FYI we have been getting some reports of users mistakenly doing a full distro upgrade to their system, this will still brick your OS as it pulls the full ubuntu upgrade to 22.04, which our board is not designed for. 

The base system will still be 20.04, and you should only do apt update/upgrade...do NOT do a full dist upgrade if the OS prompts you to upgrade to 22.04.

The fix we implemented is to only do base system updates/security updates to the current 20.04 and 5.15.x kernel which the Apollo will remain on for the foreseeable future.
