Step 1: Update Ubuntu via Terminal
There are multiple ways to update Ubuntu. You can do it from the command line terminal or console, and the desktop graphical user interface (GUI).
Ubuntu comes with a tool called Advanced Packaging Tool (APT) that is powerful, easy to use and handles package management.
It’s the default package management and installation tool for Ubuntu and other distributions.
To update Ubuntu from its terminal, simply press the Ctrl + Alt + Delete keys to open its console window when using a desktop computer.
On the terminal, you can run the commands below to check all package repositories for new versions.
sudo apt update
When you run the command above, it will prompt for your password.
The above command won’t update your system. It checks for newer versions of installed programs. When the command finish executing, it displays number of package(s) that can be updated or upgraded if there are never versions available.
To view list of upgradeable packages, simply run the commands below:
sudo apt list --upgradeable
The command above will list all packages that are upgradeable.
Step 2: Upgrade Packages via Terminal
Now that you know which packages are available to upgrade, if you want to upgrade them simply run the commands below:
sudo apt upgrade
Running the commands above will prompt you for your password before executing. Only administrator and members of the administrators group are allowed to upgrade packages.
Running the commands above will list the packages to be upgraded and prompt you to accept the changes that will be done.
You can type Y for Yes.
When you type Y, all packages that are upgradeable will be upgraded.
To simplify the process, you run both commands at the same time on one line. Below is the simplified version of both commands above.
sudo apt update && sudo apt upgrade
Another command to use that’s not in the picture is the autoremove command. This commands removes obsoletes packages that are not needed from your system to clear up disk space.
sudo apt autoremove
This is how one updates packages on Ubuntu via the command line terminal.
You can run three commands above efficiently on line as shown below:
sudo apt update && sudo apt upgrade && sudo apt autoremove

Option 2: Update | Upgrade Software from GUI
Now that you know to update and upgrade packages from Ubuntu terminal, simply follow the steps below to learn how to upgrade packages from Ubuntu desktop interface.
First, logon to Ubuntu desktop.
When you login, go to the Activities Menu, then search for Software Updater.
This is the GUI equivalent to the apt command line tool above.
When the tool opens, it will check for all available upgradeable packages.
If there are packages that are upgradeable, it will give you an upgrade to upgrade them. Simply click the Install Now button to begin upgrading.
When you click the Install Now button, it will prompt you for your password. As mentioned above, only administrator and members of the administrators group can install packages on Ubuntu.
After typing your password, you computer will begin to upgrade packages.
The GUI tool doesn’t have options to remove obsoletes packages from your systems. So you can use the command line option above to remove those packages that are no longer needed by your machines.
