Check rights of user, from whom you are executing python manage.py syncdb.

This user must have rights to read and write for file /opt/graphite/webapp/test.db

And also to read, write and execute rights for folder /opt/graphite/webapp/

Try this commands (execute from the user, that starts python manage.py syncdb, probably it is current user)

sudo chown `whoami`:`whoami` /opt/graphite/webapp/test.db  # change owner
sudo chmod o+rw /opt/graphite/webapp/test.db  # add rights

sudo chown `whoami`:`whoami` /opt/graphite/webapp/
sudo chmod o+rwx /opt/graphite/webapp/
