How to set up Ubuntu 20.04 laptop

Recently, I could not boot into my laptop because the laptop ran out of space. No attempt to resize sda was successful. Since the disk was encrypted, I could not even access my data files.

I had to wipe out my current installation of Ubuntu 18.10 and install Ubuntu 20.04

Here are the steps I had to take to get the laptop ready.

0. Create Ubuntu iso image CD and install Ubuntu 20.04 onto laptop.

1. Install Mullvad VPN client

2. Customize Firefox browser
