A little background on Linux Mint 22

Linux Mint 22 has finally been released and is immediately available for all existing Linux Mint enthusiasts and possible new Linux users. The regular Linux Mint, so not the LMDE Debian edition, is always based on the LTS releases of Ubuntu. The latest Ubuntu 24.04 Noble Numbat is a new LTS /  long-term support release that was released on April 25th, 2024. Linux Mint 24 is now also based on this newest Ubuntu 24.04 LTS foundation. Every Ubuntu LTS release receives 5 years of standard security maintenance. So, Ubuntu 24.04, and therefore Linux Mint 22 as well, will be supported till April 2029.

Linux Mint 22 is based on Linux kernel 6.8. All to-be-expected point releases (22.X) will have the benefit of the Hardware Enablement (HWE) kernel series. HWE makes sure that the newest devices will be better supported.

It is now also possible to Upgrade from Linux Mint 21.3 to 22. 

Note: In all situations where you do an upgrade or fresh install, it is always wise to perform a backup of your important personal data first, for example with the Vorta backup software.

Read my article “How to use Timeshift to backup and restore Linux Mint” for more information.
