Ubuntu 20.04 is releasing today and you should learn about upgrading to Ubuntu 20.04 from older supported Ubuntu versions. It comes with a lot of new packages and major software upgrades, including the latest versions of OpenJDK, GCC, Python, Ruby, and PHP. This release is based on the Linux 5.4 LTS kernel and adds support for new hardware and filesystems. The desktop edition comes with GNOME 3.36 and a new default theme called Yaru.
Before you upgrade (whenever you choose to) I recommend creating a backup of any important files and system settings, dotfiles, and any critical content. Keep some ‘rescue’ media to hand should things go wrong, too. If you upgrade to 20.04 before April 23 you do NOT need to reinstall anything to get the ‘final version once it’s released. Just keep installing any (and all) pending software updates and you’re good to go.
Upgrade to Ubuntu 20.04
Step 1. First, before you start installing any package on your Ubuntu server, we always recommend making sure that all system packages are updated.
sudo apt update sudo apt upgrade sudo apt dist-upgrade
Step 2. Upgrade to Ubuntu 20.04 LTS (Focal Fossa).
Upgrading to the latest Ubuntu version is a pretty straightforward process. You can upgrade either from the command line with
do-release-upgrade or using the GUI update tool.
Start the upgrade process by entering:
sudo apt install update-manager-core sudo do-release-upgrade -d
When the upgrade process is complete and assuming all went well, you’ll be asked to reboot your machine. Type
y to continue:
System upgrade is complete. Restart required To finish the upgrade, a restart is required. If you select 'y' the system will be restarted. Continue [yN] y
Wait for a few moments until your system boots up and log in. You can also check the Ubuntu version by entering the following command:
$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04 LTS Release: 20.04 Codename: focal
