I just do pijul push ../new-repo inside the directory of an existing repo, and get this error message.

Can you give steps to reproduce from scratch, or is this from an old-ish repository (in which case it could be just a backwards-compatibility issue)?

Alright, I could reproduce, it does happen when you push from a channel that doesn’t exist in the other repository. Only the message is confusing, the error is legit.
