[Koha] cron issue with Koha on Ubuntu

[Mark Alexander]

Excerpts from Steve Nickerson's message of 2017-02-21 12:04:10 -0500:
> The server on all the time, but the problem was that /usr/sbin/anacron didn't exist so the jobs were never kicking off because of the "test -x /usr/sbin/anacron" was of course not finding anacron.

That is surprising. If anacron isn't present, the normal cron takes over via
run-parts, as for example:

> 25 6    * * *    root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )

In other words, it should be possible to run your cron jobs without anacron.
There must be something else missing.  Maybe the cron daemon hasn't been
started; you can see if it is running using:

  ps auxfw | egrep cron

Or maybe it hasn't been installed; this can be checked using:

  dpkg -S /usr/sbin/cron

or

  aptitude search "~i cron"
