The simple way to Uninstall Software On Ubuntu PC is to use the Ubuntu Software center which is the one-stop shop for installing the number of applications within Ubuntu.
Ubuntu has a launch bar on the left side of the system screen. To start the Ubuntu Software center click on the icon on the launch bar that looks like a shopping bag with the letter A on it.
How To Uninstall Software On Ubuntu Using Ubuntu Software Center
The Ubuntu Software center has three tabs:
Click on the “Installed” tab and scroll down until you find the application you want to uninstall.
To uninstall the software package click on the “Remove” button.
While this works for many packages it doesn’t work for all of them. If you cannot find the program that you wish to uninstall in the list then you should move onto the next step.
Uninstall Software On Ubuntu Using Synaptic
The main problem in Ubuntu Software center is that it doesn’t show all the applications and packages that are installed on your computer.
A very good tool for removing software is called “Synaptic”. This tool will show you each and every single package installed on your system.
If you wish to install “Synaptic” then open the Ubuntu Software Center by clicking on the shopping bag icon with the Ubuntu launcher.
Make sure that the “All” tab is selected then type Synaptic and search for “Synaptic” using the search bar.
Once you get the search reasult for “Synaptic” click on the “Install” button. You will be asked for your password. This ensures that only users with the correct permissions can install software. So enter your password to continue.
To run “Synaptic” press the super key on your keyboard. The super key differs depending on the computer you are using. On systems designed for the Windows operating system, it is denoted on your keyboard with the Windows logo. You can also get the same result by clicking on the icon at the top of the Ubuntu launcher.
The Unity Dash will appear. In the search column type “Synaptic”. Click on the newly installed “Synaptic Package Manager” icon which appears in the search result.
If you know the name of the application that you want to uninstall click on the search button on the toolbar and type the name of the package. To narrow the results you can change the “Look In” drop-down to just filter by name instead of name and description.

If you don’t know the exact name of the package and you just wish to see all the installed applications click on the “Status” button on the bottom left corner of the screen. Click on the “Installed” option in the left panel.
To uninstall a application/package right click on the name of the package and choose either “Mark For Removal” or “Mark For Complete Removal”.
The “Mark For Removal” option will simply remove the package that you have selected to uninstall.
The “Mark For Complete Removal” option will remove the package and any configuration files associated with that package. There is a admonition, though. The configuration files that are removed are only the generic ones installed with the application.
If you have any configuration files listed under your own home folder they will not be deleted. These have to be removed manually by your self.
To complete the removal process of the software click the “Apply” button at the top of the screen.
A warning window will open showing the name of the packages that are marked for removal. If you are sure you want to uninstall the software click on the “Apply” button.
How To Uninstall Software On Ubuntu – Command Line Interface
The Ubuntu terminal will give you the ultimate control for uninstalling software or packages.
In most cases using Ubuntu Software Center and “Synaptic” are adequate for installing and uninstalling software.
However, you can uninstall software on Ubuntu using the terminal and there is one important command I will show you which is not available in the graphical tools.
There are several ways to open a terminal using Ubuntu. But, the easiest is to press CTRL, ALT, and T at the same time.
To get a list of the applications installed on your system, run the following command:
sudo apt --installed list | more
The above commands shows a list of applications installed on your system one page at a time. To see the next page simply press the “space bar” or to quit out press the “q” key.
To remove a application run the under-mentioned command:
sudo apt-get remove
Replace with the name of the package you want to remove.
The above command works much like the “Mark for removal” option in Synaptic.
To go for the complete removal run the under-mentioned command:
sudo apt-get remove --purge
As before replace with the name of the package you want to remove.
When you install an application a list of packages that the application depends on are also installed.
When you remove an application these packages are not automatically removed.
To remove packages that were installed as dependencies, but which no longer have the parent application, installed run the under-mentioned command:
sudo apt-get autoremove
Now you have learned everything you need to know in order to remove packages and applications within Ubuntu.
