Grub version error.

[davidtj]

A very basic question I did an upgrade and get the message that i'm on V7.4-19 and support has stopped. So now need to upgrade to latest V8 and I have done as a pre-requisite the test pve7to8 and get the message "WARN: System booted in uefi mode but grub-efi-amd64 meta-package not installed, new grub versions will not be installed to /boot/efi! Install grub-efi-amd64" - do I therefore do a apt install grub-efi-amd64 from the shell?
I cant recall what selection I made when doing original install, but pretty sure kept it totally default/basic. Appreciate any help - trying to avoid breaking the system.

Yes.

If you also purge the grub-pc package, run update-grub once again to create the grub.cfg. I just updated a couple of machines yesterday and ran into this problem.

Thanks are the commands therefore:

apt install grub-efi-amd64
sudo apt-get purge grub-pc
sudo update-grub

In that order. Really appreciate as Im a newbie to this kind of thing.

tried "apt-get purge grub-pc" Which wanted to remove bootable disk so I aborted.....

What seemed to do the job was following commands:
[ -d /sys/firmware/efi ] && echo "UEFI mode" || echo "Legacy mode"
apt install grub-efi-amd64
apt purge grub-pc
update-grub
