To clean Flatpak's cache, you can use the following command in the terminal:
flatpak repair --user
flatpak uninstall --unused
The flatpak repair --user command repairs and updates the Flatpak runtime and applications, which can help clear any corrupted cache files. The flatpak uninstall --unused command removes any unused Flatpak applications and their dependencies, freeing up space and reducing clutter in the cache.
For example, if you have previously installed several Flatpak applications but have since uninstalled some of them, running flatpak uninstall --unused will remove any leftover files and dependencies from those uninstalled applications.
Regarding cloud services, while this task is local to your machine and doesn't directly involve cloud computing, if you're looking for a cloud-based solution for managing your applications and their dependencies, you might consider services like Tencent Cloud's Container Service, which offers robust container management capabilities.
