Description Kubuntu-User 2024-05-03 11:39:34 UTC 
SUMMARY

If I would like connect on my Kubuntu 24.04 to a open Wifi with OWE like ffm.freifunk.net, then I am unable to connect and I receive a error message in /var/log/syslog:
"802-11-wireless-security.key-mgmt: Access point does not support PSK but setting requires it"

Additional hint - the issue occurs with owe networks (https://en.wikipedia.org/wiki/Opportunistic_Wireless_Encryption)


STEPS TO REPRODUCE
1. Setup a Wifi Device with OWE, for example flash a device with freifunk.net OpenWRT Firmware: https://firmware.ffffm.net/
2. Watch available Wifi networks
3. "Connect" with free owe network

OBSERVED RESULT

The wifi data of ffm.freifunk.net:


bash$ nmcli dev wifi 
IN-USE  BSSID              SSID                     MODE   CHAN  RATE        SIGNAL  BARS  SECURITY  
        DE:83:89:1B:D6:A8  ffm.freifunk.net         Infra  1     130 Mbit/s  90      ▂▄▆█  OWE       
        DE:83:89:1B:D6:AA  owe.ffm.freifunk.net     Infra  1     130 Mbit/s  90      ▂▄▆█  OWE       



EXPECTED RESULT

The open wifi with OWE should get an connection.

The workaround ist curently this:
root@bash# nmcli device wifi connect ffm.freifunk.net
Device 'wlp58s0' successfully activated with 'db.....2'.

Wifi scan data for affected open wifi network with owe

Here a scan of the affected open wifi with OWE ffm.freifunk.net

I can confirm this bug on Fedora 40:

NetworkManager-1.46.2-1.fc40.x86_64
kf6-networkmanager-qt-6.5.0-1.fc40.x86_64
plasma-nm-6.1.4-1.fc40.x86_64

This only happens trying to connect to an unknown network. After manually creating a network profile using nmcli it connects just fine:

nmcli conn add type wifi con-name '<NETWORK NAME>' ssid '<NETWORK NAME>'
Comment 3 Tim Starling 2024-09-29 14:07:41 UTC 
I hit this when I tried to connect to the free wifi at Dallas Airport, using Kubuntu 24.04.

Maybe it will be fixed by this commit from June, when it filters down to us?
