How to delete program in linux

Linux uninstall package / software using the CLI

Linux uninstall package / software

1. First, you need to find a list of all installed packages on Linux.
2. To uninstall an application, you need to use Linux distro-specific command. For example, use the apt command on Debian or Ubuntu Linux. RHEL/CentOS/Fedora Linux users need to run either the dnf or yum command and so on.
3. Finally, we can use various commands for verification of the uninstallation of a program on Linux.

Let us see all commands in action to uninstall a program on Linux.

Ubuntu/Debian Linux uninstall software

The syntax is as follows to list all installed packages on Debian or Ubuntu Linux using the apt command:
apt list —installed

How to find out exact package names in Debian/Ubuntu/Mint Linux

Use the ‘ dpkg —list ‘ command to get a list of all installed packages on an Ubuntu or Debian/Mint Linux

grep command in action to filter out package names quickly that you want to uninstall

RHEL/CentOS/Oracle Linux

We need to use the yum command for CentOS/RHEL v6.x/7.x. First get a list, run:
sudo yum list installed
sudo yum list installed | grep package
sudo yum list installed | grep zip

yum command in action

Fedora Linux

Again, we need to the dnf command as follows:
## List all installed packages ##
sudo dnf list installed
## Filter out the package named httpd ##
sudo dnf list installed | grep httpd
## Delete the httpd ##
sudo dnf remove httpd

Arch Linux

We use the pacman command on Arch Linux to uninstall software. Pass the Q to list all installed packages on Arch Linux:
sudo pacman Q

4 Ways to Uninstall Software in Linux Mint

At some point, you will have to remove programs from your Linux Mint. In this post, you will learn 4 different ways to uninstall software in Linux Mint.

INTRODUCTION

Usually, in Linux, there are always several ways to do one thing. For example, to install/uninstall an application, some prefer the use of the terminal, while others stick to a software manager.

It also happens there several ways to uninstall software in Linux Mint. I will show you 4 ways to do that and you will be able to pick your favorite.

1. The simplest way is to right-click on an application in the main menu.
2. You can uninstall an application using the software manager.
3. If you use Synaptic, you can also do it from there.
4. Finally, you can always go conservative and use the Linux Mint terminal.

The first two options are clearly focused on the novice user, while the last two are for more advanced users. So, let us start.

VIDEO TUTORIAL

1. Using the right-click in the menu

This is the easiest way to uninstall software in Linux Mint. This method is intended for novices and it is the simplest way. I must confess that I have been using Linux Mint for years and I did not know about this feature.

So, you have to open the Linux Mint menu and look for a program you want to uninstall. I will be uninstalling GIMP image editor as an example. You right-click on the program and you will see the option to uninstall it.

After that, you have to type your user password. Then, you need to confirm that you want to uninstall the software. After this, the program will be removed from your system.

As you can see, you can uninstall software in Linux Mint can be really quick.

By the way, if you liked this Linux Mint icons, you can read how to install them in these Linux Mint icons and themes post.

2. Using the Software Manager

The second way to uninstall software in Linux Mint is through the Software Manager. So, you open Linux Mint Software Manager.

Then, search for the program you want to uninstall. Again, I will use GIMP here.

Finally, click on the Remove button and it will start the uninstall process.

As you can see, this way requires more steps than the previous one, but it may be useful if you are testing different programs and you need to remove a program without leaving the Software Manager.

3. Using Synaptic package manager

Similarly to the previous way, you can uninstall programs on Linux Mint is by using the Synaptic package manager. Synaptic is also a software manager but it is a bit more advanced than the Linux Mint Software Manager.

So, open Synaptic from the main menu.

Next, in the search field, type the name of the program you want to remove. Again, in this case, I will remove GIMP. Select the package and right-click on it.

Here, you have two options to uninstall it:

1. Mark for Removal
2. Mark for Complete Removal

Mark for Removal will just remove a program. Basically, it will do the same what has been done through the Linux Mint menu and through the Software Manager. The second option, Mark for Complete Removal, in addition to removing the program, will also remove all the configuration files in your /etc directory. So, this way you can keep your system clean.

Note that this uninstall does not remove the configuration files from your home directory. If you want to completely get rid of all files associated with a program, you need to remove its config files from your home directory manually. To find these files, unable “Show hidden files” in the view menu of your file manager and search for folders with the program name you want to remove. Usually, they are located right in your home or in

So, for complete removal, choose the Complete removal option and click on the Apply button.

Synaptic will show you a summary of what is going to be done. In my example, you can see many programs will be unchanged and only GIMP will be removed. After you click apply, GIMP will be uninstalled.

4. Using the terminal

Similarly to Synaptic way shown above, you have two options to remove software in Linux Mint using the terminal. Moreover, as you will see below, you can also remove orphan packages using the terminal.

Standard way

So, the most common and standard way is with this command:

And this will be equivalent to the simple remove option in Synaptic. That is it will remove the package but not its configuration files in /etc .

Completely remove (advanced)

However, if you want to completely remove the program you can use the command purge instead of remove .

And this will be equivalent to the Complete Removal in Synaptic — it will remove the package and the configuration files located in /etc .

Both the purge and remove commands will show you a summary of what is going to be removed. Read it carefully and confirm if you agree to remove listed packages. Be careful here because sometime purge may remove important programs as dependencies.

Remove orphan packages

Finally, using the terminal, you can also remove orphan packages using the following command.

And if you want to remove the GIMP configuration files from your home directory, you can also remove them from the command line.

Now all GIMP files are removed.

As you can see the command line way is even more advanced because you are given more flexibility and more options here. For example, we did not see any autoremove option before when we tried to remove through the Linux Mint menu, through the Software Manager, and in the Synaptic package manager.

Conclusion

In Linux, there are always different ways to do the same thing and it is nice because each of these options fits certain users. The different ways to uninstall software in Linux Mint proves it. Some are ideal for newbies whereas others are better for more powerful users.

How to Uninstall Programs from your Ubuntu System

This article describes removing software from your Ubuntu system that you do not need anymore. We are describing software removal both through the graphical user interface (Ubuntu Software Manager) and the command line-the (Terminal).

Please note that you need administrative privileges in order to install/uninstall software from Ubuntu.

We have run the commands and procedures mentioned in this article on Ubuntu 20.04 LTS.

Uninstall Applications Through Ubuntu Software Manager

One way to uninstall software from your computer is through the Ubuntu Software Manager. Click on the Ubuntu Software icon in the Activities toolbar; this will open the Ubuntu Software manager through which you can search for, install and uninstall software from your computer.

Then click the Installed tab from the following view to list all the applications installed on your Ubuntu system:

From the list of applications, look up for the one you want to uninstall and then click the Remove button against it.

In this example, I am removing a software called XCFA from my system by clicking the Remove button against it. When you try to remove an application, the following type of confirmation message appears:

Click the Remove button when you are sure that you want to remove the selected application. When you do so, the following authentication dialog will appear as only an authorized user can remove an application from Ubuntu:

Enter the password for Administrator or a sudo user and then click the Authenticate button.

The selected software will now be removed from your system.

Uninstall Applications Through the Command Line

You can remove installed software from your system through apt-get remove and apt-get purge commands as sudo. But first, you need to know the exact package name through which you installed the software.

The following command will list all the packages installed on your system:

You may want to copy the exact package name; select it, right click and then copy it from the dpkg list for further use.

Use apt-get remove command

The apt-get remove command removes a software from your system but keeps the configuration files and any plugins and settings that you might have installed later. This helps in keeping the same settings when you want to reinstall the software.

Run the following command as sudo in order to remove a software;

You will be asked the password for sudo and given the information about what will be removed from your system.

In this example, I will be removing the OpenJDK package named “openjdk-11-jdk” from my system.

The system will also prompt with a y/n option in order to re-confirm the uninstall procedure. When you click Y, the process will begin and the software will be removed from your system.

Use apt-get purge command

If you want to remove an application completely from your system, also removing any personalized settings, it is best to use the apt-get purge command.

In this example, I will be removing the OpenJDK package named “openjdk-11-jdk:amd64” from my system.

Run the following command as sudo in order to remove a software;

You will be asked the password for sudo and given the information about what will be removed from your system.

The system will also prompt with a y/n option in order to re-confirm the uninstall procedure. When you click Y, the process will begin and the software will be removed from your system.

Bonus: Cleanup the Mess with autoremove

In case you want to remove any dependencies such as the applications and libraries used by the software you once installed that is no longer in use, you can do some housekeeping through the following command:

This will list all the obsolete and unused packaged and left over dependencies taking up important space on your system.

The system will also prompt with a y/n option in order to re-confirm the uninstall procedure. When you click Y, the process will begin and the unwanted software dependencies will be removed from your system.

You have learned two ways to uninstall software from your Ubuntu system; through the Ubuntu Software manager and through the command line. Through the command line, you can opt either to remove the software and keep all the configuration files (apt get remove) or completely remove the software (apt-get purge).
