MAAS installed via d-i/tasksel: fails when opening the browser to /MAAS

[C de-Avillez]

Fresh install of 20121014, selecting The MAAS option/new MAAS server on the initial menu.

ProblemType: BugDistroRelease: Ubuntu 12.10
Package: debian-installer (not installed)
ProcVersionSignature: Ubuntu 3.5.0-17.28-generic 3.5.5
Uname: Linux 3.5.0-17-generic x86_64

WORKAROUND:

Do *not* install MAAS via the initial installer selection; install a normal server, then, after booting into the system, 'sudo apt-get install maas'.

[C de-Avillez (hggdh2)]

crap. It seems ubuntu-bug gets lost if you copy the apport report to another system, and call if from there. The d-i syslog that apport added in was from the reporting system, not from the failing system...

I tried to open the MAAS URL, and received "The server encountered an internal error..."

Looking at /var/log/apache2/error.log I see the following python backtrace:

Status changed to 'Confirmed' because the bug affects multiple users.

[Robie Basak (racb)]

I think this is a dupe of bug 1065763. Carlos, does Dann's workaround of "'dpkg-reconfigure maas-region-controller' (w/o changing any settings)" work for you?

[Andres Rodriguez (andreserl)]

As Robie mentioned, this is really not an issue of the debian installer. The issue is related to the way how MAAS is installing and creating the necessary RabbitMQ queues. For this reason, I'm marking this as duplicated of the bug above.
