Lubuntu 20.04 LTS is end of life with regard Lubuntu support, as was published on this site, and our main site
- Lubuntu 20.04 LTS is End of Life
- https://lubuntu.me/lubuntu-20-04-lts-end-of-life-and-current-support-statuses/
As was stated in those announcements
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.
FYI: You’ll also find the same on Ubuntu 20.04.5 announcements too; where only 3 years of support applied to flavors, which is why there is no mention of any flavor of Ubuntu 20.04 LTS mentioned on 20.04.6 announcements.
FYI: For anyone reading this message, and still on Lubuntu 22.10, please be aware you’re in the last hours of support for that release, which the EOL this Thursday.
