Hi Steve, thanks for the response. I managed to get this working by coldbooting the machine, then ran:
sudo update-grub # this fixes the missing GRUB config Next I installed Vim -- APT figured out that shim-signed hadn't been configured, and retried. This time it succeeded! The machine came with Windows 7 Embedded, and I warm-booted into the installer (reboot from Windows, select "boot from USB stick" in the BIOS boot menu). I suspect the warm-booting may be a factor. Regardless, I will probably be doing a reinstall on this machine anyway and will update the ticket if I find out anything further. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786090 Title: Installation fails on HP T610 Plus Thin Client internal flash (EFI) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1786090/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
