Quando tento executar o apt update, tenho um problema desse tipo:

Eu tentei descobrir o que está errado, mas não encontrei uma resposta. P.S. Eu não uso um proxy.
Para desabilitar o suporte a IPv6 no Ubuntu, edite o seguinte arquivo: /etc/sysctl.conf .
net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
A adição dessas linhas desativará o suporte a IPv6 (em loopback), um padrão para todas as etginterfaces disponíveis. Você precisará reinicializar as interfaces de rede:
/etc/init.d/networking restart
