Package: network-manager Version: 1.2.2-1 Severity: important
After I complete a new mobile broadband connection, the dialog for input mobile broadband password is showed (see the attachment file).The "Connect" button can not be pressed unless anything is filled in the dialog. But my provider is not need any username and password. If I edit the configuration file in /etc/NetworkManager/system-connections, delete the username and password. Then connect, the connection can not be established, and I get an error message in daemon.log. The error message is like blew. (NetworkManager:902): NetworkManager-wwan-CRITICAL **: modem_prepare_result: assertion 'state == NM_DEVICE_STATE_PREPARE' failed My laptop is Thinkpad X1 carbon 4th Gen with Debian testing, the mobile broadband slot is embed.
