Update Runtime For It.mijorus.smile Flatpak App

Nov 24, 2025 by Alex Johnson 48 views

Have you noticed that your Flatpak app, it.mijorus.smile, might be running on an older runtime? Keeping your apps up-to-date is crucial for security, performance, and access to the latest features. This article will guide you through the process of updating the runtime for this specific application, focusing on the ublue-os environment and using Flatpak.

Identifying the Need for a Runtime Update

Before diving into the update process, let's understand why this update is necessary. The flatpak-tracker has identified that it.mijorus.smile currently uses the org.gnome.Platform/x86_64/48 runtime. However, a newer runtime, org.gnome.Platform/x86_64/49, is now available. This discrepancy indicates that an update is needed to ensure the application benefits from the latest improvements and fixes offered by the newer runtime. Ignoring these updates can lead to compatibility issues, reduced performance, and potential security vulnerabilities.

The fact that it.mijorus.smile has 1932 monthly downloads suggests it's a popular application, making the runtime update even more critical. A widely used app running on an outdated runtime can impact a significant number of users. Furthermore, the application's presence in sources like bluefin highlights its integration within specific systems, emphasizing the need for seamless updates within those environments.

Step-by-Step Guide for App Maintainers

If you're an app maintainer, updating the runtime is a straightforward process. By following the steps outlined in this guide, you can ensure your application remains compatible, secure, and performs optimally. The update process primarily involves modifying the application's manifest file and testing the changes thoroughly.

Step 1: Update Your Manifest File

The manifest file acts as the blueprint for your Flatpak application, defining its dependencies, runtime environment, and other crucial details. To initiate the runtime update, you need to modify this file. Typically, the manifest file is named something like it.mijorus.smile.json or it.mijorus.smile.yml.

Locate the Manifest File: Find the manifest file in your application's repository. This file is usually located at the root of your project.
Edit the runtime Field: Open the manifest file in a text editor and locate the runtime field. This field specifies the runtime environment your application relies on. Change the value from org.gnome.Platform/x86_64/48 to org.gnome.Platform/x86_64/49.
Update runtime-version (if applicable): If your manifest file includes a separate runtime-version field, update it to match the new runtime version. This ensures consistency across your application's runtime configuration.

Step 2: Update SDK (if needed)

The Software Development Kit (SDK) provides the tools and libraries necessary to build and run your application. If your app uses an SDK, it's essential to update it to align with the new runtime version. This step guarantees compatibility between your application's build environment and the target runtime.

Identify Your SDK: Determine which SDK your application uses. For GNOME applications, it's typically org.gnome.Sdk. For Freedesktop applications, it's usually org.freedesktop.Sdk.
Match SDK Version to Platform: Update the SDK version to match the new platform version (org.gnome.Platform/x86_64/49). For example, if you're using org.gnome.Sdk, change it to the same version as the Platform.

Step 3: Test and Submit Your Changes

Before submitting your update, thorough testing is crucial. This step helps you identify any potential issues and ensure your application functions correctly with the new runtime. Flatpak provides tools to test your application locally before deploying it to a wider audience.

Test Locally: Use the following commands to build and run your application locally with the updated runtime:
```
flatpak-builder build-dir it.mijorus.smile.json --force-clean
flatpak-builder --run build-dir it.mijorus.smile.json your-app-command
```
- flatpak-builder build-dir it.mijorus.smile.json --force-clean: This command builds your application in a clean environment using the manifest file. The --force-clean flag ensures a fresh build, eliminating potential conflicts from previous builds.
- flatpak-builder --run build-dir it.mijorus.smile.json your-app-command: This command runs your application within the Flatpak environment, allowing you to test its functionality with the new runtime. Replace your-app-command with the actual command to launch your application.
Create a Pull Request: Once you've tested your application locally and confirmed it's working correctly, create a pull request (PR) to your app's repository on the flathub GitHub organization. This PR will submit your changes for review and integration into the main Flathub repository.
Flathub Build System: The Flathub build system will automatically test and build your update. This automated process ensures consistency and quality across all Flatpak applications on Flathub.
