I think commen #6 is correct: it looks the 2018 patch introduced the issue for us, but the patch is originally for "initrd-less boot capabilities." and here we do need the initramfs file.
I guess the patch "ubuntu-add-initrd-less-boot-fallback.patch" is not included into the grub shipped in the 20.04 .iso file ubuntu-20.04-live- server-amd64.iso, but somehow it's included into the grub shipped in the cloud-image? If so, I guess we can fix this bug by removing the patch for cloud-image? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870189 Title: initramfs does not get loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1870189/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
