Failure when booting Ububtu 20.04 in Secure Boot
Hi, @longpanda - Sorry I didn't respond back earlier. I didn't get an email that you had asked your question.

The same error occurs without persistence enabled. I put an Ubuntu 18.04 LiveUSB ISO image onto my Ventoy USB drive, and saw the same error pop up.

I found something new to add about this issue, though.

While I saw the same Verification failed: (0x1A) Security Violation MOK error occur for both the 20.04 persistent image and the 18.04 non-persistent image, I tried something I wouldn't normally do: I decided to try hitting "ESC" each time I saw the MOK error, and both images would successfully boot to Ubuntu after the 4th failure message > ESC key press.
