It is often easier and faster to install a fresh system than to do-release-upgrade, particularly if there are several steps, or if the new version is very different from the previous one. Update & full-upgrade the current system, so that it is up to date. Remove all PPAs and non-standard program packages (that do not belong to the Ubuntu repositories), because they can break the release-upgrade process, There is one exception: You can also do-release-upgrade from the previous LTS version to the next LTS version, for example This method works from a previous version to the next version. You find more details in the built-in manual man do-release-upgrade Backup everything that you don't want to lose before you start on this venture.

Sudo apt install program-package-name # new syntax Sudo apt-get install program-package-name # old syntax It is a good idea to update before installing. When you intend to install a new program package, you can run the following command lines. When you intend to upgrade the system (within the same version of Ubuntu), you can run one of the following command lines sudo apt update & sudo apt upgrade Install a program package, a new package that was not yet installed sudo apt-get upgrade # old syntax Or if you want to upgrade and also perform checks and fixes to upgrade to a fully upgraded and compatible system (this is what I do), sudo apt-get dist-upgrade # old syntax Upgrade all current program packages in the Ubuntu operating system, that are installed automatically or from the repositories or from a PPA.

I can run the updates from 1 location and patch the local machine, 5 machines in a different rooms and the others thousands of miles away over the internet. * Ansible (a professional devOps tool that also works over ssh connections * a script that loops over all the different systems and runs each command (update/upgrade) over ssh * clusterSSH (opens remote terminals on different systems, I type into 1 and all the others get the same command(s) entered) By using a shell/CLI, I have multiple solutions Most don't have any GUI and I don't want to walk around, login, find some program in a menu, click 5 things, and wait on the few that do.
