昨天,我在注销并登录/重启后更新了我的系统(更新了一些 PAM 文件),但无法连接到 WIFI 或互联网。我的笔记本电脑上没有以太网端口,因此无法检查。我的系统是双启动 win11/ubuntu 21.1,带有 kde 等离子桌面。
syslog 的输出如下。
NetworkManager[594]: <error> [1641487978.9687] bus-manager: fatal failure to acquire D-Bus service "org.freedesktop.NetworkManager: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Connection ":1.10" is not allowed to own the service "org.freedesktop.NetworkManager" due to security policies in the configuration file

我不知道如何解决这个问题。我尝试重新启动 NetworkManager,但没有帮助。
寻求建议。
更新:
安装软件包后,network-manager_1.32.12-0ubuntu1_amd64.deb
我可以通过 USB 网络共享连接到互联网。任务栏中出现网络图标,但没有显示 WIFI 网络,因此无法连接到 WIFI。
