Our wget_verify function uses wget to download a file and then check
the file's hash. If wget fails, i.e. because of a 404 or other HTTP
or network error, we exited setup without displaying any output because
normally there are no errors and -q keeps the setup output clean.
Wrapping wget with our hide_output function, and dropping -q, captures
wget's output and shows it and exits setup just if wget fails.

Passwords must be eight characters long; when passwords are changed via the users page the dialog states that passwords need to be at least four characters but only eight or more are acceptable.
In 0088fb4553 I changed the management daemon's startup
script from a symlink to a Python script to a bash script that activated the new virtualenv
and then launched Python. As a result, the init.d script that starts the daemon would
write the pid of bash to the pidfile, and when trying to kill it, it would kill bash but
not the Python process.
Using exec to start Python fixes this problem by making the Python process have the pid
that the init.d script knows about.

The cryptography package has created all sorts of installation trouble over the last few years, probably because of mismatches between OS-installed packages and pip-installed packages. Using a virtualenv for all Python packages used by the management daemon should make sure everything is consistent.
See #1298, see #1264.
The PHP5 packages have a dependency on (apache2 or php5-cgi or php5-fpm), and since removing php5-fpm apache2 started getting installed during setup, which caused a conflict with nginx of course.
These packages don't seem to be needed by Roundcube or Nextcloud --- Roundcube includes the ones it needs.

To enable users to do custom spam filtering based on score, it's helpful to render the actual spam score as a float in a separate header rather than as part of X-Spam-Status where it only appears in a comma separated list.
* The Mozilla recommendations must have been updated in the last few years.
* The HSTS header must have >=6 months to get an A+ at ssllabs.com/ssltest.
Nextcloud 12 adds a new OC_VersionCanBeUpgradedFrom field to /usr/local/lib/owncloud/version.php which lists
prior NC/OC version numbers, which confuses our check for what the installed version is. Make our regex more strict.
