Bug Description

Juju 2.7.5

snap info juju:

snap-id: e2CPHpB1fUxcKtCyJTsm5t3hN9axJ0yj
tracking: 2.7/candidate
  2.7/candidate: 2.7.5+2.7-8a81b98 2020-03-19 (10983) 82MB classic

The Trusty cloud images do not have distro-info installed by default leading juju commands to spew the following Warning to stderr.

root@juju-7db4d7-zaza-6013949e4099-3:/var/lib/juju/agents/unit-keystone-0/charm# network-get --primary-address public
2020-03-20 20:39:54 WARNING juju.juju.series supportedseries.go:692 failed to update distro info: open /usr/share/distro-info/ubuntu.csv: no such file or directory
172.20.0.15

The problem with this is there are a number of charm-helpers which mistakenly send stderr to stdout. This effectively breaks important helpers like charmhelpers.core.network_get and others.

The problem does not exist on juju 2.7.4

Thanks, this might be due to some of the series changes made in 2.7.5. Simon can you look into this for 2.7.5 in your morning please?

Is it possible to get this released to the candidate channel, please? It's currently holding up our CI tests as we can't complete gate on the charms as we have trusty-* targets. Thanks.

This is in the 2.7 candidate channel currently. Are you still seeing the issue with that snap?

Alex Kavanagh (ajkavanagh) wrote :

Hi Rick, sorry I didn't spot that as I was looking at just the "candidate" channel. I will test with 2.7/candidate and report back. Thanks!

Can confirm, that in my bastion, 2.7/candidate has solved the issue on trusty. Thanks.
