Installing Software Updates

Once you have identified the available updates, you can proceed with their installation. Here’s how:

1. Install All Updates: To install all available updates in one go, run the following command:

“`
sudo apt upgrade
“`

Handling Update Errors

Occasionally, you may encounter errors during the software update process. Here are some common errors and their solutions:

Scheduling Automatic Updates

To ensure that your system remains up-to-date without manual intervention, you can schedule automatic updates. Here’s how:

4. Save and Exit: Once you have made the necessary changes, save the file and exit the text editor.
