The error in your log is: Setting up shim-signed (1.34.9+13-0ubuntu2) ... Installing for x86_64-efi platform. Could not delete variable: Invalid argument grub-install: error: efibootmgr failed to register the boot entry: Block device required. ESC[1mdpkg:ESC[0m error processing package shim-signed (--configure): installed shim-signed package post-installation script subprocess returned error exit status 1
Your attached fstab information looks reasonable. /dev/sda1 486456 4880 481576 2% /boot/efi and your bug report shows that shim-signed had clearly been successfully installed previously, and that your system is booted in EFI mode. However, something between grub and efibootmgr has failed when trying to access / update your firmware variables. Reassigning to grub. ** Package changed: shim-signed (Ubuntu) => grub2 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766729 Title: package shim-signed 1.34.9+13-0ubuntu2 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1766729/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
