ECE Installation failing, Timeout

Elastic Orchestration Elastic Cloud Enterprise (ECE)

I think this applies (Limitations and known problems | Elastic Cloud Enterprise Reference [3.6] | Elastic):

  • When you use OverlayFS with Kernel-LT 4.4.156 and later, there is a known regression that prevents Elastic Cloud Enterprise from completing the installation. From the kernel-archive, use Kernel 4.4.155.
