[Bug 1818663] [NEW] grub-emu is showing garbage text

[Joyce Babu]

Public bug reported:

I have a remote server running Ubuntu 18.04. When I ran apt upgrade
today, I got an error message from grub that original boot device is not
found, asking me to select the disk for installing boot loader. As per
the suggestion on the prompt, I selected all listed devices. But I still
got some error messages when installing the boot loader.

I tried to run grub-emu to verify that the bootloader is installed
correctly. I am getting the following screen, with lots of garbage text.

I am also attaching a copy of stdout redirected to a text file
