clear the package cache upon completion

Clearing the package cache after completing a task is a good practice to free up disk space and ensure that the system is running efficiently.

In Linux, you can clear the package cache using the following command:

sudo apt-get clean

This command will remove all the packages that are no longer needed and clear the package cache.

In Windows, you can clear the package cache using the following steps:

1. Press the Windows key + R to open the Run dialog box.
2. Type "cleanmgr" and press Enter.
3. Select the drive where the package cache is stored (usually the C drive).
4. Check the box next to "Temporary files".
5. Click OK to start the cleanup process.

This will remove all the unnecessary files from the package cache and clear up disk space.
