GNU Parted 2.3 I don't think this is the same issue as #820723; I've successfully performed grub upgrades several times, but a recent grub package started producing this behavior. My system still boots at the moment; the package simply will not upgrade.
Here's my partition scheme (which I created manually, not using the installer directly) /dev/sda1 is my UEFI EPS partition. I created the partitions manually during installation to work around the issues in #769669 (partman creates an illegal FAT16 EPS partition). /dev/sda2 is my btrfs root partition. $ sudo parted /dev/sda Using /dev/sda Welcome to GNU Parted!
