Use the "darktable" snap instead. Both snaps are the same, and maintained by the same person, but "darktable-kyrofa" will eventually no longer be updated.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
