Yes, there is another way.
I abandoned the easy install script back in July because of so many changes to the OS images and the constant moving target of the prerequisites needed to get a successful install. There had also been a great deal of confusion over whether the easy install script would continue to be maintained. So I moved to another install method.
Since sometime near the end of August, I have been using the following install instructions. I only made them an official topic about 3 weeks ago:
.
This set of instructions have not failed in the several months I have been using them. I have 6 sandbox servers and 3 production servers running from these instructions right now.
Even though the title says it installs v13.11, it will install whatever the most recent release version is at the time of installation.
Hope this helps.
