[Bug 1782371] Re: 'grub-efi-amd64-signed' package failed to install into / target/. in Ubuntu 18.04

[Phillip Susi]

You have either a bad disk or more likely, a bad SATA cable, and also
probably some bad ram.  You should run the memtest option from the boot
menu and replace the faulty ram and SATA cable.
