It's from here:

release-tools/run_release.py

Lines 960 to 965 in 2eea7cf

	stdin, stdout, stderr = client.exec_command(
	f"AUTH_INFO={auth_info} SIGSTORE_IDENTITY_TOKEN={identity_token} python3 add_to_pydotorg.py {db['release']}"
	)
	stderr_text = stderr.read().decode()
	if stderr_text:
	raise paramiko.SSHException(f"Failed to execute the command: {stderr_text}")

It wasn't really an error, but there was warning output on stderr, which the script interpreted as a terminal error.

I temporarily worked around it by commenting the guard out:

    stderr_text = stderr.read().decode()
    # if stderr_text:
    #     raise paramiko.SSHException(f"Failed to execute the command: {stderr_text}")

So this warning is a result of: sigstore/sigstore-python#1178

I'm not sure there's much we can do besides suppressing the stderr-to-error behavior for that specific command for now.
