It just occurs to me, I cannot switch Docker over to overlay2 as described at (Change the Docker storage backend) in order to be able to update Ubunto because switching to overlay will require ./launcher rebuild app which fails (unless switching it to overlay2 resolves the issue but that alone seems unlikely). So migrating to a new droplet seems like the only plausible way forward, though that will then presumably require DNS changes which is generally quite slow. Ugh.
