RQT_GUI fails after upgrade

edit

After upgrading RQT_GUI now fails when run:

turtlebot@turtleVM:~$ rosrun rqt_gui rqt_gui 
WARNING: Package name "swig-wx" does not follow the naming conventions. It should start with a lower case letter and only contain lower case letters, digits and underscores.

Had this happen on a couple of machines, so quite sure it's not my setup. All packages are now upgraded and nothing is held back.

Seems like the recent upgrades broke a lot of things. Is this a weird situation due to ROS changing hands, or is it unrelated to that?

I've spent a day of leave just trying to get stuff working again, and looks like I won't have my turtlebot running for MakerFaire Adelaide.
