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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1765562 Title: 18.04 installer crashed on grub uefi install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1765562/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
