При попытке запустить

 pip install -r requirements.txt
 

Я получаю вывод:

Я запускаю: Ubuntu 20.04

Версии: Python 3.8.5, pip 20.0.2

Не за прокси. Использование virtualenv, но установка pip также не работает вне virtualenv.

Я пару раз пытался переустановить pip, и у меня есть псевдоним в pip3, поэтому pip должен работать. Я также пытался обновить pip, но всегда получаю, что я уже обновлен в выходных данных.
