Lubuntu 19.04 will be supported for 9 months, until January 2020. If you need Long Term Support, it is recommended you use Lubuntu 18.04 LTS instead (with LXDE), which will be supported for 3 years, until April 2021.
Older Lubuntu versions have reached their end of life and are not supported anymore, with the exception of 18.04, which is supported until April 2021, and 18.10, which is supported until July 2019.
The Lubuntu team has published a new version of their distribution. Lubuntu 19.04 provides nine months of support and ships with version 0.14.1 of the LXQt desktop environment. Unlike most other community flavours of Ubuntu which use the Ubiquity installer, Lubuntu uses the Calamares system installer. "This is the second Lubuntu release with LXQt as the main desktop environment. The Lubuntu project, in 18.10 and successive releases, will no longer support the LXDE desktop environment or tools in the Ubuntu archive, and will instead focus on the LXQt desktop environment. You can find the following major applications and toolkits installed by default in this release: LXQt 0.14.1; Qt 5.12.2; Mozilla Firefox 66, which will receive updates from the Ubuntu Security Team throughout the support cycle of the release; the LibreOffice 6.2.2 suite, with the Qt 5 frontend; VLC 3.0.6, for viewing media and listening to music; Featherpad 0.9.3, for notes and code editing; Discover Software Center 5.15.4, for an easy, graphical way to install and update software; the powerful and fast email client Trojitá 0.7 to get you to inbox zero in no time." Further details can be found in the project's release announcement. Download: lubuntu-19.04-desktop-amd64.iso (1,580MB, SHA256, signature, torrent, pkglist). Also available from OSDisc.
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.
This is the second Lubuntu release with LXQt as the main desktop environment.

You can find the following major applications and toolkits installed by default in this release:
- LXQt 0.14.1.
- Qt 5.12.2.
- Mozilla Firefox 66, which will receive updates from the Ubuntu Security Team throughout the support cycle of the release.

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.
Installer
Lubuntu uses the Calamares system installer in place of the Ubiquity installer that other flavors use. 19.04 ships with Calamares 3.2.4, but the important fixes have been cherry-picked from 3.2.5 for stability.
One notable feature in this release is working full-disk encryption. HUGE thanks to Jonathan Carter and Dmitry Shachnev for helping this land.
Note: In case of full-disk encryption, unlike the other flavors, Calamares does not create a separate, unencrypted /bootpartition. Therefore, LUKS 1 is the default, so that GRUB 2 can decrypt the partition. This is because GRUB 2 does not have support for LUKS 2 and Ubuntu switched to it by default in this release.
Some notable upstream features and fixes include:
- Easier customization of Calamares configurations using XDG configuration variables.
- The default fullscreen mode can now be set.
- RAID devices are now supported in the partitioner.
- The Austrian keymap is now properly handled.
For a full description of the new features and fixes, see the upstream announcements for 3.2.3 and 3.2.4.
Lastly, due to popular demand, the minimum RAM requirement has been lowered to 0.5 GB of RAM. (The RAM consumption is around 300-400 MB after startup).
