do-release-upgrade failure (trusty->xenial) when squid3 is installed

David,

I just upgraded from trusty to xenial with MAAS 1.9.1 installed and I did not run into the same errors that you did. I am wondering if it had to do with the options that you chose while upgrading?

1. I had some warning about squid3 and I clicked on 'y' to continue.
2. There was a long message about upgrading from postgresql-9.3 to postgresql-9.5, I clicked 'OK'.
3. There was a message about postgresql-common being modified locally, I clicked on 'Install package maintainer's version'. (I assume this is where you might have chosen differently).

Upgrading proceeded without any errors and I have a fully functional MAAS 2.0 version with xenial.

Could you verify the steps/options you chose while doing the upgrade?

Thanks,

Newell

David,

Actually I see the options you chose in screen.log. Taking a look now.

David,

My questions from comment #2 stand as from screenlog.0 it is hard to discern what options you chose for the popup questions. Thanks.

Others have ran into a similar issues perform "dist-upgrade" looking at the log has to do something with our dependency ordering.

dpkg: dependency problems prevent configuration of maas-region-controller:
 maas-region-controller depends on maas-dns (= 2.0.0~beta3+bzr4941-0ubuntu1); however:
  Package maas-dns is not configured yet.
 maas-region-controller depends on maas-region-api (= 2.0.0~beta3+bzr4941-0ubuntu1); however:
  Package maas-region-api is not installed.

dpkg: error processing package maas-region-controller (--configure):
 dependency problems - leaving unconfigured

The reason the other dependencies didn't install:

dpkg: dependency problems prevent configuration of squid3:
 squid3 depends on squid3-common (= 3.3.8-1ubuntu6.6); however:
  Package squid3-common is not installed.
  Version of squid3-common on system, provided by squid-common:all, is <none>.
 squid (3.5.12-1ubuntu7) breaks squid3 (<< 3.5.12-1ubuntu1~) and is unpacked but not configured.
  Version of squid3 to be configured is 3.3.8-1ubuntu6.6.

(sorry, I thought I commented earlier but I must not have hit post)

The options that Newell posted are the ones I selected.
