UPDATED (June 2021): 17-distro multi-boot image for Pinephone (incl. 3GiB variant)

[ikidd]

I've dd or etchered this a few times now, and I can't get gparted or kde partition manager to resize the btrfs partition. There's always bad tree blocks during the partition check prior to resizing that error it. I've done a scrub on the mounted partition and it says it fixes errors, but still fails.

Any ideas how to expand this so the operating systems on the image don't die within a few minutes from disk space issues?
