> installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 10
This error status indicates there is a problem with debconf communication from within this package. grub-efi-amd64-signed does not invoke debconf itself, but does so via /usr/lib/grub/grub-multi-install. Can you run 'sudo /usr/lib/grub/grub-multi-install --target=x86_64-efi' manually and see if this command completes successfully? If it does not, please run 'sudo env DEBCONF_DEBUG=developer /usr/lib/grub/grub-multi-install --target=x86_64-efi' and paste the output. ** Changed in: shim-signed (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879948 Title: shim-signed installation focal fossa To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1879948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
