PlayOnLinux is a graphical interface for Wine software compatibility that allows Linux users to install Windows-based applications or programs, such as games, Microsoft Office, and even MacOS applications.

After installing PlayOnLinux via terminal, we cannot uninstall it via default applications, such as App Center or Software.

You have to uninstall it again via terminal and delete some files manually.

Generally, PlayOnLinux is installed using the following command:

```[bash] sudo apt install playonlinux ```

So, you can uninstall it by using the following command:

``` sudo apt purge playonlinux ```

After that, clean up any remaining dependencies that are no longer used with the command:

```[bash] sudo apt-get autoremove sudo apt-get autoclean ```

However, there are still quite large files (around 1 GB or more) still in `/home/{username}/PlayOnLinux's virtual drives`. These files are where PlayOnLinux stores its virtual drives to run Windows programs.

You can safely remove it after completing the PlayOnLinux uninstall process. However, if you want to install PlayOnLinux again in the future, I recommend to not removing it.
