After changing my Mysql password and trying to upgrade from 2.2.17 to 2.2.19 I noticed the followiing errors: Code: sh: -c: line 0: syntax error near unexpected token `(' sh: -c: line 0: `mysqldump -h localhost -u root -psecretwith()whichfails -c -t --add-drop-table --add-locks --all --quick --lock-tables ispconfig; > existing_db.sql' It appears Ispconfig's upgrade script fails to properly escape the Mysql password in the shell.
