While these tools offer convenience, the command line provides a more direct and comprehensive method for identifying all Flatpak components, including runtimes.
-
Understanding Application Identifiers
Each Flatpak application is assigned a unique identifier, which is essential for specifying the application during the uninstallation process. The `flatpak list` command displays these identifiers, which are typically in a reverse domain name format (e.g., `org.gnome.gedit`). Accurate identification of the application identifier is critical for executing the correct uninstall command.
-
Distinguishing Applications from Runtimes
The output of `flatpak list` includes both applications and runtimes. Runtimes are shared libraries and dependencies required by applications. While uninstalling an application may not automatically remove its associated runtime, it is important to distinguish between the two. Unused runtimes can be removed separately to reclaim disk space, further optimizing system resources. This distinction is a key consideration for comprehensive system maintenance.
The ability to accurately identify installed Flatpaks, whether through command-line tools or graphical interfaces, is a foundational element of the application removal process.

Basic Uninstall Command
The fundamental command for removing a Flatpak application is `flatpak uninstall [application ID]`. This command initiates the uninstallation process for the specified application. The application ID, typically in the format `org.example.application`, must be accurately entered for the command to execute correctly. For example, to uninstall the GIMP image editor installed via Flatpak, the command might be `flatpak uninstall org.gimp.GIMP`. Errors in the application ID will prevent successful removal.
-
Listing and Identifying Applications
Prior to executing the uninstall command, it is imperative to identify the correct application ID. The command `flatpak list` displays all installed Flatpak applications along with their corresponding IDs, versions, and sources. This step is crucial to avoid inadvertently removing unintended software. Proper use of `flatpak list` minimizes the risk of system instability or data loss.
-
Removing Unused Runtimes
Flatpak applications often rely on shared runtimes, which are sets of libraries and dependencies. After uninstalling applications, unused runtimes may remain on the system, consuming disk space. The command `flatpak uninstall –unused` removes these orphaned runtimes, optimizing system resource utilization. Regular execution of this command is recommended as part of routine system maintenance.
-
Confirmation and Verification
Upon executing the uninstall command, the system prompts for confirmation before proceeding with the removal. This step is a safeguard against accidental uninstallation. After the uninstallation is complete, it is prudent to verify the removal using `flatpak list` to ensure the application is no longer present. This verification step confirms the success of the operation.
The command line provides a granular level of control over Flatpak application management. Its use ensures accurate and complete uninstallation, contributing to a stable and efficient system. While graphical interfaces may offer a simplified approach, the command line remains the most reliable and versatile method for managing Flatpak installations.

Failure to provide the correct identifier can result in the unintended removal of a different application, or a failed uninstall operation. The application identifier can be found by listing all installed applications using `flatpak list`.
-
Dependency Management Considerations
Flatpak applications often rely on shared dependencies, known as runtimes. When removing a specific application, the system does not automatically uninstall these shared runtimes. If no other installed applications require a particular runtime, it remains on the system, consuming disk space. To remove orphaned runtimes, the command `flatpak uninstall –unused` must be executed separately. This two-step process ensures complete removal of the application and its associated dependencies.
-
Data and Configuration Persistence
Flatpak applications store user data and configuration files in dedicated directories. When an application is uninstalled, these data directories are typically retained, preserving user settings and data. To completely remove all traces of an application, including its data, manual deletion of these directories may be necessary. The location of these directories can vary depending on the application and the system configuration.
-
Verifying Successful Removal
After executing the uninstall command, it is essential to verify that the application has been successfully removed from the system. This can be achieved by running `flatpak list` again and confirming that the target application is no longer listed. Furthermore, checking the file system for any residual files or directories associated with the application can provide additional assurance that the uninstallation was complete.
In summary, removing specific applications via Flatpak requires accurate identification, consideration of dependency management, awareness of data persistence, and verification of successful removal.

The proper deletion of this data is therefore an integral part of ensuring a thorough application removal.
-
Location of Flatpak User Data
Flatpak applications store user data within designated directories, typically located in the user’s home directory under `~/.var/app/`. Within this directory, each application has a subdirectory named after its application ID (e.g., `org.example.application`). This directory contains configuration files, saved states, cached data, and other user-specific information. Identifying the correct application ID is crucial for locating and removing the corresponding data.
-
Manual Data Deletion
The removal of user data requires manual intervention, as the standard `flatpak uninstall` command does not automatically delete these directories. Using a file manager or the command line, one must navigate to the `~/.var/app/` directory and delete the subdirectory associated with the uninstalled application. The command `rm -rf ~/.var/app/org.example.application` (replacing `org.example.application` with the appropriate ID) can be used for command-line deletion. Exercise caution when using `rm -rf`, as it permanently deletes files without prompting for confirmation.
-
Data Retention Considerations
In some instances, users may choose to retain application data even after uninstallation. This might be desirable if the application is expected to be reinstalled in the future, as it avoids the need to reconfigure settings or recreate data files. However, leaving unused data can contribute to disk clutter and potential privacy concerns. A considered approach to data deletion is therefore recommended.
-
Potential for Configuration Conflicts
In rare cases, residual configuration files from uninstalled Flatpak applications can conflict with newly installed applications or system settings.
