Actually, you should download the file here. Then before you install, you should do this first :


$ sudo su
#  apt-get install liblua5.1-0
# apt-get install python-pysqlite2
# apt-get install python-paramiko
# apt-get install libctemplate0
# apt-get install libzip1

Then after it, you could just double click on mysql-workbench you had download before.
