db push not working

[jarc100]

I run the taks grunt push_db --target=staging
this is the result:

Pushing database from 'Local' to 'staging'
>> Creating DUMP of local database
>> Database DUMP succesfully exported to:
>> backups/local/20141210/02-58-28/db_backup.sql
>> Adapt the database: set the correct urls for the destination in the database.
>> Creating DUMP of remote database
>> Database DUMP succesfully exported to:
>> backups/staging/20141210/02-58-28/db_backup.sql
>> Importing DUMP into remote database
>> Database imported succesfully

Seems ok but when i enter the staging url the database is not updated. I thought the task upload the new db into my server.

am i wrong?

mysqldump: command not found
