Comment 2 for bug 1732569

Thanks. But exact same problem after uninstalling caffeine and installing from the shop. Nothing happens when I click on the 'caffeine' and 'caffeine indicator' app buttons. When attempting to open from terminal I still receive this message:

caffeine
/usr/bin/caffeine:25: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import GObject, Gtk, GLib

Not sure what to do to fix
