大家好，我想将我们大学（hs-augsburg）的树莓派连接到 eduroam 网络。我使用的是 Wpa_supplicant 2.8 版。我不能/不知道如何升级到 2.9 版。我将 wpa_supplican.conf 更改为（用户和密码已替换，登录数据在另一台设备上测试正确）：

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE

network={
   ssid="eduroam"
   proto=RSN
   key_mgmt=WPA-EAP
   eap=PEAP
   identity="USER@hs-augsburg.de"
   password="PASSWORD"
   phase1="peaplabel=0"
   phase2="auth=MSCHAPV2"
}

如果我启动 wpa_supplicant，它会尝试连接但失败：

sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

错误：
