Всем ку, пытаюсь установить сертификат cerbot на свой ubuntu сервер

командой "sudo certbot --nginx -d example.com " но получаю следующею ошибку "Traceback (most recent call last):

AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'" что я делаю не так ?

А ты гуглил ошибку? Там предлагают обновить версию PyOpenSSL. Пробовал?
