Ubuntu 22.04 Gnome GUI 不要求输入密码来执行特权操作（例如软件更新程序）-您无权执行此操作

截屏

我刚刚安装了 Ubuntu 22.04 Server。之后我安装了 Slim 和 ubuntu-desktop 来获得 GUI。

当我登录 GUI 并打开软件更新程序时，它告诉我“您无权执行此操作”，并且不要求我输入密码。所以我不能用它来安装更新。不久前我在 Linux Mint 上遇到了类似的问题，我安装了 xdrp，并根据一些指南输入了一些解决方法来使其工作。这导致 PolicyKit 无法正常工作。我也再次使用 xdrp，但这次我没有犯同样的错误。

我在这里只发现了一些针对旧版本的旧主题，但据我所知，它们都没有真正的解决方案。

有什么方法可以查明问题的真正原因并加以解决？

有人在另一个线程中要求提供一些输出，这可能也会有帮助。 身份验证错误：无法安装或删除软件 | 您无权执行此操作

答案1

我遇到了这个问题，并弄清楚了原因。但请记住，这可能是一个非常特殊的情况。我专门为我儿子的帐户关闭了这些身份验证弹出窗口，因为 STEAM 有一个烦人的问题：它要求输入管理员用户密码来修改全局网络设置，这是绝对不可接受的。

90-silence-steam.conf我在目录中创建了一个文件/etc/polkit-1/localauthority.conf.d/，其内容如下：

[Stop steam user from prompting for network permissions]
Identity unix-user:username
Action org.freedesktop.NetworkManager.settings.modify.system
ResultActive no
ResultInactive no
ResultAny no

如果您在目录中的某些配置中执行了类似操作/etc/polkit-1/localauthority.conf.d/，那么这可能是原因。因此，您可以撤消所做的任何操作并找到其他解决方法。目前，我只是用禁用了那里的每一行#。

我希望它至少能够帮助那些与我出于同样原因遇到此问题的人。
