I don’t think that cleanup needs a private key.  In this case it was hung up on the “resume” stage of the backup.  If I give up on resuming, I could probably make it work by doing a cleanup before the full/incremental backup.  Then do a backup, get status, then cleanup again?  Cleanup is not a particularly time consuming operation.  BUT it just means that a particle update will never be resumed.

I hadn’t had problems with it, but multi-threading asynchronous actions are always problematic in Python.  One reason it is not my favorite development language.  Now that I have decent upload bandwidth from my ISP I do not have to try to optimize my transfers quite so much.

I will look forward to duplicity 3.X and re-evaluate then.
