[Headless Ubuntu 16.04] - cannot start UMS GUI
Posted: Tue Oct 17, 2017 10:38 pm
Hi, I have installed UMS and have it working as a service - but the service appears to be scanning all folders despite setting folders in the relevant config file - I tried to fire up the GUI (After stopping the service to avoid conflicts) - but I get the following error
I have previously had success in starting the GUI - any ideas on how to fix this?
Code: Select all
