My version ubuntu server 18.04. Below worked for me:
1. Creating an empty file(/etc/NetworkManager/conf.d/10-globally-
managed-devices.conf)
2. removing the file(10-globally-managed-devices.conf) from /usr/lib
and finally
3. changing Network renderer to NetworkManager in Yaml file.
Yaml file location: /etc/netplan
My yaml was like this:
network:
ethernets:
eno1:
dhcp4: true
version: 2
Changed to:
network:
version: 2
renderer: NetworkManager
ethernets:
eno1:
dhcp4: true
and I change it to:

* 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.

For the latest version(18.04), none of the above solutions worked.
