zsync from the "current" to "pending" daily iso and choice of UEFI in the virt-manager configuration for creating the KVM virtual machine has now booted successfully.
I do not know if it was the move to the pending iso or to using UEFI firmware that has made the difference, but it appears that the iso file now defaults to UEFI when booted directly in KVM, probably also in VirtualBox but I've not used VirtualBox so not sure about that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899370 Title: Can not install grub bootloader to /dev/sda To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1899370/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
