This article explains three methods of installing Stacer on Ubuntu 20.04. Choose the installation method that is most appropriate for your environment.

Method 1: Installing Stacer via PPA Repository

If you want to install the most recent version of Stacer, you can use the PPA repository.

Personal Package Archives (PPA) are software repositories designed for Ubuntu users and are easier to install than other third-party repositories. PPAs are often used to distribute pre-release software so that it can be tested.

Step #1

First of all open the terminal from system application launcher and type the following command to add the Stacer PPA to your system.

$ sudo add-apt-repository ppa:oguzhaninan/stacer -y

Step #2

Then, execute the following commands to install Stacer package on your Ubuntu system.

$ sudo apt-get update && sudo apt-get install stacer -y

At this step, you have successfully installed Stacer on Ubuntu 20.04 system. Now you can launch the application from your system application menu.

Method 2: Installing Stacer using deb package

We’ll download and install the Stacer .deb package from Stacer’s GitHub Page.

Step #1

Visit at Stacer’s GitHub Page to Download the Stacer .deb package.

Step #2

Now type the following command to install the downloaded package.

$ sudo dpkg -i stacer_1.1.0_amd64.deb

You can also use the apt command to install .deb files.

$ sudo apt install stacer_1.1.0_amd64.deb

If you get a dependency error while installing the .deb packages, you can run the following command to fix it.

$ sudo apt install -f

That’s it, Stacer has been installed on your Ubuntu System, and you can start using it.

Method 3: Installing Stacer via AppImage

Before installation let’s understand what is AppImage.

What is AppImage?

We have .deb packages for Debian/Ubuntu based Linux distributions and .rpm for Fedora/SUSE based Linux distributions.

While these packages provide a convenient way of installing software to their respective distribution users, it is not the most convenient for the application developer.

The developers have to create multiple packages for multiple distributions. This is where AppImage comes into picture. AppImage is a universal software package format.

By packaging the software in AppImage, the developer provides just one file to rule them all. End user can use it in most modern Linux distributions.

Step #1

Click on following button to download the latest stable version of Stacer AppImage executable file for Linux from Stacer’s GitHub Page .

Step #2

The downloaded file name would be something like: Stacer-1.1.0-x64.AppImage

By default, the downloaded AppImage file won’t have the execution permission. You will have to change the permission on the file to make it executable and You don’t need root privilege to do that.

Now type the following command to make the AppImage executable.

$ chmod u+x Stacer-1.1.0-x64.AppImage

Step #3

Once you have made the AppImage file executable, just double click on it to run it Or run the following command to install through terminal.

$ ./Stacer-1.1.0-x64.AppImage

That’s It.

Starting Stacer

Stacer can be launched from the command line by typing stacer or In the Activities search bar type “Stacer” and click on the icon.

How to Uninstall Stacer from Ubuntu 20.04

For some reason, If you want to uninstall Stacer, refer following methods.

Method #1

If you have installed Stacer via PPA then uninstall by running the below commands.

Step #1

It’s most likely that you added the PPA using add-apt-repository command. You can use the same command to remove the PPA as well. Just give it --remove option in the command.

$ sudo add-apt-repository --remove ppa:oguzhaninan/stacer

Step #2

As of now we removed the PPA. What about the applications installed using these PPAs? Will they be removed as a result of removing the PPA? The answer is NO.

So this is when ppa-purge comes in picture. It not only disables the PPA but also uninstalls all the programs installed by the PPA or revert them to original version provided by your distribution.

So type the following command to install the ppa-purge package and uninstall the Stacer package.

$ sudo apt install ppa-purge && sudo ppa-purge ppa:oguzhaninan/stacer

Method #2

If you have installed the appication using .deb then uninstall by running the below command:

$ sudo apt-get remove stacer

Method #3

If you have installed the application via AppImage:

Since the software is never installed, there is no need of uninstalling it. Just delete the associated Stacer file and your software is removed from the system.
