Ubuntu 20.04网络是通的，所有上网功能都正常，但是网络图标上却是一个问号，就和无法访问互联网时一样。系统是如何判断更新这个图标的？
代码： 全选
nmcli -p n c checkconnectivity [check]
Get network connectivity state. The optional check argument tells
NetworkManager to re-check the connectivity, else the most recent known
connectivity state is displayed without re-checking.
Possible states are:
none
the host is not connected to any network.
portal
the host is behind a captive portal and cannot reach the full Internet.
limited
the host is connected to a network, but it has no access to the
Internet.
full
the host is connected to a network and has full access to the Internet.
unknown
the connectivity status cannot be found out.
