Ubuntu is a popular Linux distribution that has been in use for many years. It is a Debian-based distribution that comes with a lot of features and options. If you are looking to update your Ubuntu system, there are a few things you should keep in mind. First, make sure that your computer is up to date with the latest security patches. This includes updates for the kernel, libraries, and applications. Second, make sure that your computer is running the latest version of Ubuntu. This includes both the main release and any updates that have been released since it was last updated. Third, be sure to back up your files and folders before updating your system. This will help you if something goes wrong and you need to revert back to an earlier version of Ubuntu. Finally, be sure to follow the instructions provided by Ubuntu for updating your system. These can include using apt-get or aptitude to install new software or upgrading existing software.
What You Need to Know About Updating
Ubuntu and most of its derivatives offer two methods for updating: a command-line interface tool (called APT) for those who don’t mind using the terminal, and an app called Software Updater for those who prefer a comfortable desktop experience. Software Updater in fact uses APT in the background, managing it for you so you don’t have to remember any commands.
Some Ubuntu-based distros have an app that’s different but similar to Software Updater, like Linux Mint‘s Update Manager. Others allow you to update through an application browser, like Elementary OS‘s AppStore. The instructions below will work much the same for them.
Keep in mind, however, that these updating methods only upgrade packages that you installed through Ubuntu’s enabled repositories. That means that if you downloaded and installed an app from a website, it won’t get updated. The app may have its own built-in updating procedure, or you may need to again download and install the latest version. Check with the app’s vendor to find out.
How to Update Ubuntu in the Desktop
You can begin updating Ubuntu in the desktop by opening Software Updater. Click the “Show Applications” button (nine boxes forming a square), or hit the Super key.
With the application menu open, start typing “Software Updater.” You should see it appear in the list of applications. Click it to launch.
Software Updater will first search for available updates, then show you a list of them with checkboxes you can uncheck should you not want them. If you want to update everything, leave everything checked.
Click “Install Now” once you’re satisfied with the selection.
You’ll be prompted for your password for authentication purposes. Type it in and press Enter.
Once you’ve been authenticated, the installation will begin.
This can take some time, and you may be prompted to reboot your machine once it’s complete. After that, you’re free to use your nice and shiny up-to-date PC!
How to Update Ubuntu in the Terminal
Just like its ancestor, Debian, Ubuntu uses the command line tool APT for managing packages. Ubuntu’s derivatives use it too, like Xubuntu, Raspberry Pi OS, and Linux Mint. These instructions will work for them exactly the same.
Open a terminal and enter the following command to check for updates.
You’ll be asked to confirm your password. Type it in and press Enter.
After APT checks all your repositories, it’ll tell you how many package upgrades are available. If there’s at least one, you can proceed to the next step.
Pass the following command to start upgrading your packages.
You’ll get a readout of all available package updates followed by a prompt to confirm that you want to apply the updates. Type y and press Enter to confirm or use n to cancel.
If you want to only upgrade a specific package, use the command below instead of the upgrade command, replacing package_name with the name of your package.
Want to script like the pros? You can automate the whole process of a full system upgrade in just one command string.
Placing && between commands indicates you want the second command issued immediately after the first is complete, and the -y flag means you want to answer yes to the confirmation prompt when it arrives.
