So I went further and I tested in a VM running Debian 9 - there it works: It looks like I get a Permission denied while building rocko only on Debian 
8, *not* on Debian 9.
Debian 8 is listed as supported on Yocto Project Reference Manual  here: http://www.yoctoproject.org/docs/2.4/ref-manual/ref-manual.html#detailed-supported-distros 
Can somebody confirm this behavior ? It's a straight forward test:

$ git clone -b rocko git://git.yoctoproject.org/poky.git
$ source poky/oe-init-build-env
$ bitbake core-image-minimal

This looks like a weird permission issue rather than something
Yocto-related. How are you running your Debian 8 system? Is it bare
metal, VM, container, some hosting providers VPS, etc?
Indeed, the problem on the Debian 8 machine was that the following command was run sometime in the past - we needed a python service to listen on a privileged port: 
$ sudo setcap 'cap_net_bind_service=+ep' '/usr/bin/python3.5'

Doing a setcap -r /usr/bin/python3.5 fixes the problem.

So it has nothing to do with Yocto!

Thanks for support.



Debian 8 is running on a real system, no VM etc.
I used netinstall with no desktop environment and without all the blows and whistles and added just what I needed, when I needed it. This machine was used for the last 1,5 years or so for developing on Krogoth. I was able to reproduce the problem on a second box, real machine, running Debian 8
Meanwhile I tried building rocko on another real machine, running Debian 9 - it works. ( in the prev email I tested in a Debian 9 VM) 

Thanks



PS I've updated the thread subject to better reflect the problem.

Thanks

Hello,
I have a working krogoth build - I build images etc, everything is fine. Then I wanted to try a rocko build, I installed the needed host packages: http://www.yoctoproject.org/docs/2.4/yocto-project-qs/yocto-project-qs.html#packages 
Then sourced env and bitbake core-image-minimal.
So no extra layers involved, just poky.
I get errors like this:

Any hints ?
