我正在使用 Arch Linux 设置，但在使用网络管理器连接到学校的 WiFi 时遇到问题。我正在使用 nmcli 连接编辑器来设置我的系统连接。
这是我的网络文件的样子：
[connection]
id=MYID
uuid=MY_UUID
type=wifi
interface-name=wlp3s0
[wifi]
mode=infrastructure
ssid=MY_SSID
[wifi-security]
key-mgmt=wpa-eap
[802-1x]
ca-cert=/etc/ca-certificates/trust-source/anchors/ca.crt
eap=peap;
identity=USERNAME
password=PASSWORD
phase2-auth=mschapv2
[ipv4]
dns-search
method=auto
[ipv6]
addr-gen-mode=stable-privacy
dns-seach=
method=auto
当我尝试激活连接时，它被卡住了
Passwords or encryption keys are required to access the wireless network 'SSID'.
connecting (need authentication)
返回之前：“错误：连接激活失败。”
这是 journalctl -ex 的输出（通常它说未能提供所需的机密）。
