I'm unable to reproduce this. I've tried upgrading from bionic to cosmic, or various partitioning set ups. Clearly there is something special about some set up that can cause this kind of issue, but I'm unsure what it could be.
Could you please tell us more about how your system was installed that could help reproducing the bug? - Is it upgraded from previous releases before the bionic -> cosmic upgrade? - Is there a special partitioning done? - Is "CSM" enabled in the BIOS with the UEFI mode? - Is there anything else you can say about the affected systems that could help us reproduce the issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1805490 Title: Grub2 Failed to install "efibootmgr failed to register the boot entry: Block device required."
