For some reason, early on, when I booted up I had an error about resolvconf in the list of startup processes. I found a post about resolvconf errors that said that for some reason it gets installed without needing to be and can safely be removed.
If you some errors surrounding /etc/resolvconf (not the same as /etc/resolv.conf I think) you might think about removing it and see if that solves it. It did for me.
