I get the same error when I try to edit about any property of any connection in kde5-nm-connection-editor, and also when I try to create a new connection. But every now and then, it will just work. Just managed to create this shared Wi-Fi config, for example:
[connection] id=Nueva conexión 802-11-wireless uuid=65d23f13-asdf-asdf-asdf-fb98asdf8701 type=wifi autoconnect=false permissions=user:chemtox:; secondaries= [wifi] mac-address=00:00:00:00:00:00 mac-address-blacklist= mac-address-randomization=0 mode=ap seen-bssids= ssid=my_shared_connection [ipv4] dns-search= method=shared [ipv6] addr-gen-mode=stable-privacy dns-search= method=auto Later, after 6-7 tries, I managed to change the auth to WPA. So, looks like a pesky one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1569674 Title: [Kubuntu] Fail to connect to wifi after a recent update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1569674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
