I get these errors. I disabled Secure Boot in BIOS but still same. I'm installing Ubuntu Server into Dell Precision Tower 3640. Refer to photo here.

  • If you don't need it then just disable TPM. – ChanganAuto Nov 09 '21 at 09:35
  • The TPM error cleared, but others remaining. And I still can't boot into the installer. Trying to flash the USB drive once again. – willyouth Nov 09 '21 at 09:46
  • Yes, good move. You should also consider updating UEFI if there's an update available. – ChanganAuto Nov 09 '21 at 09:48

    Found out that the error is negligible and doesn’t affect the boot process. It’s a graphic issue which causes the screen to hang there. Tried it on my other computer just now, its working fine. – willyouth Nov 09 '21 at 10:31
  • Also look at https://bugzilla.kernel.org/show_bug.cgi?id=213323. – 0andriy Dec 12 '22 at 15:13
