Resolution

Verify the syntax in the "/etc/salt/minion" file are correct for any adjusted / modified entries.

Cause

Incorrect syntax used for adjusted entries in the "/etc/salt/minion" file.

Additional Information

One of the most common adjusted entries in the "/etc/salt/minion" file is to specify the DNS name for the Salt Master. There should be a space between the entries and the configured values, for example;

Correct:
master: salt.domain.com

Incorrect:
master:salt.domain.com
