Migration failed for SQLite database

[nlrooat]

Following installation instructions I'm trying to run the database migration. The migration is trying to add a foreign key, resulting in the following errror:

Exception 'yii\base\NotSupportedException' with message 'yii\db\sqlite\QueryBuilder::addForeignKey is not supported by SQLite.'

Instead of using (as suggested by the official Yii documentation):
$this->addForeignKey(..)

consider using $options parameter for createTable() function, see http://www.yiiframework.com/doc-2.0/yii-db-migration.html#createTable()-detail.

By the way, I noticed in the down() function of the filemanager_init migration, you drop two foreign keys, but only one was created in the up() function?
