安装Debian11因为在安装软件一步失败，导致有部分软件未安装成功，即使系统起来了，但默认没有网络，需要手动启用：dhclient 后才有网络，然而在网上搜索到需要把网卡添加到NetworkManage里，但用命令添加也无效：
ytian@debian:~$ nmcli device status
DEVICE TYPE STATE CONNECTION
wlp3s0 wifi disconnected –
p2p-dev-wlp3s0 wifi-p2p disconnected –
enp7s0f5 ethernet unmanaged –
lo loopback unmanaged –
ytian@debian:~$ sudo nmcli device set enp7s0f5 managed yes
[sudo] password for ytian:
ytian@debian:~$ nmcli device status
DEVICE TYPE STATE CONNECTION
wlp3s0 wifi disconnected –
p2p-dev-wlp3s0 wifi-p2p disconnected –
enp7s0f5 ethernet unmanaged –
lo loopback unmanaged –
用命令添加看起来没有成功，这是什么？
