Thanks Marten for that work. I asked the lava-server maintainer to test
this patch, unfortunately the "migrate" call is still failing for him,
albeit with another error further down the road:
{{{
Operations to perform:
Apply all migrations: admin, auth, contenttypes, dashboard_app,
google_analytics, lava_results_app, lava_scheduler_app,
linaro_django_xmlrpc, sessions, sites

}}}
But `linaro_django_xmlrpc` definitely is in the INSTALLED_APPS setting. So
I'm not sure what the problem is... if you want to have a look at the
lava-server code, it's over here:
The migrate operation is done with this version installed:
https://sources.debian.net/src/lava-server/2016.12-1/
But the application's database was created with this version:
https://sources.debian.net/src/lava-server/2014.09.1-1/
Git repo if you want fine-grained history: https://github.com/Linaro/lava-
