In Debian package management, which command helps to resolve and fix broken dependencies?

The command that helps to resolve and fix broken dependencies in Debian package management is apt-get install -f. This command is specifically designed to fix any package dependencies that are not satisfied or are broken. When you run this command, it attempts to correct a system with broken dependencies in place by installing the necessary packages to satisfy the dependencies.

Using apt-get install -f is beneficial when you may have interrupted installations or when package states become inconsistent. It effectively tells the package manager to attempt to fix any dependency issues that exist by fetching and installing the required packages from the repositories.

In contrast, dpkg --fix-broken is a similar command that operates at a lower level, primarily using dpkg, which deals with packages directly. While it can address some issues, apt-get is generally preferred because it handles dependency resolution more efficiently and comprehensively.

The other options, apt-get upgrade and apt-get clean, serve different purposes. Apt-get upgrade is used to update all installed packages to their latest versions but does not specifically resolve broken dependencies. Apt-get clean is used to clean up the local repository of retrieved package files, helping to free up space but not addressing any dependency issues.

Overall, apt-get install -f is the most trusted method within the debian package
