Questions tagged [dependencies]
Use this tag when asking about managing and resolving dependencies. In Ubuntu most applications have dependencies, programs that they depend on to run correctly. This means that installing a package sometimes requires other packages to be installed, and removing packages will cause others to be removed by APT to prevent them from breaking.
