Ubuntu(version <17.04): Creating an empty file(/etc/NetworkManager/conf.d/10-globally-managed-devices.conf) and restarting NM, solved the issue. 2. Ubuntu(version 17.10): Copying the said file(10-globally-managed-devices.conf) from /usr/lib to /etc/ and modifying the "unmanaged-devices" to none, resolved the issue. * link for reference: https://bugs.launchpad.net/ubuntu/+source /network-manager/+bug/1638842 For the latest version(18.04), none of the above solutions worked.
