@oldfred; I understand your argument, but this doesn't take reality in account. I've looked for similar bugs (very likely duplicates of this one or visa versa) and there are more than 250 reports regarding grub failures at the end of the installation or upgrade. In theory you are right, in practice there are a lot of people who have troubles. The Linux kernel itself is full of "reality patches" that defy theory but work nevertheless.
Also take into account that the previous LTS installed fine and GRUB behaved as expected, even when dual-booting Windows 7. It's really easy to argue that this is a regression and should be fixed accordingly. In conclusion; when a large portion of your user-base is experiencing trouble where they don't expect it and/or had none before, it should be fixed. Especially when a fix is (easily) feasible and expands the use of Ubuntu and it derivatives considerably. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1771651 Title: The installation fails with a "GRUB installation failed" message.
