The problem seems to be that `CURRENT_TIMESTAMP` isn’t a valid default value for mysql \< 5.6.5, hence the nonce table can’t be created (if you looks into logs, you’ll find „invalid value for `added_on`…).

[https://dev.mysql.com/doc/refman/5.6/en/timestamp-initialization.html](https://dev.mysql.com/doc/refman/5.6/en/timestamp-initialization.html)

The shortest solution is `sudo apt-get install mysql-server-5.6`🙂
