To clean the cache using APT (Advanced Package Tool) on a Debian-based system, you can use the following command:
sudo apt-get clean
This command removes the .deb files for packages that are no longer installed on your system. These files are stored in the /var/cache/apt/archives/ directory.
For example, if you have previously installed and then removed several packages, running sudo apt-get clean will free up space by deleting the cached .deb files of those removed packages.
Additionally, if you want to remove unused packages and dependencies that are no longer needed, you can use:
sudo apt-get autoremove
And to update the package list and upgrade all installed packages to their latest versions, you can use:
sudo apt-get update && sudo apt-get upgrade
