[asterisk-users] Asterisk 13.8.0 alembic database update fails.

[Harley Peters]

I get the following error when trying to update date the database via 
contrib/ast-db-manage/alembic -c config.ini upgrade head.
Every previous update has always worked any idea what is wrong.

OS=Debian Jessie, fully up to date.
