Ubuntu 22.04 Upgrade is one of the most important updates for Linux users who want better security, improved performance, and long-term support. Since Ubuntu 22.04 LTS includes newer kernels, updated development tools, and enhanced desktop features, many administrators and developers are moving to this stable release.
In this guide, you will learn how to safely upgrade Ubuntu systems from Ubuntu 20.04 or Ubuntu 21.10 to Ubuntu 22.04 LTS.
Ubuntu 22.04 LTS, also known as Jammy Jellyfish, delivers five years of official support. Additionally, it introduces updated versions of Python, OpenSSL, PHP, GCC, and Ruby. The release also includes the Linux 5.15 LTS kernel, which improves hardware compatibility and system stability.
Desktop users benefit from GNOME 42, smoother interface performance, and new screenshot tools. Therefore, upgrading helps both desktop and server environments stay modern and secure.
Before starting the Ubuntu 22.04 Upgrade process, create a complete backup of your important files. If you use a virtual machine, take a snapshot so you can quickly restore the system if anything fails.
Next, verify that your internet connection works correctly and confirm that you have sudo privileges.
You should also check for held packages because they can interrupt the upgrade:
sudo apt-mark showhold
If Ubuntu lists any held packages, remove the hold status before continuing:
sudo apt-mark unhold package_name
Afterward, update all installed packages:
sudo apt update sudo apt upgrade sudo apt full-upgrade
Finally, remove unnecessary dependencies and outdated kernels:
sudo apt --purge autoremove
Ubuntu includes a built-in release upgrade utility called do-release-upgrade. In most cases, the package already exists on the system. However, if it is missing, install it manually:
sudo apt install update-manager-core
Next, launch the upgrade process:
sudo do-release-upgrade
The tool automatically updates repository sources and downloads the required packages for Ubuntu 22.04 LTS.
During the process, Ubuntu may ask whether it should restart services automatically or replace modified configuration files. Read each prompt carefully before selecting an option.
If you connect through SSH, temporarily allow port 1022 to avoid connection interruptions:
sudo iptables -I INPUT -p tcp --dport 1022 -j ACCEPT
Because the upgrade may take some time, ensure your device stays powered on throughout the installation.
Once the installation finishes, reboot the system:
sudo reboot
After login, verify the installed Ubuntu version:
lsb_release -a
The output should display Ubuntu 22.04 LTS with the codename Jammy.
Ubuntu 22.04 Upgrade provides a stable and secure platform for developers, businesses, and Linux enthusiasts. With updated packages, improved kernel support, and long-term maintenance, Ubuntu 22.04 remains one of the best Linux releases for production systems. By following proper backup and upgrade procedures, you can complete the migration safely and avoid unnecessary downtime.
