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
