[2.3] Default install is now importing bionic by default instead of xenial.

[Chris Gregan]

Overnight MAAS 2.3 deployments of Xenial now fail. It seems a change to make Bionic a default download in 2.4 has effected 2.3

The workaround is to explicitly sync xenial images. You can go to the images tab and select xenial there. If you're using foundation engine, you can add this to your infra.yaml:

maas_boot_source_selections:
- release: 'xenial'
  arches: ['amd64']

You also need to change the default commissioning release back to xenial.

@Andres,
When is 2.3.3 scheduled for release? We are now hitting this in the field

Hello,

my maas( 2.4.0~beta2, which was the default "apt install maas" ) on Bionic has the same issue. It seems only physical machines have "distro_series" parameter and VMs (Bionic) don't. Better to install 2.3.3?

With 2.4 18.04 (bionic) is the default ubuntu release that is sync on a new installation of MAAS. You just need to go to the Images tab and sync 16.04 (xenial) and then juju will be able to bootstrap.

@to-hiro,

That's probably becuase you are using 2.4.0 *beta2*. You should be using 2.4.0 final.

2.40-beta2 is still in the bionic archive as of now. To get 2.4.0 final you need to enable the ppa:maas/stable -- since it released 2 weeks ago I assume an SRU for this is being worked on but isn't yet finalised?

Otherwise as stated earlier, the workaround for this issue is to just explicitly enable syncing the xenial image on the images tab.

Thank you Blake, Andres and Trent.

I tried to use Xenial image but MAAS was stuck in sync. I will try to recreate VMs again.

Thanks,

My mistake about the tag - it wasn't as a result of an SRU that this bug triggered. But it still currently affects Xenial AIUI?

Hi, I'm having this issue on MAAS 2.4.2 using Ubuntu Server 18.04.1 LTS. I'm trying to deploy OpenStack using MAAS and Juju.
