The following NEW packages will be installed:
autopoint debhelper gettext intltool-debian libapache2-mod-php5 libapache2-mod-php7.0 libapparmor1 libasprintf-dev libc-client2007e libgettextpo-dev libgettextpo0

php7.0-readline php7.0-sqlite3 php7.0-xmlrpc php7.0-xsl pkg-php-tools po-debconf shtool

Not sure what causes the php5 stuff inclusion, but this is why I disable apache2 module for PHP5 and enable PHP7.0 module :
a2dismod php5
a2enmod php7.0
service apache2 restart
