Debian 7.6 was installed on the VM. Default mysql-server which was getting installed using apt-get was 5.5. One of the updates in mysql 5.6 was to support more than one current_timestamp column with default value of current time stamp.
So to install this is what I did
dpkg -i mysql-apt-config_0.3.5-1debian7_all.deb
apt-get install mysql-community-server
