What is "SwiftPM.SPMRepositoryError error 5"?

Question

I've searched Apple's documentation, open source projects, and Google, and I cannot seem to find any information about SwiftPM.SPMRepositoryError error 5. Heck, I can't even find information about SwiftPM.SPMRepositoryError.

Does anyone know of documentation for this error or the error codes?

What worked for me was switching to ED25519 key.

I think this is happening now because of the effort to improve Git protocol security on GitHub. You can read more about it here: https://github.blog/2021-09-01-improving-git-protocol-security-github/

There you can see the timeline. The final step was put into motion on Mar 15, 2022 (coincidentally that was just two days before your question)

Changes made permanent.
We’ll permanently stop accepting DSA keys. RSA keys uploaded after the cut-off point above will work only with SHA-2 signatures (but again, RSA keys uploaded before this date will continue to work with SHA-1). The deprecated MACs, ciphers, and unencrypted Git protocol will be permanently disabled.
