Não é possível conectar redes sem fio que exigem senha

Question

Eu posso me conectar a redes Wi-Fi que não exigem senha. Mas quando tento me conectar a uma rede que exige senha, a senha não é solicitada, o Network Manager apenas tenta se conectar e é claro que falha.

Este é o log de / var / log / syslog:

Não sei se isso é importante, acho que esse problema começou após a instalação da anbox . Depois disso, nos resultados ifconfig, wlp2s0 foi substituído por outra entrada (anboxlo se bem me lembro). Agora eu removi anbox e tentei colocar de volta as configurações antigas, procurei os erros na saída ... mas não tive sucesso.

Por favor me ajude aqui. Estarei disponível para fornecer mais informações, conforme necessário.

(O Network Manager parece não estar em execução após a inicialização do sistema. Eu executo estes comandos: $ sudo service network-manager restart às 15:11:25, $ sudo service network-manager stop às 15:13:07 e $ sudo service network-manager start às 15:13:24)

Além disso, deixe-me acrescentar que agora, quando tento conectar-me a um wifi com senha, recebo esta mensagem de erro em pop-up:

  

Falha na conexão

     

A ativação da conexão falhou

     

(2) Conexão ativa removida antes de ser inicializada

    

Answer 1

o daemon de chaveiro provavelmente não está em execução. você pode verificar se está habilitado em aplicativos de inicialização automática, procure por "chaveiro do GNOME"

também, acho que consolekit deve estar sendo executado como um serviço
