伙计们，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版本2.8。我不知道如何升级到2.9版。我将wpa_supplican.conf更改为（已替换用户和密码，登录数据已在另一台设备上正确测试）：
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，它将尝试连接但失败：
sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
错误：
Successfully initialized wpa_supplicant
