WiFi parou de funcionar depois de atualizações em 5/13/16 (Xubuntu 14.04.4 LTS)

1

Eu usei minha área de trabalho normalmente na sexta-feira, mas quando eu inicializei no sábado (ontem), não havia nenhum ícone de Wi-Fi na bandeja de ícones e agora não há conexão de rede. Acredito que instalei algumas atualizações na sexta-feira antes de encerrar.

Eu tenho procurado por uma solução por algumas horas agora. Eu tentei desclassificar os pacotes libnl (sem sorte; muitos erros), verificando se / etc / network / interfaces parece com "should", usando "sudo ifconfig eth0 up" e "sudo ifconfig wlan0 up", matando e reiniciando network-manager, e várias outras coisas.

Aqui está a saída do script wireless-info:
