@nidhikamath2102 To clarify - the issue you were seeing (CRLF handling) is a different way to manifest the same error message. The PyCon sprints have revealed at least 3 ways that signing can fail:

1. The project drive is being mirrored on iCloud (this is #1831)
2. Git has core.autocrlf enabled (this ticket)
3. Running on an x86_64 machine with an older version of Xcode. (No ticket so far AFAIK; but someone was looking into this at the PyCon US sprints)
