The way I solved this problem was simple. I had the option of installing Ubuntu 18.04 LTS, either using uefi mode or the device boot option (invoked through the BIOS startup by pressing ESC or F2). When I installed using uefi mode, I got this error. What I did next was to boot my USB through the device boot option in the BIOS startup and there was no aforementioned problem.
That is how I escaped the error. Hope this helps. -- 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
