gmg 0.8 with sqlite db

Hello,

Until recently I had the stable version of mediagoblin running on a server with Debian 9 (for the community network project NuestraRed.org). By decision of another network administrator the operating system was upgraded to debian 10, due to this the installation we had of MediaGoblin stopped working. I have been trying to install from scratch a new installation to migrate the data and even update the version I had installed to Python3.7 but I always have the following error after the compilation and installation of all packages are done well:

(mediagoblin)mediagoblin@nosredserver:/home/nosred/media.nuestrared.org/mediagoblin$ ./bin/gmg Traceback (most recent call last):
