Question by a relative fah newbie here.

I followed the build RPM instructions on GH, building for the latest verision (V8.5.7), but I must have gone wrong somewhere.

I am able to connect to the client via web control, and the logs look like this, please help me make sense of what is going wrong here

This version is not ready for release, and any problems with it you should ask about on the GitHub.

The current release version is v8.5.5 and can be downloaded from here - https://foldingathome.org/start-folding/

There is a v8.5.6 that was released to internal testing, it may or may not be released to a public beta.

8.5.6 is in public beta and has RPM package and works well

I asked, never got a go-ahead to post it as a Public Beta as there were problems with it.

Thanks for the suggestion, building for an older version (V8.5.5) made it work.

I think the last time I installed fah on my machine I just built for latest, which is why I was surprised it didn't work this time. Guess I got lucky that time

Anyway, I am glad to be back and contributing my machine's idle power to something good now.

Em, it is already available, and has been for a while, and is working fine on variety of systems:
