[Bug 1786090] Re: Installation fails on HP T610 Plus Thin Client internal flash (EFI)

[Steve Langasek]

Can you attach the output of the 'dmesg' command when this happens?
This really shouldn't happen at all, but maybe we can get some more
verbose information from the kernel about what's failing.

Also, if grub-install succeeded for you once following a reboot, it
seems that it's not *impossible* for Ubuntu to write to the nvram... but
it definitely isn't working consistently.

Title:
  Installation fails on HP T610 Plus Thin Client internal flash (EFI)

Status in grub-installer package in Ubuntu:
  New

  Incomplete

Bug description:
  I tried to install Xubunti 18.04.1 LTS on a HP T610 Plus thin client
  with the 1.20 Rev A BIOS (recently upgraded from 1.16 Rev A).

  The installation proceeded normally until the bootloader was installed
  -- grub-install failed.

  I ran grub-install a second time from a console and got the same error
  as seen in the installer:

  <pre>$ sudo chroot /target grub-install /dev/sda
  Installing for x86_64-efi platform.
  Could not delete variable: Invalid argument
  grub-install: error: efibootmgr failed to register the boot entry: Block device required.
  </pre>
