No Permissões para o centro de software

Question

Acabei de instalar o Ubuntu 13.04 (vindo de 11.04) hoje. E não posso usar o Centro de Software do Dash. Quando eu começo a partir do painel, ele sempre diz que eu não tenho permissões suficientes para instalar o software. Mas meu usuário está no grupo sudo adm e lpadmin, como deveria ser. A única maneira de usá-lo é com: "sudo software-center" no console. Por que não pede minha senha como sempre? Qual é o problema aqui?

Se, por engano, você tiver algo parecido com /usr/share/polkit-1/actions/org.debian.apt.policy file:

...

  <action id="org.debian.apt.install-or-remove-packages">
    <description gettext-domain="aptdaemon">Install or remove packages</description>
    <message gettext-domain="aptdaemon">To install or remove software, you need to authenticate.</message>
    <defaults>
      <allow_any>no</allow_any>
      <allow_inactive>no</allow_inactive>
      <allow_active>no</allow_active>
    </defaults>
  </action>

...

você receberá o seguinte aviso ao tentar instalar algo do Ubuntu Software Center:

Você pode verificar também os detalhes do aviso.

Portanto, verifique o arquivo /usr/share/polkit-1/actions/org.debian.apt.policy e verifique se está assim:
