Step 1. Open the Ubuntu Terminal.

You can do this by navigating the applications menu or using the keyboard shortcut Ctrl + Alt + T.

Step 2. Update your system with the command below:

That ensures all system packages are up-to-date, the core operating system, the Kernel, and applications installed via apt or software center.

Step 3. Make sure you have the universe repository enabled on your system. You can easily do that with the command below:

sudo add-apt-repository universe

If you get an output like that shown on the image above, then, Universe repository is already enabled on your system.

The installation process shouldn’t take a long time, but that depends entirely on your Internet speed.

Upon completing the command execution, you will see a list of all available extensions, as shown in the image above.

Step 7. Installing a single extension.

To install a single extension is quite easy. Use the apt install command with the extension name, as shown on the Terminal. For example, to install the first extension listed on the Image above, we will execute the command below:

Step 8. Install all available extensions.

If you want to install all of the extensions listed by the search command, execute the command below on your Terminal.

It might take quite a while to execute as it finds and installs all available extensions for the Gnome Tweak Tool.

Click on the Appearance menu located on the left panel. Under the Themes section, click on the dropdown box next to the Applications name. Select the option Adawaita-dark or Yaru-dark to set a dark theme. You will immediately see the Gnome Tweaks app switch to a dark mode. That’s’ so cool! If you don’t want a dark theme, there are many other options you can choose from.
