HOW TO COMPLETELY UNINSTALL APPLICATIONS BY COMMAND LINE IN UBUNTU

Uninstalling the software from the command line via Terminal is one of the most
important tasks while dealing with troubleshooting a remotely connected Ubuntu
PC. In today’s Terminal Tuts session, let’s take a deep dive into it.


UNINSTALLING SOFTWARE FROM TERMINAL IN UBUNTU

The following guide is tested on Ubuntu 17.10 but should work on older Ubuntu
versions as well as Linux Mint, and elementary OS.



Step 1) To uninstall a software package, you need to know the exact name of it.
We shall use the tdpkg list command for it. Launch ‘Terminal’ and enter the
following command:

Next
Stay





dpkg --list

You should see a long list of applications. Note down the name of the program
which you want to uninstall. For example, I want to remove VLC Media Player,
which is listed as just ‘vlc’.

dpkg –list command listing all apps in Ubuntu 17.10 Terminal

Step 2) To uninstall a program, we shall use remove command along with apt-get,
which is typically used to install applications. Of course, sudo command to
carry out superuser tasks. There are two important things to consider on what’s
your uninstallation plan.

Keep Personalized Settings:

If you are removing a program only to reinstall later, then you may want to keep
the configuration files, which will remember your settings applied in that app.
In such a case, use the remove command as follows:



General format:

sudo apt-get remove package_name

In my case, to remove vlc:

sudo apt-get remove vlc

Complete Uninstallation:

On the other hand, use –purge command to completely uninstall the app if you
plan not to reinstall the app.

sudo apt-get --purge remove package_name



sudo apt-get --purge remove vlc


SOME HOUSEKEEPING

Now that you have uninstalled the software, you may want to do some extra
cleanup to remove the dependencies of the software you uninstalled now or may be
in the past. Dependencies are the apps and libraries that are used by the
software you no longer have in your PC. Note that it is entirely safe to do so
because no application is using them.

sudo apt-get autoremove

As you see autoremove command is generic cleaning command for any obsolete
packages that are left over in your PC.

    Thanks. A very lucid post :).
    
    I have been struggling with removing Postman (an API tool).
    
    Postman is a native app that has been installed to /opt and I can see its
    folders and files there..
    however when I try to uninstall it using Ubuntu Software center, or Synaptic
    or apt or just list it using dpkg – all of the above do not show any postman
    files.
    Any idea what to do??
