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 sign our images. 

During this process I made a critical error which has resulted in forcing you to take manual steps to migrate to our newly signed images. 

- All existing Universal Blue images BEFORE 2024-07-02 will need to issue the commands below in order to receive future updates, your device will reject future updates unless this action is undertaken.
This incident does not mean that there was a security breach, quite the opposite, in fact. It means the protections and checks we've built into the operating system are working and they'll refuse to accept an update signed by an unknown key. 

- The installation on your device is fine, upgrades just won’t work. But you do need to follow the instructions below in order to get updates.

- All the Universal Blue images and ISOs have been updated to the new key, we strongly recommend replacing any downloaded ISOs with the new ones to avoid having to do this on new installations. 

I deeply apologize for this, I take full personal responsibility as the error was completely mine, from both a technical and process standpoint. I know this shakes the amount of trust we’ve built up over the past three years, so there’s no easy way to say it other than by being transparent about the mistakes.

Huge thanks to p5, m2, bsherman, antheas, hikariknight, and eyecantcu for mitigating my mistake as best they could.
