Lubuntu will be considered unsupported, and will no longer receive any further updates (or support) from the Lubuntu team.
You can find instructions on how to install or upgrade Lubuntu in our manual.
After months of clawing our way through development, testing, and bug fixing, the Lubuntu team is thrilled to shell-ebrate another successful release cycle! We’ve finally pinched a working copy of the Lubuntu operating system, and it’s our biggest catch yet: Lubuntu 23.04 Lunar Lobster, the 24th release of Lubuntu and the tenth to feature LXQt as its default desktop environment. So let’s all shell-ebrate with some Lunar Lobster puns!
Support lifespan
With 23.04 being an interim release, it will follow the standard non-LTS support period of nine months; this means that 23.04 will be supported until January 2024. Our development focus going forward will be on 23.10 and future releases, so only critical bugfixes and security updates will be provided. If you choose to use 23.04, we STRONGLY recommend upgrading to 23.10 once it is released, before 23.04 hits end of life. If this is not suitable for you, but you still enjoy new features on a regular basis, we would recommend staying on 22.04 LTS with Lubuntu’s Backports enabled.
You can download 23.04 here. If you would like to upgrade your existing 22.10 installation, please visit our manual page describing the process. Common Ubuntu instructions can be found here.
Known Issues and Notable Changes
LXQt
A bug in LXQt results in duplicate menu entries for the Calamares installer, showing the following:
While either of these options work, we recommend using the desktop icon.
While LXQt 1.3.0 has already been released at this time, it was released after Lubuntu 23.04’s Feature Freeze. As a result, Lubuntu 23.04 ships with LXQt 1.2.0 with 1.2.1 point releases updates for a few components. We intend to ship LXQt 1.3.0 or later with Lubuntu 23.10. LXQt 1.3.0 will also be backported to Lubuntu 22.04 LTS if possible.
System Installer
In Lubuntu 22.10, we chose to ship an (at the time) very recent alpha testing version of the Calamares installer, Calamares 3.3 Alpha 2. This worked quite well, and over the past several months Calamares 3.3 has been battle-tested by our developers, our testing team, and our users of Lubuntu 22.10, with no high-impact bugs discovered in Calamares itself. We have therefore chosen to continue shipping Calamares 3.3 Alpha 2 in Lubuntu 23.04.
During testing, we did note that if you attempt to create an encrypted installation without a passphrase, Lubuntu will be installed unencrypted. This is unlikely to be a problem for most users as disk encryption requires a passphrase for it to be effective. More information can be found here.
User password requirements
During testing, we discovered that it was possible to instruct Calamares to create the initial user account with a blank password. This was not the result of a bug in Calamares, but was rather due to incorrect configuration in Lubuntu. Due to the security implications of this, and because of a bug in XScreenSaver that could result in the user being locked out if the password is blank, we have chosen to require that some password be provided during the installation process, even if that password is only one character long. More details can be found in the official bug report.
If you fully understand what you are doing and do not want a password, there are several ways of disabling most or all password-based authentication in Lubuntu. These methods are documented on our Discourse forum here. We highly recommend that most users do not remove or otherwise disable their system’s password for security reasons.
PipeWire
Lubuntu previously used the PulseAudio audio system to provide rich audio functionality to our users. However, recently Ubuntu and its flavors have been gradually shifting to using the PipeWire audio server in place of PulseAudio. PipeWire offers several advantages over PulseAudio, including improved Bluetooth support, and more powerful management features for complex audio-related workloads. In order to offer these improved features to our users, Lubuntu has replaced the PulseAudio audio system with PipeWire in Lubuntu 23.04.
Screensaver
Since Lubuntu 20.04, the default screensaver has been “Flurry”. Due to reports of screensaver glitches on certain hardware, we have switched the default screensaver in Lubuntu to GL Matrix. This screensaver features a 3D “digital rain” effect that we have found to be aesthetically pleasing. If you have changed the screensaver yourself, you will probably not notice this change. If you find the new screensaver unappealing, you can change it back to the original “Flurry” screensaver (or to any of the other pre-installed screensavers) using the Screensaver application.
Picom
Lubuntu 22.10 and earlier run with no X compositor by default. (An X compositor is an application that can help provide various graphical effects and possibly smooth out screen tearing.) For those who benefited from X compositing, the Compton compositor was provided. We began also providing the Picom compositor (which is based on Compton but is more well-maintained) in Lubuntu 21.04. Starting with Lubuntu 23.04, we have switched entirely to Picom, and have enabled X compositing by default. This will allow effects like panel transparency to work out of the box rather than requiring that the compositor be manually enabled.
If you discover that X compositing is causing problems for you, or if you are experiencing significantly more screen tearing than in previous versions of Lubuntu, you can turn X compositing off by going to the Application Menu -> Preferences -> LXQt Settings -> Session Settings. You can then find and uncheck the “Picom (X compositor)” entry under “LXQt Modules”, and then click “Close”. X compositing should be disabled the next time you log in.
Artwork
We have refreshed the wallpaper, the default background for the login screen, the installer welcome image, and the installer slideshow for Lubuntu 23.04. This updated artwork was provided by one of our Lubuntu Members, Aaron Rainbolt.

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.
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.

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:
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.
Thanks to all the hard work from our contributors, Lubuntu 22.10 has been released. With the codename Kinetic Kudu, Lubuntu 22.10 is the 23rd release of Lubuntu, the ninth release of Lubuntu with LXQt as the default desktop environment.
Support lifespan
With 22.10 being an interim release, it will follow the standard non-LTS support period of nine months, which means 22.10 will be supported until July 2023. Our development focus going forward will be on 23.04 and future releases, so only critical bugfixes and security updates will be provided. We STRONGLY recommend upgrading to 23.04 once it is released, before 22.10 hits end of life. If this is not suitable for you, but you still enjoy new features on a regular basis, we would recommend staying on 22.04 LTS with Lubuntu’s Backports enabled.

Known Issues and Notable Changes
LXQt
A bug in LXQt results in duplicate menu entries for the Calamares installer, showing the following:
While either of these options work, we recommend using the desktop icon.
System Installer and Potential Instability
Lubuntu uses the Calamares system installer in place of the Ubiquity installer that most other flavors use. While we are ensuring 22.04 LTS’ Calamares follows the upstream LTS cycle, we decided to get ahead of the curve by shipping Calamares 3.3 Alpha 2 in 22.10.
Here are the factors that went into this decision:
Calamares is now a community project. We are committed to supporting the development of Calamares, and are actively involved in submitting bugs and testing feedback upstream. This is partially for the benefit of the Calamares project as well.
We now have an extremely thorough test suite covering a wide variety of install types. We have already tested for (and caught a few) bugs, and are confident this release will work for the vast majority of usecases extremely well.
An ongoing concern within the Ubuntu and Lubuntu communities has been the increased startup times for the Firefox web browser due to using the Snap package format instead of the traditional Debian-based package format used for the rest of the system. After careful consideration, taking into account the fast-paced technical improvements in modern web technology, the work required to keep Lubuntu users secure after the release, and Canonical’s commitment to Firefox as the default web browser for Ubuntu, we made the decision to keep this as-is.
That being said, the existing issues to watch out for include:
On a fresh boot of a Lubuntu system, the snap needs to decompress into memory the first time you run it. This will result in the browser launching noticeably slower.
Snaps ship with confinement enabled by default, in order to properly isolate the application from the rest of the system. While this eases the update process, if you need to pass through a device to Firefox (such as a smartcard), some manual work will be required.
We recommend consulting the Snapcraft Forums with any issues related to Snaps in general. More information on the Firefox snap specifically can be found here.

The default wallpaper for 22.10 is from one of our Lubuntu Members, Aaron Rainbolt:
Our greeter background also received an update this time and is from another Lubuntu member, sudodus:
Both artists entered our artwork contest and were selected for this release. We appreciate the exceptional art submissions from the community.
Ubuntu Pro Advertisement
It has come to our attention that Ubuntu Pro integration in apt is a bit too aggressive. We understand (and agree with some of) the concerns; at this current point in time, apt does not silence that message when using -qq either. We also understand that, with Canonical being the corporate sponsor of Ubuntu, they are entitled to put product advertisement in Ubuntu. The most reasonable compromise in our opinion is to allow the user to turn it off if they so desire, and Canonical (as noted in the bug report) is working on a better long-term solution for this.
We appreciate your patience while a reasonable solution is being worked out. If this message is preventing you from being productive, a temporary workaround is available here.
DKMS issues and workaround
Dynamic Kernel Module Support (DKMS) is a core package which handles the (low-level) loading of kernel modules once installed. An example of this would be installing Broadcom drivers, for specific network adapters. The DKMS version shipped by default in 22.10 has a bug causing third-party kernel modules to not be properly built or signed on Secure Boot systems, breaking support for hardware that requires those drivers if Secure Boot is enabled. If you are planning on installing Lubuntu offline, note that you will need to manually download and update to the fixed version.
The easiest way to work around this issue on Lubuntu Kinetic is to simply run sudo apt update && sudo apt full-upgrade before attempting to install third-party drivers on your system. If that’s not an option, and if you have familiarity with the command line, you can find a workaround in this bug report. Thank you to Aaron Rainbolt, one of our project members, for assisting with this.
We agree this bug is far from ideal. Had this issue been addressed a day or two sooner, 22.10 users would likely not come across this in the first place. That being said, the Ubuntu Release Team and Ubuntu Stable Release Updates Team made the informed decision to accept this immediately following 22.10’s finalization. If they did make the decision to accept it earlier, that would require last-minute re-verification of all ISOs, delaying 22.10’s release until tomorrow or later.
