But before we start, I want to inform you that you cannot directly upgrade to Ubuntu 20.04 from Ubuntu 16.04, 18.10 and 19.04. You can only use Ubuntu 18.04 or Ubuntu 19.10 to upgrade.
One more thing, this article focuses on upgrading Ubuntu using GUI (user interface). However, if you prefer to use the terminal or you are an SA (system administrator), you can also upgrade Ubuntu using the command line.
What does Ubuntu 20.04 have?
Ubuntu 20.04 has many notable changes in system, user interface and accompanying software.
This version used the 5.4 kernel. This will help improve hardware performance. Ubuntu developers have also enabled support for WireGuard (secure VPN technology) and built-in Livepatch (for kernel updates without rebooting).
Kernel and initramfs compression algorithm changed to lz4 to deliver faster boot times.
And that includes other UI changes like new login screen, new lock screen, new wallpaper, the color of folder icons has also changed.
One feature that Ubuntu users have been waiting a long time to experience is Dark mode.
Ubuntu’s software store is now a Snap-based version. This doesn’t affect everything as it’s still a basic GNOME-based tool, but packaged in Snap format.
