Issue installing GStreamer

Hi,

I am following the steps in this walk through:

https://dev.px4.io/v1.9.0/en/simulation/gazebo.html

At “Prerequisites” I tried to install GStreamer 10.0 with this command

sudo apt-get install $(apt-cache --names-only search ^gstreamer1.0-* | awk '{ print $1 }' | grep -v   gstreamer1.0-hybris) -y

and I get the following error

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gstreamer1.0-python3-dbg-plugin-loader : Conflicts: gstreamer1.0-python3-plugin-loader but     1.14.5-0ubuntu1~18.04.1 is to be installed
