Ran ./paver_local.sh sync to initialize Geonode. Expected to run through initialization process properly.

Actual Behavior

Captured Task Output:

python -W ignore manage.py makemigrations --noinput
Build failed running pavement.sync: Subprocess return code: 1

Steps to Reproduce the Problem

Get Geonode files

1. sudo mkdir -p /opt/geonode/; sudo usermod -a -G www-data $USER; sudo chown -Rf $USER:www-data /opt/geonode/; sudo chmod -Rf 775 /opt/geonode/
2. cd /opt; git clone https://github.com/GeoNode/geonode.git -b 4.2.x geonode

#Install Geonode file dependencies
3. cd geonode
4. pip install -r requirements.txt --upgrade
5. pip install -e . --upgrade
6. pip install pygdal=="gdal-config --version.*"

Initialize Geonode

7. sudo chmod +x *.sh
8. sudo chmod -Rf 777 geonode/static_root/ geonode/uploaded/
9. ./paver_local.sh sync
