What is APT?

Installing Software Using APT

Step 1: Update Your Package List

Before installing anything, it’s a good idea to update the package list. This ensures that Ubuntu knows about the latest versions of software available.

Open your terminal and type:

sudo apt update

• sudo: Gives you administrative privileges.
• apt update: Refreshes the list of available packages.

Step 2: Install the Software

To install a package, use the following command:

sudo apt install package_name

Replace package_name with the name of the software you want to install. For example, to install VLC, the media player, you’d type:

sudo apt install vlc

Tips for Installing Software

• If you aren’t sure about the exact name of the package, try searching for it first:

  apt search package_name

This will show a list of similar packages, so you can pick the right one.

Removing Software Using APT

Uninstalling software is just as simple as installing it. Here’s how you do it.

Step 1: Remove the Software

To remove a package, use the command:

sudo apt remove package_name

For example, to remove VLC:

sudo apt remove vlc

Step 2: Clean Up Unused Packages

When you uninstall software, some unused dependencies (extra packages) might remain. To clean them up, run:

sudo apt autoremove

This will remove any packages that were installed alongside the software but are no longer needed.

Common Mistakes to Avoid

• Forgetting to update the package list: Always run sudo apt update before installing or removing software.
• Misspelling the package name: If the package name is wrong, APT won’t find it. Double-check the name or use apt search to be sure.
