Description Of Issue
I figured out the problem because I understand Linux errors, but this should be fixed or at least users should be warned. I was setting up a CIFS share for my Roon database backup. The CIFS server account (a Macbook Pro) had a double quote in its automatically generated strong password. This kept failing with “Unidentified error.” I only figured out what might be wrong when I looked at the Roon server logs and found entries like the one below. Once I replaced the password by one with just alphanums, problem solved.
