If you use Bazzite, Bluefin, Aurora, or any other Universal Blue image (including our toolboxes) then you need to follow the instructions in this announcement in order to ensure that your device is getting updates. We were rotating our cosign keypairs this morning, which is the method that we use to...
This is a good tip but is there not a more reliable way for the issue to be communicated to users? I suspect many people are going to be stuck on the pre-error version of Bluefin, unaware that updating is broken.
It has been asked on the forum. Idk if they will consider implementing some type of notification for critical issues on the OS itself.
Edit: they are working on a solution
