Canonical is delaying the release of Ubuntu 22.04.2 by two weeks until February 23 after it encountered some issues with the new Hardware Enablement (HWE) kernel that supports new hardware with the current long-term support edition of the operating system. Designed to work. People running Ubuntu 22.04 are not affected, but those waiting for a point release with the HWE kernel will have to wait a little longer.
While trying to port the Linux 5.19 kernel that shipped with Ubuntu 22.10 to Ubuntu 22.04, Canonical ran into some unexpected compiler and DKMS issues that slowed down the process. By pushing the release forward by two weeks, the company hopes to test the new kernel some more to ensure stability, after all, Ubuntu 22.04 is an LTS release and users expect stability.
In addition to the kernel issues, Canonical also made shim 15.7 (which provides UEFI support) available for upload in their archive. Since this version revokes existing keys, the company wants to fix things so that existing installations continue to work properly. As part of this process, all kernels that will be in Ubuntu 22.04.2 need to be rebuilt. The extra time will allow this task to be done more easily.
All this delay means you’ll have to wait a little longer for the new Ubuntu 22.04.2 ISOs to become available. If you already run Ubuntu 22.04, just keep applying any updates available to stay up to date.
