Update Function Error
**Describe the bug**
Check for updates failed, 
"Metadata Fetch Failed"

**To Reproduce**
Steps to reproduce the behavior:
1. Open Gupax
2. Click on Gupax Tab
3. See error with update

**Screenshots**
If possible, add screenshots to help explain the bug.

**OS & Version:**
Linux Mint, Gupax v1.1.2

In short, auto update is not working.  If I update manually (download the latest bundle) I assume I will have to manually re-enter all settings?
