Thank you Mathieu, your suspicion was correct: After disabling that setting, the message on boot is gone, the latest versions of the packages work and I now see an "ubuntu" entry next to the NVMe entry in the UEFI boot device menu.
This resolves my immediate issue. I guess the actual problem is that I did not see an error message telling me that the "ubuntu" entry could not be written and that I'd have to modify my UEFI settings (or that this fallback was activated in the first place?). Do you need any more information from my side? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750351 Title: (Thinkpad T470) Boot loop after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1750351/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
