unbound v1.6.0 python module on debian 9

[Christopher Hearn]

Thanks for the reply George.  When I run what you suggested, I see /usr/lib/python2.7/dist-packages, and the unboundmodule.py is indeed in there.  If I run my python script on it’s own from my shell, it works fine.  unbound itself still does not see it, nor any of the other dependencies in that directory.  Any idea why this might be?

On the newer one, I can?t seem to get unbound to see the python script dependencies.  I do recall on the old server, this was because chroot was enabled.  Once I disabled it in the config file via chroot: ??, it was fine.  It?s disabled on the new one too, but still doesn?t seem to help.  If I symlink the requested file from /usr/lib/python2.7/dist-packages/unboundpython.py to /etc/unbound/, that resolves that error, but more come up because of course it can?t see the other libraries.  This leads me to believe that unbound isn?t looking out of /etc/unbound/ even though chroot is disabled.  Is there something else I?m missing?
