Ubuntu安装VMware 到最后一步点击Finish按钮时报错

错误一：

vmware-setup-helper requires root access

Having just installed vmplayer on openSUSE Leap 15.1 and find it can only run as root:

I/O warning : failed to load external entity "/etc/vmware/hostd/proxy.xml"

==== AUTHENTICATING FOR org.freedesktop.policykit.exec ====

Authentication is needed to run `/usr/lib/vmware/bin/vmware-setup-helper' as the super user

Authenticating as: root

Password:

polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie

==== AUTHENTICATION FAILED ====

Error executing command as another user: Not authorized

原因：可能是在一个用户下安装的VMware，然后在另一个用户下启动VMware，然后导致报错；

或者    不能在root账户下启动VMware，我的就是这种情况，切换到别的用户就可以了。

请看下面这句话！！！

Run it the first time as Root, to finish the setup.  Then it shouldn't need root afterwards.

第一次以Root身份运行它，以完成安装设置。然后它就不需要Root了。

错误二：

$ synaptic-pkexec
==== AUTHENTICATING FOR com.ubuntu.pkexec.synaptic ===
Authentication is required to run the Synaptic Package Manager

==== AUTHENTICATION FAILED ===

This incident has been reported.

解决方法：

执行如下命令即可

/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1 &

 具体原因我也不清楚，反正问题解决了！_(:з」∠)_
