Based on #347, this seems to be related to keys expiring and needing to be regenerated.

Was unable to reproduce with the latest build ISO, please make sure you have the latest build and ensure your time is set correctly too.

I am having the same issue. Time is correct on my esxi hosts but can't boot Ubuntu.

Ensured I downloaded the latest ISO and verified my time is correct (I have my time synced by GPS and distributed as stratum 1). Still unable to start Ubuntu, but the other distros I use work fine (AlmaLinux and Debian).

Great, I had refactored some of the CI a few weeks ago and I think it had broke the Ubuntu menu sigs, hopefully it's all fixed now.

I'm seeing this error currently. Disregard, it was an old image 🙃

Make sure time is correct on machine or try and validate that you can download the URL manually to a machine from your location.
