@rohbotics same issue!
I got 3.3.0 on rpi3.
More specific is the dependency for cv_bridge be compatible with 3.3.0
But I think OSRF friends are busy developing ROS2, I ever build from source cv_bridge with OpenCV3.2.0 to get libcv_bridge.so (kinetic default), then pkg-config with 3.3.0 try to use other dnn functions, but got no luck.
The terminal freeze when i’m compiling the application code.
Ooops, sorry in Chinese.
Anyone got good idea? Let’s make it work together
