To connect to a WPA encrypted wireless network on Ubuntu, you can follow these steps:

1. Click on the network icon in the top-right corner of the Ubuntu desktop. It looks like two arrows, one pointing up and one pointing down.
2. From the drop-down menu, select "Wi-Fi Settings" or "Wi-Fi Connections." This will open the network settings window.
3. In the network settings window, you will see a list of available wireless networks. Select the network you want to connect to and click on the "Connect" button.
4. A dialog box will appear asking for the network password. Enter the password for the WPA encrypted network.
5. If the password is correct, Ubuntu will attempt to connect to the wireless network. You may need to wait for a few moments while the connection is established.
6. Once the connection is successful, you should see a notification confirming the connection to the network.

That's it! You should now be connected to the WPA encrypted wireless network on Ubuntu.
