List Installed Packages with APT Repository

An APT repository is a collection of deb packages with metadata that is readable by the apt-* family of tools, namely, apt-get. Having an APT repository allows you to perform package installation, removal, upgrade, and other operations on individual packages or groups of packages.

You can use the apt to list your installed packages. To do this, run the command below:

apt list --installed

Example Output
