I guess that it was in haste what happened. I fixed it. Actually, I did a second time clean install for my webconf, so that I could start with a clean system, only that on the new VM install, the docker has post install ops for Linux and I forgot to do it. So last evening, I did another install with the post install done and everything works just perfectly. Its a clean install of the most recent metasfresh on the github.
I'm all set, sorry for the issue, which is a non issue if the docker is properly installed.
