To avoid accidental updates of Zimbra packages together with regular system updates, these can be marked for hold via the command apt-mark hold 'zimbra-*' Zimbra updates can be installed via an explicit apt-get upgrade --ignore-hold --only-upgrade 'zimbra-*' Upgrading using the installer will fail though unless an explicit apt-mark unhold 'zimbra-*' was executed beforehand. This patch makes the installer ignore the hold states so updates go more smoothly. This only affects Debian/Ubuntu for Red Hat/CentOS a similar logic would have to be implemented.

I tested this on Ubuntu 16.04 and via the manpages I verified that the added options
--ignore-holdforapt-getand--force-holdfordpkgare available on Ubuntu 14.04 as well.
