Nodes fail deploying with 17.10 due to hang on "waiting for network" at boot

[David Tenty]

When I try to deploy an Artful image to nodes that previously deployed properly with 16.04, deployment fails due to timeout. It seems that the curtin install finishes successfully but the nodes are hanging at 'Waiting for network' on boot.

After looking into the image it seems as though MaaS/Curtin are setting the node up with '/etc/network/interfaces' instead of netplan, which is no longer supported.

Output of 'dpkg -l '*maas*'|cat':

Hi David,

The reason of the failure is because you need a newer curtin version. Artful has changed the way it does network (no longer e/n/i, but netplan) and as such, a newer curtin is needed to work alongside cloud-init to write the networking moving forward.

Also, you can obtain the new version of curtin by enabled -proposed as a repository.

I believe there was a similar bug report from manjo before. which was fixed by upgrading to the stable PPA.

However, we do request and require that MAAS as installed from xenial-updates (and all deps) are working correctly.

What is missing from xenial-updates? Please make this bug report affect those packages with xenial series as affected.

[Andres Rodriguez (andreserl)]

You need a newer version of curtin, which is currently available on xenial-proposed.

[Dimitri John Ledkov (xnox)]

Please install curtin from -proposed, and help verifying curtin SRU which should resolve this problem https://bugs.launchpad.net/ubuntu/+source/curtin/+bug/1721808

Upgrading to curtin from xenial-proposed seems to resolve this issue. Thanks.
