Ok, with a compliant EFI implementation, there's no reason that warm vs cold boot should be a factor either, but it's interesting to know and gives us a starting point.
If you've hit the problem so many times already, it seems likely that the problem will reproducible again on updates to the grub2-signed or shim-signed packages on your system. You may even be able to reproduce it manually by running 'efibootmgr' commands. Any reproducer that gets us some dmesg output would be helpful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786090 Title: Installation fails on HP T610 Plus Thin Client internal flash (EFI) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1786090/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
