Schedule Conflicts:
Unable to access MythTV Perl API. Try with --verbose to find out why.

I get most of the status for the server, but I don’t get the read outs of the conflicts because of the error.

What happens (as far as I understand it) is that when the cronjob generates the motd, it runs as root, and root does not have a link to the mythtv config, so it can’t get the data from the database.  So, to get around this, we need to create a link in /root/.mythtv/ to the config.xml file for the server.  For me, this runs from my home directory /home/thomas/.mythtv/config.xml so:

sudo ln -s /home/thomas/.mythtv/config.xml /root/config.xml

Once you make this change, the next time the cronjob runs it should populate the motd correctly.

Notes: I’m running this server on Ubuntu 8.04.02 64-bit.
