сквид: org.freedesktop. PolicyKit1> не был обеспечен никаким .service

Я пытался установить сквид, но когда попытка перезапустить сквид у меня есть следующая ошибка

Не удалось перезапустить squid.service: имя org.freedesktop. PolicyKit1 не был обеспечен никакими .service файлами, Посмотрите системные журналы и 'systemctl состояние squid.service' для деталей.

Когда я работаю systemctl status squid.service результат

что-нибудь я должен сделать? просто попытайтесь получить кэширующиеся настройки прокси, но с ограниченными знаниями...
