The following packages have unmet dependencies:
libgstreamer-plugins-bad1.0-dev : Depends: libopencv-dev (>= 2.3.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I google the issue, and it appears that there is a rabbit whole of dependencies that ubuntu will not automatically install, related to libopencv-dev. Ubuntu 20.04: apt-get install libopencv-dev fails · Issue #3434 · appveyor/ci · GitHub
I was able to do this last year without issues, and im able to install inside a docker image but not in regular ubuntu desktop 20.04
