+How to Uninstall Deb Packages in Ubuntu
+======
+Installing applications from a deb file is quite simple. You double click on it and it opens in the Software Center application and you install it from there.
+
+[Installing applications from a deb file][1] is quite simple. You double click on it and it opens in the Software Center application and you install it from there.
+
+But what about uninstalling a .deb package in Ubuntu or Debian? How do you remove the package you installed some time back.
+
+While there are several ifs and buts around it, the simplest and most reliable way of deleting a deb file is by using the apt remove command.
+
+```
+sudo apt remove program_name
+```
+
+As you can see, **you need to know the exact package name here**. This may not always be straightforward. For example, if you install Google Chrome on Ubuntu, the program is known as ‘google-chrome-stable’ in the command line. Did you already know that? I guess not.
+
+In this tutorial, I’ll go into detail about finding the exact package name and then using it to remove the application. I’ll also discuss using a graphical method for deleting .deb packages.
+
+### Removing package installed via deb files from Ubuntu
+
+Before I show you how to remove deb packages from the command line, let’s just quickly look at it in the Software Center application.
+
+#### Method 1: Check if the application can be removed from the software center
+
+Ubuntu has the Software Center GUI application that allows to search for applications, install them and remove them.
+
+The Software Center may not show the application installed when you search for it.
+
+![Searching for installed applications may not show any results in Ubuntu Software Center][2]
+
+However, you may still find it under the “Installed” section if you scroll down. The external applications are usually displayed without their logo.
+
+![Some installed applications can be found in the ‘installed’ tab of the Software Center][3]
+
+If you find it, you can remove the application by clicking the trash icon or remove button.

+
+**Bottom line: Check if the application can be removed from the software center.**
+
+#### Method 2: Delete applications using apt command
+
+I am presuming that you don’t know the exact name of the application command. It is only natural that you may not know that Google Chrome is installed as google-chrome-stable and Edge is installed as microsoft-edge-stable.
+
+The tab completion may help if you have the first few letters. Otherwise, you can [list the installed applications with apt command][5] and use grep to search for the application name:
+
+```
+apt list --installed | grep -i possible_package_name
+```
+
+For example, you can intelligently guess that the Google Chrome package should have chrome in its name. You may search it like this:
+
+```
+apt list --installed | grep -i chrome
+```
+
+You may get more than one result in some cases.
+
+![check if google chrome installed in ubuntu][6]
+
+If you are not sure what the packages do, you can always get their details with:
+
+```
+apt info exact_package_name
+```
+
+Once you have the exact package name, you can delete it using the apt remove command.
+
+```
+sudo apt remove exact_package_name
+```
+
+You can also use apt-get remove or dpkg uninstall commands.
+

+
+#### Method 3: Use Synaptic Package Manager to remove deb applications
+
+Another method is to use the [Synaptic Package Manager][8]. Before GNOME created its graphical package manager in the form of the Software Center, Synaptic was the default GUI package manager in Ubuntu and many other distributions.
+
+It is still the recommended tool on the [Xfce desktop environment][9].
+
+Install it first:
+
+```
+sudo apt install synaptic
+```
+
+Open Synaptic and search for the package name. Look for the installed packages that are marked green. Right-click on them and click on ‘mark for removal’. Hit apply after that.

+
+### Did it help you?
+
+I am more than comfortable using the apt command to remove the packages installed from .deb files. But I can understand that not everyone is comfortable using the command line.
+
+I find the Software Center lacking when it comes to the removal of applications installed from external deb files. It could do a better job here.
+
+I hope you have a better understanding of removing deb packages now. Let me know if you have any questions.
