As Melvyn statet, I do not believe this is a py2 vs py3 issue. On your stacktrace it seems as the migrations of the quickbbs app are conflicting in some way.
Maybe a migration was created using py2 and another using py3 (as they were created 6 months appart - the name of the migration is a timestamp). Take a look at each migration file to analyse what it is doing. And if possible, you can try to merge manually what the migrations are doing and leave only one of them to be run. Another issue could be VCS related, and some migration file was added/ignored on the filesystem making the migrations fail. To test everything, you can backup you DB somewhere and make the migrations again from scratch.
