Acho que a solução é simples - desabilitar repositórios inexistentes (opt-qt57-xenialeopt-qt57-confiável):
sudo add-apt-repository -r ppa:beineri/opt-qt57-xenial
sudo add-apt-repository -r ppa:beineri/opt-qt57-trusty
sudo apt-get update
Em seguida, adicione os existentesQt 5.7.1 PPAse você precisar desta versão:
sudo add-apt-repository ppa:beineri/opt-qt571-trusty
sudo apt-get update
sudo apt-get dist-upgrade
