I received this error when I first logged into the Unity desktop along with several other alerts. The desktop appears to be functional despite these initial errors.

Disregard the last comment. This seemed to be corrected after I finished upgrading several packages, this morning. It looks like this, along with the other errors, was fixed. Thanks, Steve
