Thank you for filing this bug report. In my opinion, this bug is not caused by grub2, but by a configuration file in calamares-settings-ubuntu.
During installation the variable GRUB_DISTRIBUTOR in /etc/default/grub is set to 'Lubuntu 19.04' instead of `lsb_release -i -s 2> /dev/null || echo Debian`. #################################################### [Test Case] 1. Install Lubuntu 19.04 in EFI mode 2. Check that there is a boot entry named "ubuntu" with: sudo efibootmgr -v 3. Install Grub: sudo grub-install 4. Check that there are now two boot entries for Lubuntu: One named "ubuntu" with "File(\EFI\ubuntu\shimx64.efi)" and another named "lubuntu" with "File(\EFI\lubuntu\shimx64.efi)" 5. Edit /etc/default/grub and replace "GRUB_DISTRIBUTOR='Lubuntu 19.04'" with "GRUB_DISTRIBUTOR='bug'" 6. Reinstall Grub 7. Check that there are now three boot entries for Lubuntu: "ubuntu", "lubuntu", and "bug" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1833490 Title: lubuntu grub-install puts efi in the wrong directory - could create an unbootable state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calamares-settings-ubuntu/+bug/1833490/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
