If universal blue could not access its repositories, or git? I 'm just a begginer, so please excuse me, but if these images are updated daily, what happens at boot if you cant access these images? Is there an offline mode? what happens if there is a extended offline?
Thanks for reading, and your time…
If your computer does not have access to the internet, your computer will… stay the way it is.
Bluefin/Bazzite/UBlue/Fedora Atomic images live in the internet, but your installed system lives inside your computer. Your computer isn’t booting an image straight from the internet, but rather it pretty much pulls or copies these images into your computer. So your computer definitely can work offline for extended periods, it just won’t be able to download updates (and you won’t be able to browse the net!).

The images aren’t being generated/built by individual contributors. It’s automatically done daily by GitHub, which then hosts them at GitHub Container Repository (GHCR). So let’s say none of the contributors are able to access GitHub due to, e.g., power cut, internet outage, extended holidays, etc… the images will still be built by GitHub, following the set schedule and the set workflow. For example, Bluefin 40 is set to build every day at 16:40 UTC.
What might cause issues, such as delayed updates, would be GitHub outages, such as the incident with Actions from two days ago which affected 100% users who use Actions. But even then, the images built from before the outage are still available and working.
So if your concern is your system not booting if you don’t have internet, or if none of the Bluefin/UBlue contributors have internet, rest assured, it will boot up and function just fine.
