I am still having this issue every time you upgrade install-grub
The solution is to replace the line 121 in the script to
awk -e '/EFI\\x20\(FAT-12\/16\/32\)|EFI\\x20System|BIOS\\x20boot/ {print $2}' | tr -s '\n'); do
Mind the |BIOS\\x20boot extra piece. Before and after the change I got this:
[alex@alex-b450aoruselite ~]$ sudo install-grub
