I think so...

Is this from a VM you built yourself?  What's the output of:

$ pharo --version

I just downloaded:

$ curl http://get.pharo.org/50+vm | bash

And it started without problem.

The VM is dated Wed May  4 11:54:28 CEST 2016.

Occasional bugs aside, my understanding is that V5.0 VMs will work with
V5.0 images.  They should at least start up OK.
