[CDash] CDash 2.0.2/PostgreSQL from Ubuntu 15.10 to 16.04

It happened that there was already a test.php at /var/www doing exactly
that (ie calling phpinfo(); ) At first, the rendered page was blank, which
indicated that php was not working properly, as you suggested.

I think the issue originates from the instructions on the CDash wiki page
about Ubuntu 12.04:

$ sudo apt-get install apache2 mysql-server php5 php5-mysql php5-xsl
php5-curl php5-gd

The line above installs for an explicit version of the php packages:
php5 (maybe at the time of Ubuntu 12.04 there was no version-neutral
"php" package mechanism, who knows) With the upgrade to 16.04, which
switched to php7 as the default, somehow the installation became

In order to solve the issue, I tried to install the packages with
version-neutral php names:

$ sudo apt-get install php libapache2-mod-php php-gd php-curl php-pgsql
The following additional packages will be installed:
  php7.0 php7.0-fpm libapache2-mod-php7.0 php7.0-curl php7.0-gd php7.0-pgsql
The following NEW packages will be installed:
  php php7.0 php7.0-fpm libapache2-mod-php libapache2-mod-php7.0 php-curl
php-gd php7.0-curl php7.0-gd php-pgsql php7.0-pgsql

After restarting apache (sudo service apache2 restart), I was able to see
the correct phpinfo page.

Going back to the CDash index page itself, I was able to see a correctly
rendered CDash page. Unfortunately right now I see the CDash install page
because cdash is unable to access the postgresql db. This is probably
another package issue that I still have to investigate.

Thanks again for the diagnostic trick with phpinfo.
