![]() It is also a good choice for systems under the control of an Infrastructure as Code (IaC) application, like Terraform or Chef. This method is a better choice if the system is running a much older release of Ubuntu or if the configuration is very convoluted.It is easy to forget to port over important applications and application data. This method takes a lot more effort and is more error prone.Old packages and unwanted files are not copied over. The configuration tends to be cleaner.It is easier to troubleshoot any problems because there are fewer dependencies.The pros and cons of a clean install are as follows: After the new node is fully configured and operational, the old node is decommissioned. All necessary applications are reinstalled and the backed-up data from the old node is copied over. This approach deploys a brand new Linode running the Ubuntu 22.04 release. The clean install method takes the opposite approach to the inline upgrade. It is difficult to predict how the upgrade might affect these programs. An inline upgrade might run into more problems when the system configuration is complicated or includes in-house applications.Īlthough this process upgrades the Ubuntu operating system and most common programs, it does not necessarily upgrade every application. This method is recommended if the system is only one release behind and is mainly running a widely used and tested configuration such as a LAMP stack.This includes unnecessary or outdated packages, patches, and data. This method of upgrading tends to retain “digital residue”.There is also a greater chance of data corruption. Some applications might not work properly after the upgrade and might have to be reinstalled. There is a greater chance of complications.It is crucial to declare a maintenance window or switch to a backup system for the duration of the upgrade. During this period, any websites or applications hosted on the node are inaccessible. It is impossible to avoid some downtime while the updates are installed and the system reboots and initializes.Users do not have to remember to reinstall a critical program or import data from the original node.The Ubuntu upgrade procedure is well tested and generally reliable.Depending on the size of the new release, the node might be fully operational in as little as 15 minutes. This is the easiest and fastest method of upgrading a node.Some of the advantages and disadvantages of this method, and other factors to consider, are as follows: The files and applications on the system are left unchanged and the node can immediately resume operations after the upgrade. Ubuntu downloads and installs the new release of the operating system on the same system. In an inline upgrade, the primary node is upgraded in place using either the GUI or command line directives. However, it is important to understand both methods to make an informed choice. This guide only explains how to perform an inline upgrade. These are the inline upgrade method and the clean install approach. A new version (5.15) of the Linux Kernel.Updates and enhancements are available for Apache, MySQL, Perl, PHP, PostgreSQL, Python, and Ruby. New releases of applications and toolchains.Firefox availability through a Snap package.GNOME 42, which includes a streamlined user interface, on-screen notifications, and better multi-monitor support.A better display, featuring double the frame rate.Enhanced performance and better power efficiency. ![]() In addition to the longer support period, Ubuntu 22.04 includes these other features and improvements: In addition, most application developers test their programs more thoroughly against the latest LTS release. This is superior to the Ubuntu 20.04 schedule, where support ends in April 2025. Ubuntu generally supports their LTS releases for five years, which means Ubuntu 22.04 is supported until April 2027. Ubuntu 22.04 LTS from Canonical is also referred to as “Jammy Jellyfish”. This guide describes how to perform an inline upgrade from Ubuntu 20.xx or 21.xx to 22.04. Upgrading to the new release ensures the system can access the most recent security upgrades and application packages. Although Ubuntu 20.04 LTS ( Long Term Support) is still supported, users should upgrade Ubuntu to the more recent 22.04 LTS.
