Error while retrieving update information

[EXOgreen]

Noticed this in my logs while trying to find why my octoprint server died.

2018-10-28 15:20:17,381 - octoprint.plugins.softwareupdate - ERROR - Error while retrieving update information from plugin m73etaoverride

Traceback (most recent call last):

I don't think its my main issue but would be nice to know if your plugin has an update.
