How to Fix APT Dependency Problems

APT is a package management system for Debian and other Linux distributions based on it, such as Ubuntu. For the most part, APT is easy to use for installing, removing, and updating packages.

With a normal APT install, using the apt-get command, a package will install without any problems. Installing a package in an APT repository will cause apt-get to automatically search for and install any necessary dependencies. In rare instances, often when you are mixing in third-party dependencies, there is a chance that apt-get may end up giving you an error telling you that a package installation could not be completed.

One of the most basic fixes for a problem like this is to run apt-get with “-f install”. The “-f” in this case stands for “fix broken”. APT will look for the best solution to resolve dependency problems. If you manually installed a package that had unmet dependencies, apt-get will install those dependencies, if possible. If it is not possible, it may simply remove the package that you installed in order to return sanity to your system.

Since removing the package you are trying to install may not be ideal, you might also try finding a repository that has the packages you need to satisfy the dependencies. Finally, if all else fails, you can attempt to satisfy the dependencies yourself, either by finding and installing the necessary packages, or by installing them from source and then creating “deb” packages for them.
