Public bug reported: Installed a 18.04 server image, and installed NetworkManager.
NetworkManager comes with a "/usr/lib/NetworkManager/conf.d/10-globally- managed-devices.conf" file where it speciefies that all devices are by default unmanaged except for types "wifi" and "wwan". Now, the problem is that the filter should apply to "gsm" or "cdma" types, not "wwan". E.g.: [keyfile] unmanaged-devices=*,except:type:wifi,except:type:gsm,except:type:cdma Before the change: $ nmcli d DEVICE TYPE STATE CONNECTION wlan0 wifi connected Bumbu eth0 ethernet unmanaged -- cdc-wdm0 gsm unmanaged -- lo loopback unmanaged -- After the change: $ nmcli d DEVICE TYPE STATE CONNECTION wlan0 wifi connected Bumbu cdc-wdm0 gsm connected cell eth0 ethernet unmanaged -- lo loopback unmanaged -- ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1780606 Title: NetworkManager not able to manage WWAN devices in 18.04 server Status in network-manager package in Ubuntu: New Bug description: Installed a 18.04 server image, and installed NetworkManager.
