Ubuntu 20.04.5 LTS Released With Hardware Enablement Stack Backported From 22.04
Ubuntu 20.04.5 LTS collects up all the stable release updates to this point to make it easier to deploy fresh 20.04 LTS installs with all available SRUs included. In addition, Ubuntu 20.04.5 LTS features the newest hardware enablement "HWE" stack that is backported from the newer Ubuntu series. In the case of 20.04.5 LTS, it pulls in the Linux kernel and related components from Ubuntu 22.04 LTS, meaning there is now Linux 5.15 LTS available, Mesa 22.0 for newer graphics driver support, and other related package updates.
Yesterday there were last-minute rebuilds of Ubuntu 20.04.5 LTS images due to a NVIDIA driver issue, but Canonical engineers got it sorted out in time for this release on-schedule.
