I tried to upgrade to ubuntu 20 but the process somehow got stuck in the middle. Now I am finding it difficult to get back my system to normal as everything I install meets with the same output. For example, when I tried to install OpenCV I encountered the following error
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libopencv-contrib-dev : Depends: libopencv-calib3d-dev (= 4.2.0+dfsg-5)
Depends: libopencv-core-dev (= 4.2.0+dfsg-5)
Depends: libopencv-dnn-dev (= 4.2.0+dfsg-5) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
Even when I try sudo apt upgrade or sudo apt install -f i am facing the same error. I just don't know how to get rid of this.
I have looked into the following issue but no help to my question.
