dbupdate fails with configobj.MissingInterpolationOption error

[anongoblin]

I am trying to deploy mediagoblin on a Raspberry Pi 3B+ according to the instructions found on ​https://mediagoblin.readthedocs.io/en/stable/siteadmin/deploying.html. I've tried on both Raspbian Buster and Ubuntu MATE 18.04.2, but they both fail in the same place, as shown below.

mediagoblin@pi-mate:/srv/mediagoblin.example.org/mediagoblin$ ./bin/gmg dbupdate

configobj.MissingInterpolationOption: missing option "here" in interpolation.

All of the steps leading up to that have executed successfully. I'm attaching the mediagoblin_local.ini file in case I missed something there, but I think everything is correct in it.

Thanks for taking the time to report this issue. I believe this issue is fixed in the "master" branch of the code. Would you mind testing this please?

In your /srv/mediagoblin.example.org/mediagoblin directory, please run git checkout master and then git pull before trying your dbupdate again. Let us know how you go.

Regards,
Ben
