Yes, I get that but it still looks like a packaging bug if dpkg installs flash-kernel first and /boot is not populated with existing initrds; one could easily see this happen in a debootstrap. Is the "liveness" of the chroot what's tripping up flash-kernel? We currently run inside a chroot which mounts /dev /proc /run and /sys; we could drop those but it also seems reasonable to have flash-kernel not expect existing initrds? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918427 Title: curtin: install flash-kernel in arm64 UEFI unexpected To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1918427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
