Ubunutu uses apt as it’s package manager , DPKG is a sort of low level package manager
sudo dpkg -i file.deb
APT ⇒ Advanced Packaged Tool
sudo apt install [package name]
In dpkg , we had to use the downloaded ,deb file , but for apt , we only need the library name . APT has a repository that is a collection of resources . So tool we want is taken from the repository , if incase the tool is absent from the repository , there is an alternate way , or there will be their repo list that we can add to the sources package list.

sudo apt purge package this will remove any user data that has been initiated.
