** Description changed:
I deployed Xenial in this machine with MAAS. After deployment i had re-
configured interfaces manually (on /etc/network/interfaces), and removed
/etc/network/interfaces.d. At some point, I upgraded the machine from
Xenial to Bionic, and everything was working just fine with /e/n/i.
About 2/3 weeks ago, I dist-upgraded bionic for the latest packages, and
after reboot, networking didn't come up.

To recover the machine, what i did is:
- 1. From the console, bring up the interfaces.
- 2. Brought up eno1 manually & added an IP address manually (ip addr add)
- 3. Configured netplan interfaces
- 4. Run sudo netplan apply with the following config:
+ 1. From the console, brought up the interfaces manually (eno1)
+ 2. added an IP address manually (ip addr add)
+ 3. Configured netplan and applied the config:
