ubuntu_fan_smoke_test failed with unable to fetch file from http://ports.ubuntu.com on PowerPC

(It works on other arches in different MAAS server, so it looks like some network config issue)

After looking @ lp#1840904 This looks like its nameresolv issue in the lab in which the power machine resides. I'll have to deploy one in order to fix this and find out whats causing it.

[Sean Feole (sfeole)]

Marking the linux package invalid as this is clearly a busted test

[Sean Feole (sfeole)]

Here is the problem.

Fanatic test-local-docker, creates a local docker container and imports local DNS via systemd-resolv.conf , it tries to install "Ping" and can't do that because of our firewall, well... the firewall in the lab.

It's blocking access to ports.ubuntu.com..

2 ways we can fix this..

Need to install docker manually, prior to running the teest and preseed docker templates to add

Acquire::http::Proxy "http://<OUR PROXY>:3128"; so that it imports to /etc/apt/apt.conf

OR

we update the firewall rules to allow access to ports.ubuntu.com from all machines in this lab.

Giving we don't own that network it may require some haggling. updating our test may be the least invasive, but it's a pain in the rear.
