Status changed to 'Confirmed' because the bug affects multiple users.

[themusicgod1 (themusicgod1)]

at least in 17.10, this error consistently results from not having location services enabled. This was likely true for 17.04/16.10.

Perhaps an update to the error message suggesting as much might be warranted?

[themusicgod1 (themusicgod1)]

As of bionic, there's no error message at least first run & redshift Just Works[tm]. Location services must be working?

[themusicgod1 (themusicgod1)]

Disabling location settings in the location menu recreates this : once you disable it, redshift errors out like this and refuses to run.
