pip не обновляет awscli

Я не нашел никаких ссылок на это в Google, но у меня эта проблема буквально на десятках экземпляров AWS EC2 CentOS. Если awscli еще не существует, он устанавливается нормально. Однако, начиная с v1.4.3, любая попытка обновления до> = 1.4.4 ('pip install --upgrade awscli') приводит к следующим ошибкам:

Те же ошибки возникают на машинах с обновлениями версии aws 1.4.3 -> 1.4.4, 1.4.3 -> 1.5.0 и 1.4.4 -> 1.5.0.
