ImportError: No module named appearance [SOLVED]

Error comes when starting the container:

root# docker run -v /gt/sc-data-repos/mayan-dms/data:/var/lib/mayan -e MAYAN_DATABASE_ENGINE=django.db.backends.postgresql -e MAYAN_DATABASE_HOST=mayan-edms-postgres -e MAYAN_DATABASE_NAME=mayan -e MAYAN_DATABASE_USER=mayan -e MAYAN_DATABASE_PORT=5432 -e MAYAN_DATABASE_PASSWORD=mayanuserpass mayanedms/mayanedms:latest

Hint: the error is not there if I do not do the volume mount. Basically omit -v /gt/sc-data-repos/mayan-dms/data:/var/lib/mayan from the above command

mayan: starting entrypoint.sh
mayan: changing uid/guid
usermod: no changes
mayan: os_package_installs()
mayan: pip_installs()
mayan: upgrade()
