Mavros: Mavros 1.2 not working properly URGENT

Issue details

I'm working with docker and I am using ros-melodic-mavros and ros-melodic-mavros-extras for controlling a PX4 iris drone. in the version 1.1 it worked just fine. I am controlling drones using Positiontarget to the topic : '/iris_{}/mavros/setpoint_raw/local but nothing happens in 1.2. There is no option to get a previous version from apt-get (why ?)
