The pkcon command is a powerful tool for managing packages on systems that use the PackageKit framework, commonly found in distributions like Fedora and its derivatives. It provides a user-friendly interface for common package operations directly from the command line.

Refresh Package Cache

Before installing or updating software, it's crucial to ensure your system has the latest information about available packages and their versions. The pkcon refresh command achieves this by updating the local cache of package repositories.

# To update cached information about available updates:
pkcon refresh

Update Installed Packages

Once your package cache is up-to-date, you can proceed to update all installed packages to their latest available versions. This is a fundamental step in maintaining system security and stability.

# To update installed packages:
