Me to. I upgraded all out-of-date packages and the grub-efi-amd64-signed upgrade failed as shown above. This was an *upgrade* on bare metal (A Ryzen 3600 on a B550 motherboard) that had been booting just fine prior to this error. The '--no-nvram' work-around prevents the error but I have no idea if UEFI has been configured correctly.
FWIW, the efibootmgr program displays rational looking EFI entries: sudo efibootmgr BootCurrent: 0000 Timeout: 1 seconds BootOrder: 0000,0002 Boot0000* ubuntu Boot0002* Windows Boot Manager and the grub update does install new (or at least touch) the files in /boot/efi/EFI/ubuntu. I'm about to reboot this machine to see whether my home file server is borked or not :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872212 Title: grub-install: Operation not permitted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1872212/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
