Install and configure for Ubuntu in Installation Guide for Key Manager Service

[PRAVIN]

The database section for /etc/barbican/barbican.conf gives error if set this connection for mysql while populating the database using "su -s /bin/sh -c "barbican-manage db upgrade" barbican"
[database]
...
connection = mysql+pymysql://barbican:BARBICAN_DBPASS@controller/barbican

so it needs to be set to
[database]
...
sql_connection = mysql+pymysql://barbican:BARBICAN_DBPASS@controller/barbican
