5 years ago Im not sure what to suggest. If Python, dbus and bluedot are all installed and accessible to the Pi user it would work without sudo (as running it on the Desktop version shows).
This isnt a bug with blue dot so I am going to close the issue.
Perhaps put a post on the Raspberry Pi forum?
I originally ran on a desktop version of raspbian and my app works OK by calling
I then did a clean build of raspbian lite, but the app fails unless I use sudo.
So there is a workaround, but I'd rather not be running with root permissions. Both builds were up-to-date Buster installations
