Comment 14 for bug 1617535

Using the:

$ gsettings set com.ubuntu.geoip geoip-url https://freegeoip.net/xml/

Appears to work well enough after initial testing.

1) $ gsettings set com.canonical.indicator.datetime show-auto-detected-location true
shows my correct location

2) apt install geoclue-examples
   and then geoclue-test-gui
   . . . seems to show correct information, as well.

The freegeoip service appears to be well-maintained. Perhaps this is a service that canonical / ubuntu could move to / could support, as well.
