I was able to duplicate this by *not* installing Ubuntu updates before
installing the Security Onion packages. In this scenario,
securityonion-passenger-conf tries to install before Apache is fully
installed, thus the error. Assuming there were no errors, you should
be able to resolve the error by simply re-running the following
command:
sudo apt-get -y install securityonion-all
To avoid this in the future, please remember to install all Ubuntu
updates and reboot before installing the Security Onion packages as
described on the Installation page.
