Public bug reported: I experienced this bug when installing Ubuntu 20.04 with EFI. I am able to reproduce this bug on other computers. This bug only occurs when I install Ubuntu without network connection. When the computer is connected to a network this bug does not occur. I checked this on several computers and I was able to reproduce it.
