Eddy,
Before 6.0 there was a binary installer that worked great for folks that were new to the platform or people who just wanted the installer to do a bit of work for them (there are definitely those that absolutely hated the installer).
Now, in 6.0, you can either use Docker, which not everyone likes to use, or you can install manually, which is what it sounds like you are trying to do.
Have you seen this: GitHub - loftuxab/alfresco-ubuntu-install: Alfresco script based install for Ubuntu
You might want to give it a try. It installs Alfresco the way Loftux likes to install Alfresco. If that meets your needs, then great! If it doesn't, you can use the install as a working example and make tweaks to customize as needed.
Jeff
