Erro do Python Pycharm ao instalar pacotes do pypi no Ubuntu

Eu não sei o que fazer. Nenhum pacote é capaz de instalar. Estou no Ubuntu se for de alguma relevância. A primeira imagem mostra minhas configurações, intérprete selecionado

Aqui está o que acontece quando tento instalar ("+" acima do pacote) numpy. É o mesmo para qualquer outro pacote.

Quando clico em "Detalhes", recebo esta saída de comando:

Error: Traceback (most recent call last):

Isso é o que está no meu "Gerenciar repositórios"

Eu também tentei instalar diretamente da linha de comando sem sorte.

Se alguém tiver alguma sugestão de como resolver esse problema, agradeço muito.
