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:
libopencv-highgui4.2 : Depends: libopencv-videoio4.2 (= 4.2.0+dfsg-5+b2) but
it is not going to be installed
Depends: libopencv-imgcodecs4.2 (>= 4.2.0+dfsg) but it
is not going to be installed
E: Unable to correct problems, you have held broken packages.
so in essense it can't install because of libhdf5 which is currently
going through a transition: https://bugs.debian.org/954654 and we can
see that opencv wasn't rebiuld yet:
https://release.debian.org/transitions/html/auto-hdf5.html
* What outcome did you expect instead? Successful installation of the package.
Well no. If you want a stable system, use stable. If you want to be more up to date, use testing (where library transitions only happen en block). If you can live with packages being not installable from time to time, use unstable.
