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

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'.
