<br>
Bakc with Ubuntu 16.04, I tried modifying the old networking script <br>
using the ifclass command. If the UBUNTU class was defined, it generated <br>
a /etc/netplan/10-interfaces file. Otherwise, it ran the old code to <br>
generate a /etc/networking/interfaces file.<br>
<br>
I think the reason I couldn't get it to work was because of a bug in <br>
NetworkManager. It looked like NetworkManager would neither make that <br>
interface work nor release it so it could be configured by netplan. This <br>
was a long time ago and my memory is a little fuzzy but I recall typing <br>
in network manager commands to try to get it to stop managing the <br>
interface, it saying it wasn't managing the interface, while at the same <br>
time, a listing of the interfaces it managed showed the interface. Now <br>
that I think about it, I believe I worked on it for way more than 10 <br>
minutes because I recall doing a file-by-file comparison of the configs <br>
from a regular Ubuntu install and an FAI install and finding no <br>
difference. The files in /etc were identical yet it worked in a normal <br>
install of Ubuntu but not in the FAI install.<br>
<br>
I finally just added ifupdown to the packages installed during an Ubuntu <br>
install. So I've been subverting Ubuntu's normal network config process <br>
for years now. I just don't do it the way Ubuntu would normally do it. I <br>
figure when/if Debian switched to netplan, the FAI developers will <br>
modify FAI to account for it.<br>
<br>
Now that you've brought it up though, I might give it another try when I <br>
upgrade all of my workstations to Ubuntu 18.10 during semester break in <br>
January. If I get it to work, I can post a howto here.<br>
