[Bug 1765562] Re: 18.04 installer crashed on grub uefi install

[Mitch Rybczynski]

That is an excellent analysis of the root cause, however, the actual bug
is that the installer will EXIT INSTALLATION with no obvious cause when
this condition is present.

That is a bug, and a bad one at that, because it prevents your product
from being installed at all.  For someone who presumably wants to use
your product.

Closing bugs like this as invalid is a very good way to keep your
product out of the hands of users.  Which may be what you want.  Good
luck to you.
