[Bug 1574104] Re: grub-install: error: cannot find EFI directory. package shim-signed 1.12+0.8-0ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Baruch]

FYI, I just gave up and changed system. (still some of the functionality
is lost)

I assume that the problem is the same (or very similar) and is related
to miss-understanding the current hardware configuration by grub or some
other configuration program.

The solution would probably be to copy whatever is one the old system
working so the change will be from an old working system to a new
working system. Breaking the boot should be prevented as first priority.

Only after the system boots properly the installer may offer improved
(but risky) boot options.

In short: don't break the computer when doing upgrades.
