add-apt-repository вызывает ошибку Python

Недавно я обновил ubuntu 14.04 до kubuntu 16.04. Когда бы я ни пытался добавить репозитории ppa через «add-apt-repository», это вызывает ошибку Python. Пожалуйста, помогите мне решить эту ошибку или предложить альтернативные методы. Это проблема с Python? Я пытаюсь добавить вино, используя "sudo -E add-apt-repository ppa: ubuntu-wine / ppa". Я получаю следующую ошибку
