Some more information about the issue:

* The above output shows that devices are not managed by nmcli
After some investigation we found couple of suggestions like
1. 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.

manager/+bug/1638842
For the latest version(18.04), none of the above solutions worked.
