Ubuntu solves the package dependency:

The following errors occur:

This is because the system cannot meet your requirements. This version may contain software you need.

E: the error cannot be corrected because some software packages are required to maintain the status quo, that is, they destroy the dependency between software packages.

I checked it online mainly because of version issues. The old package must be uninstalled when the new package is installed. However, the next package may need to be installed when the new package is uninstalled. Therefore, dependencies are generated (I personally understand, I don't know if it is correct)

After a long tangle, I suddenly find that every time this problem occurs, many packages are installed at the same time. For example, this installation command is

Sudo apt-get install build-essential libgtk2.0-dev libjpeg62-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy libtbb-dev libeigen2-dev yasm libfaac-dev libopencore-amrnb-lidev bopencore -amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev

So I split the above command into one package for installation, and I found that the installation was successful. In this way, he will unmount some files.
