nmcli con up Wired\ connection\ 1
Error: Connection activation failed: No suitable device found for this connection
(device eno1 not available because profile is not compatible with device (permanent MAC address doesn't match)).
该ethernet.mac-address属性似乎有误。
nmcli connection show "$PROFILE"使用或--检查配置文件的内容，nmcli -o connection show "$PROFILE"其中“$PROFILE”是'Wired connection 1'。
然后调整ethernet.mac-address为合适的值。可能的话，只需取消设置并进行设置connection.interface-name即可。
nmcli connection modify "Wired connection 1" ethernet.mac-address '' connection.interface-name eno1。
然后使用 重新激活配置文件nmcli connection up Wired\ connection\ 1。
请参阅man nm-settings连接配置文件的属性的含义。
