That is correct. You must now use Tutor if you want to install the newest releases of Open edX. Is there any reason why you cannot use or do not want to use Tutor? Just curious.
I also tried with lilac.3 release, but faced the same problem.
My persistence with using the native install is due to the fact that I have more than 5 years of experience with native builds and it is a lot easier for me to manage. But I suppose the support for native builds is over now.
Also, another reason regarding not using Tutor, the truth is that I got my hands to it with the maple release early this year, but when I faced my first problems on this release, I turned to their forum for assistance, but no one ever responded to me. I seemed to me then that the Tutor community wasn’t so organized as the community here.
I hope that after this has changed over the last months, because I think that I will need their help from now on.
The support for native builds is indeed over. For people like you or even I who had 7 years of experience with native builds, it can be difficult at times. But there are people willing to help if you ask questions here. Always remember that people will answer on their own time.
The Tutor forum is now closed. All new questions should be posted here.
