Flatpaks need to be installed multiple times before they actually install in UM

Comienza reproduciendo el problema en Update Manager en Linux Mint 6.0.9 con las actualizaciones de Flatpak seleccionadas; después, utiliza la secuencia proporcionada de registros de actualización e instalación para rastrear qué ocurre después de la instalación. Se considera terminado cuando una actualización de Flatpak instalada desaparece después de una instalación o cuando una instalación fallida se informa claramente al usuario.

Describe the bug
There's this frustrating issue in the Update Manager where it may list Flatpak updates, one installs them, it does its thing, but after refreshing, several Flatpak updates show up in the list once again as if they were never installed. There are no errors and no indications that the install failed, but the items continue to list in the Update Manager. After several retries, they may eventually disappear, but this shouldn't happen without an error or communication to the user that something went wrong.
