Installing apps using apt is as easy as: sudo apt install app_name

Installing apps using apt is as easy as: $ sudo apt install app_name

Uninstalling an app via apt is also super easy: $ sudo apt remove app_name

To upgrade your installed apps, you'll first need to update the app repository: $ sudo apt update

Once finished, you can update any apps that need updating with the following: $ sudo apt upgrade What if you want to update only a single app? No problem. $ sudo apt update app_name

Finally, let's say the app you want to install is not available in the Debian repository, but it is available as a .deb download. You can install it manually using dpkg, the system that apt helps manage: $ sudo dpkg -i app_name.deb To install an app: $ sudo dnf install app_name

Removing unwanted applications is just as easy. $ sudo dnf remove app_name

Updating apps: $ sudo dnf upgrade –refresh

The dnf (or yum) command is a front-end for the RPM packaging system. If you can't find an app in your software repository but you can find it for download directly from its vendor site, you can use dnf to manually install an .rpm file. $ sudo dnf install ./app_name.rpm
