我尝试升级到 ubuntu 20，但不知何故，升级过程卡在了中间。现在我发现很难让我的系统恢复正常，因为我安装的所有内容都出现相同的输出。例如，当我尝试安装 OpenCV 时，我遇到了以下错误
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).
即使我尝试了sudo apt upgrade，还是 sudo apt install -f会遇到同样的错误。我只是不知道如何摆脱它。
我调查了以下内容问题但对我的问题没有帮助。
