软件中心无权限

我今天刚刚安装了 Ubuntu 13.04（之前是 11.04）。我无法从 Dash 使用软件中心。当我从 Dash 启动它时，它总是说我没有足够的权限来安装软件。但我的用户属于 sudo adm 和 lpadmin 组，这是理所当然的。我唯一可以使用它的方式是在控制台中使用“sudo software-center”。为什么它不像往常一样只要求我输入密码？这里的问题是什么？

如果您错误地在/usr/share/polkit-1/actions/org.debian.apt.policy文件中出现了类似这样的内容：

...

  <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>

...

当您尝试从 Ubuntu 软件中心安装某些内容时，您会收到以下警告：

警告

您还可以从警告中查看详细信息。

因此，检查/usr/share/polkit-1/actions/org.debian.apt.policy文件并确保其看起来像这样：
