A user should not be misled into trying to install applications that are not available in the Debian repositories
When an application is no longer available for installation from the Debian repositories that a user's FreedomBox installation is pointing to, the application should not be listed in the apps page as an installation candidate.
When an application becomes unavailable in the Debian repositories
Then the application should not be shown in the apps page
When an application becomes available in the Debian repositories
Then the application should be shown in the apps page
And the application should be installable
