Resetting the dpkg package database
Let’s use a simple command to reconfigure the dpkg database as this error can be caused due to some interruption during the installation. After running this command, try the installation and check whether you are facing the same error or not.
Force install package
Since dpkg was not the problem, try this command to forcibly install the problematic package. We are going to show you two different commands, which actually work similarly, will fix the broken dependencies to end the error.

This error is encountered when you are trying to add new software from the PPA (Personal Package Archive) repository. PPA is one of many ways used to install software on Linux system. First we will use the following command to update/synchronize the repository database, If the run completes without any errors, just proceed to the next step.
