Two days ago we did echo of a news item that stated that Ubuntu 22.04 it can be installed on the 4GB Raspberry Pi 2. Today we have to talk again about the operating system developed by Canonical, but this time about the kernel that it will use. Jammy Jellyfish, codenamed 22.04, will be an LTS version and, unsurprisingly, will use the latest Long Term Support kernel available, although at this time it has not received that label yet.
Linux 5.10 was an LTS version, but originally, if I remember correctly, it was only going to be supported for two years. When the community stepped up and ensured maintenance, support was expanded. With Linux 5.15 we are more or less in the same: it will be supported for longer than the normal versions, but at the moment not as much as 5.10. And in kernel.org It is not marked as LTS yet, just "Stable".
Ubuntu 22.04 is coming with GNOME 42
Right now, and if things don't change like they did with 5.10, Linux 5.15 will be supported until October 2023. A year and a half of support is not much for a Long Term Support version of Ubuntu, but the other option would be to use Linux 5.16 -5.17, supported around three months. Linux 5.15 was released in late October 2021, so it will not be a version of the most modern, but it was the most logical option and I do not think it surprised anyone.
Ubuntu 22.04 Jammy Jellyfish is currently in development, and the stable version will arrive on April 21st. Among its novelties, it is expected to use GNOME 42 (currently uses GNOME 40) and the latest version of libadwaita, but only a few applications will be fully adapted or re-based on GTK4. It will be supported for five years, so if they don't expand Linux 5.15 support, it might be a good idea to update the kernel in late 2023.
