Installation on Ubuntu14.04 hangs

[capoitaly]

Ok guys, thank you for suggestion.
This is what I've done:
- removed apparmor with:
etc/init.d/apparmor stop
update-rc.d -f apparmor remove
apt-get --purge remove apparmor apparmor-utils libapparmor-perl libapparmor1
- installed mysql with apt-get install mysql-server and configured a mysql root password
- commented out line from 128 to 135
- commented out line from 584 to 605
- added these lines before line 607
mysqlpassword="mysql root password configured during install";
MY_CNF_PATH="/etc/mysql/my.cnf"
DB_SERVICE="mysql"

Started install script all works fine!!

Thank you very much!
