tutrlesim_node fails due to incompatible Qt library

edit

Hello,

I am new to ros, and currently following the beginners tutorials. I installed ros melodic on Ubuntu 18.04 and followed the instructions up to section 7 in http://wiki.ros.org/ROS/Tutorials/UnderstandingNodes , where we need to activate the turtlesim node.

Running $ rosrun turtlesim turtlesim_node I get the following:

Cannot mix incompatible Qt library (version 0x50905) with this library (version 0x50c01) Aborted (core dumped)

rqt and rqt-common-plugins run fine (if that's informative in any way).

I could not find any information on why this might be the case or how to fix it, I would appreciate any ideas!
