[Bug 1798746] Re: Grub install fail - ubuntu 18.10

[Mathieu Trudel-Lapierre]

It appears grub-installer has failed because of an I/O error:

Oct 19 07:56:43 ubuntu ubiquity: grub-install : erreur : efibootmgr failed to register the boot entry: Erreur d'entrée/sortie.
Oct 19 07:56:43 ubuntu ubiquity: dpkg: error processing package grub-efi-amd64-signed (--configure):
Oct 19 07:56:43 ubuntu ubiquity:  installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

What kind of make/model is the machine you are installing on?
