@psusi you have answered (#37) to the OP and was right to set the report as 'invalid'. But a lot of dupes also exist; that is why some links have been added on top of the report to teach and educate users hiting such issue.

Setting it as 'incomplete' for now instead. ** Changed in: grub-installer (Ubuntu) Status: Invalid => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767703 Title: Calling 'apt-install grub-efi-amd64-signed' failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1767703/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
