Hello,under ubuntu 18.04,when following this link
to install gstreamer,I got this 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 1.14.1-1~ubuntu18.04.1 is to be installed gstreamer1.0-python3-plugin-loader : Conflicts: gstreamer1.0-python3-dbg-plugin-loader but 1.14.1-1~ubuntu18.04.1 is to be installed E: Unable to correct problems, you have held broken packages.
make px4_sitl gazebo_typhoon_h480
this error will come up:
INFO [px4] Startup script returned successfully pxh> [Wrn] [msgs.cc:1852] Conversion of sensor type[sonar] not supported. [Err] [Plugin.hh:180] Failed to load plugin libgazebo_video_stream_widget.so: libgazebo_video_stream_widget.so: cannot open shared object file: No such file or directory [Err] [MainWindow.cc:2094] Unable to create gui overlay plugin with filename[libgazebo_video_stream_widget.so] [Wrn] [msgs.cc:1852] Conversion of sensor type[sonar] not supported.

gazebo simulator worked,but video streaming doesn’t,and it seems like a gstreamer install problem,anyone know how to fix this problem?Thanks.
