Comienza reproduciendo el problema en la sesión SSH de Ubuntu 22.04 indicada y, después, ejecuta q doctor y q restart según lo solicitado. Se considera completado cuando vuelvan a funcionar tanto el autocompletado del terminal como las sugerencias en línea, pero el issue no proporciona ningún archivo, prueba ni pasos de reproducción que orienten la implementación.
