[Francis J. Lacoste]

After installing maas 0.1+bzr266+dfsg-0+267+20~precise1, I try to access http://localhost/MaaS and I get an Internal Server Error. Relevant part of the error_log:

Doing:

$ sudo touch /var/log/maas/maas.log
$ sudo chown root.www-data /var/log/maas/maas.log
$ sudo chmod 620 /var/log/maas/maas.log

fixes the issue.

Note that the /var/log/maas/oops directory is also owned by root.root and doesn't allow www-data to write to it, which it will need to write OOPSes.
