Dear Phillip, you are totally right, and I fixed the explanation I got while trying to install already helped me to find out that I had to change a setting in my bios prior to install. That's exactly what I did. And everythign works well.
The problem here is related to the Modal that is attached in the screenshot of the second message that displays a close button which doesn't work. So it's a pure GUI design problem. The code behind the close button doesn't work and doesn't close the modal. And that's why I say install crash. The install doesn't work, it shoudl at least handle properly all the error case including the one when someone as EFI mode enabled and get the modal I got. But of course it's not a critical bug :-) just a user interface that fail to achieve his purpose. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626268 Title: install crash on thinkpad yoga with default bios settings with message: The 'grub-efi-amd64-signed' package failed to install into /target/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1626268/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
