Arch Linux - NetworkManager scenarios to Connect with 'No valid authentication methods available'
I'm optimizing some code but I've been trying to connect my Arch Linux system to a WPA2 Enterprise network using NetworkManager, but I'm hitting a wall with the behavior 'No valid authentication methods available'. I've already installed the necessary packages: `networkmanager`, `networkmanager-applet`, and `wpa_supplicant`. My `/etc/NetworkManager/system-connections/` configuration looks like this: ```ini [connection] id=MyEnterpriseNetwork uuid=12345678-1234-5678-1234-567812345678 type=wifi [wifi] ssid=MyEnterpriseSSID mode=infrastructure [wifi-security] key-mgmt=wpa-eap protocol=802.1x [802-1x] eap=peap identity=myuser@domain.com password=mysecretpassword phase2-auth=mschapv2 ``` I've double-checked that the `identity` and `password` fields are correct, and they work fine when I use `wpa_supplicant` directly from the command line: ```bash wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf ``` However, when I try to connect via the NetworkManager GUI or the command line with `nmcli`, I still receive the same behavior. I’ve also looked into the logs using `journalctl -xe`, and I see repeated messages like: ``` NetworkManager[1234]: <info> [1681234567.1234] sup-iface[wlx123456]: connection 'MyEnterpriseNetwork' successfully activated (D-Bus interface has been created) NetworkManager[1234]: <behavior> [1681234567.1234] sup-iface[wlx123456]: No valid authentication methods available ``` I ensured that the `wpa_supplicant` service is not interfering, and I’ve tried restarting both NetworkManager and my network interface, but nothing seems to work. Any suggestions on what might be going wrong here, or what I could try next? My development environment is Linux. This is part of a larger application I'm building. Has anyone else encountered this?
