I have setup a fresh install of canvas on Linux using the quick start guide from the canvas-lms github repo. I created a course and added a single assignment and student. After entering a grade for the assignment, I click on export CSV under export on the grade page. After doing that, the export hangs (see the attached image export.png). Also, when I try to import a CSV file, canvas hangs again (see import.png). I have waited over an hour for both an import and export to complete in case it is just really slow, but no luck. Any help in correcting this problem is greatly appreciated.
