Redshift - Enable location services on ubuntu 16.04

I have a problem with Redshift. It doesn't get the location from my geolocation provider 'geoclue'. The problem was more noticeable when I tried to use Maps app which said I should enable location services in order to be located. I just can't find any settings regarding this. Anyone? Thanks

P.S. Clicking on button "Location Settings" does nothing

From the terminal try:

redshift -l list

You should see: geoclue2

Try changing location provider to geoclue2

If you have redshift config file under ~/.config/redshift.conf this can be changed there.

I use Ubuntu Gnome 16.04 but should work the same:
Settings > Privacy > Location services > on
works for me, although the location accuracy is not perfect!
