As of 2017--2-27, the juju ssh 0/lxd/1 ip route show fails quickly in juju 2.1 on maas 2.0 only starting with

This is the recent static route support change.

The previous Bug #1652130 shown in the issue was fixed.

This is the actual bug:
2017-02-27 17:55:46 WARNING juju.provisioner lxd-broker.go:82 failed to
prepare container "0/lxd/0" network config: unable to look up
static-routes: unexpected: ServerError: 404 NOT FOUND (Unknown API
endpoint: /MAAS/api/2.0/static-routes/.)

I had previously consulted the MAAS API docs:
https://docs.ubuntu.com/maas/2.0/en/api#static-route

Which looked like MAAS 2.0 indeed had the API exposed.

I had previously had code that would have handled missing static-routes
more gracefully, but in review it came up that it didn't seem right to
suppress the error, and the info *I* had on hand looked like MAAS 2.0 was
supposed to support it.

Notices that accessing static-routes is returning a 404 and treats that as just having no static-routes available.

code never landed in 'develop'

[Anastasia (anastasia-macmood)]

Marked as Fix Committed a code landed in 2.1 and we are awaiting confirmation from QA that the branch is better now :D

[John A Meinel (jameinel)]

We still saw this failure in CI, I'm getting credentials to check it directly before I land the next attempt at a fix.

(the error looks the same
2017-02-28 10:28:17 WARNING juju.provisioner lxd-broker.go:82 failed to prepare container "0/lxd/0" network config: unable to look up static-routes: unexpected: ServerError: 404 NOT FOUND (Unknown API endpoint: /MAAS/api/2.0/static-routes/.)
)

PASSED, which looks to be fixed.
