How do I interpret the output of `apt-get install -f` when trying to fix 'subprocess usr bin dpkg returned an error code 1'?

`apt-get install -f` attempts to fix broken dependencies. Carefully examine its output. It will list the packages it's trying to install or remove to resolve the issues. Pay attention to any error messages during this process. If it fails to resolve the dependencies, the output will provide clues about which packages are causing the problem.
