WebUI do not work after fresh install

[moimael]

After installing a fresh ubuntu 14.04 (twice), following every step of this doc :

http://maas.ubuntu.com/docs/install.html#disc-install

I can't access the webui on http://<ip_address>/MAAS

I always get the error :

"Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at webmaster@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log."

Here is the apache error log, the error keep repeating :

[Launchpad Janitor (janitor)]

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

[Jonathan (jfrancis-p)]

I've found that if I perform a fresh install, without internet access (while still having a fully configured network), that the install works and I have full access to the web ui.

[JP (jungjphi)]

Thanks Jonathan for the work around.
I tried the MAAS install option with a network connected machine, I got the error.
I tried a server base install, then adding MAAS components (apt-get) with a network connected machine, I got the error.
But installing from ISO with network card configured and cable unplugged delivered a working solution.

[Zack Parrish (munson3333)]

I can also get what appears to be a functioning MAAS controller with web UI following Jonathan's work around. However, I'm still having a heck of a time getting the web UI to recognize the boot images I've imported through MAAS command line. It's also proving quite difficult to get a node to show up in the web UI nodes page.

For the record, I'm testing all of this on VMs. The controller and all nodes will be virtualized.

Also, if I run:

sudo apt-get update
sudo apt-get upgrade

it breaks my working installation and goes right back to the "Internal Server error" message from Apache. Updating does pull down an update to:

python-django

which appears to be tied to a lot of the originally posted errors.

[Torkel Lyng (torkel-lyng)]

Encountered the same error here, unable to import functools.partial after fresh installation. Current state of 14.04 Server MAAS installation is broken.

[Alessandro Pilotti (alexpilotti)]

As a temporary workaround, I got it working with:

sudo apt-get install -y python-django=1.6.1-2

[TechnicalAbuse (c-ubuutu-f)]

The python-django=1.6.1-2 downgrade worked on my installation.

[Marc Deslauriers (mdeslaur)]

This is likely because of the python-django security update, see #1311433

[Jean-Daniel Bussy (silversurfer972)]

I confirm the workaround. I got it working with:

sudo apt-get install -y --force-yes python-django=1.6.1-2
sudo dpkg-reconfigure maas-region-controller
