** Description changed:
- ganglia-webfrontend depends on libapache2-mod-php7.0 and on php7.0-xml
- but it is not in the Depends: section in control.
+ [Impact]
+
+ * After installing ganglia-webfrontend, no frontend displays at
+ http://<ip>/ganglia even if the instructions in /usr/share/doc/ganglia-
+ webfrontend/README.Debian are followed.
+
+ * On 16.04, php-fpm is the first listed dependency for the php
+ metapackage. There is no FPM configuration for ganglia and in fact it is
+ only designed to work with libapache2-mod-php from apache (as far as I
+ can tell). Indicate this in the dependencies. In 16.10, for reference,
+ the php dependency order has changed (so libapache2-mod-php is
+ preferred).
+
+ * Also, php-xml is now split out from the core and ganglia-webfrontend
+ needs to explicitly indicate this dependency.
+
+ [Test Case]
+
+ * Install ganglia-webfrontend. Follow the instructions at
+ /usr/share/doc/ganglia-webfrontend/README.Debian to enable the apache
+ configuration.
+
+ * Navigate to http://<ip>/ganglia
+
+ * Without the fixes, raw PHP is displayed (as php-fpm is being used to
+ service PHP requests instead of mod_php7.0). With the fixes, the ganglia
+ web interface is displayed.
+
+ [Regression Potential]
+
+ * The php-xml change has no chance of regression, as the current
+ package errors out otherwise.
+
+ * The dependency order change might have some chance of regression,
+ *if* a user has configured php-fpm correctly to service ganglia-
+ webfrontend. However, this is non-standard and probably implies that
+ user is not using the Debian-provided configuration. In that specific
+ case, as well, I believe installing this newer package will have no
+ impact to their base, as php7.0-fpm satisfies php7.0 satisfies php
+ (which is still an alternative in the affected Depends line).
+
+
+ ganglia-webfrontend depends on libapache2-mod-php7.0 and on php7.0-xml but it
is not in the Depends: section in control.
This leads to errors `Sorry, you do not have access to this resource.

$conf['dwoo_cache_dir']); } catch (Exception $e) { print " ...`
Installing these 2 dependencies fixes it.
1) lsb_release -rd
Description: Ubuntu 16.04 LTS
Release: 16.04
2) apt-cache policy ganglia-webfrontend

3) I expected the dependencies to be installed
4) The dependencies were missing, it was difficult for me to debug
because I am not a php guy. Got help from 'vvuksan' on irc.
