I'm having trouble updating CKAN to 1.6.22 on Ubuntu 14.04. When I open up the gui I get a popup asking me if I'd like to install the update, if I press the install button the popup goes away but nothing happens. Opening up the gui just repeats the process, no actual update. I've tried downloading and replacing with the newest EXE and going through the install process again but that doesn't seem to do anything.
