I've recently upgraded (via fresh reinstall) from 17.10 to 18.04 and am trying to connect my LTE modem to my telco.

Laptop: Lenovo T470s Modem: Sierra MBIM [1199:907B] (cdc-wdm0) Location: Australia Telco: Optus APN: internet

When I try to connect, I get this in my syslog.

Is Apparmor blocking the connection or something else?

Any help in directing my in my troubleshooting would be appreciated.

Thanks
