Synology: Frontend does not start due to eventlet

I have been trying to install HA onto my Synology DSM215j without luck thusfar. I followed the guide https://home-assistant.io/getting-started/installation-synology/ and https://community.home-assistant.io/t/error-starting-home-assistant-on-synology-for-first-time/917/3, but i get this in my logfile:

16-06-11 14:08:14 homeassistant.util.package: Attempting install of eventlet==0.19.0
16-06-11 14:08:24 homeassistant.bootstrap: Not initializing http because could not install dependency eventlet==0.19.0

I have tried to install this eventlet manually using

python3 -m pip install eventlet

but that fails to

does somebody know how to solve this issue?

Same problem found on synology 212j, greenlet is failing…

https://github.com/home-assistant/home-assistant/issues/2261

this helped me forward…apparently the newest version of home assistant requires some component that needs to be compiled, and the synology doesnt have the required packages

I fixed it for now by installing the older version v0.20 of home assistant
