Bug Description

Hi,
I'm having difficulty with my MAAS set up 0.1+bzr415+dfsg-0ubuntu2 on 12.04 B2).
I wanted to flush/purge my settings and start again - but now I've lost the ability to re-install the application - I get a --configure error:

psycopg2.OperationalError: FATAL: password authentication failed for user "maas"
FATAL: password authentication failed for user "maas"

My install was quite basic - just following the steps verbatim from wiki.ubuntu.com/ServerTeam/MAAS

I wanted to modify a node and was unable to delete this (I've raised a bug on this [978706]) but as it was a lab set up I thought I'd try and purge the database:

maas flush

This prompted me to delete the database, then I thought I could recreate this using the syncdb command.

I'm now at the stage where I can't re-install maas.

Cheers,

Kev

I ran into the problem mentioned (on install) and I also ran into the same problem when trying to remove maas packages:
