[Bug 1781642] [NEW] ubuntu 18.04lts desktop crashes (without updates during installation?)

[Homeless Gamer]

Public bug reported:

Using the ubuntu 18 lts desktop installer to install a slim/lightweight
ubuntu to my hdd: no updates and/or internet connection during
installation.

Installation crashes: "grub-efi-amd64-signed failed installation
/target/..."


Google says, it works if "update packages during installation" is checked.
