if you run "make" and it fails to install wheel, you might run "make" again, but it skips the step of installing python packages.

So I followed this steps exactly: ​https://raspiblog.noblogs.org/post/2018/02/11/installation-of-gnu-mediagoblin/

pyexiv2 did not work so I removed it from mediagoblin_ini I have configured systemd services as per in the docs production deployment. I have successfully uploaded Images and PDF files but whenever I upload audio and/or video, I get the error:

in audio:

I have reviewed all config and tickets but still no fix. I used python3, python2 appears to not work for me, also I use nginx, debian 9.3.

Tested this on e34916.

In previous versions, I used MediaGoblin's fastcgi support to connect nginx to MediaGoblin. In the current Python3 build, fastcgi causes a failure:

$ docker build -t mediagoblin-python3 -f Dockerfile-python3 . && \
  docker run --entrypoint "./lazyserver.sh" mediagoblin-python3 --server-name=fcgi fcgi_host=127.0.0.1 fcgi_port=26543

+ export CELERY_ALWAYS_EAGER=true
+ ./bin/paster serve paste.ini --server-name=fcgi fcgi_host=127.0.0.1 fcgi_port=26543 --reload
Using paster config: paste.ini
Using ./bin/paster
