I freshly installed Ubuntu 16.10 and rsync'd a backup of my previous home directory from kubuntu 16.04 to my new install. Things work well, but I have not been able to resolve local addresses despite much trial and error.
All networking seems to be working flawlessly. Internet browsing, DNS lookup of outside addresses, ssh, etc. are great. Locally, I can access machines via ssh with their addresses, but not their names. It all works fine in nautilus/samba, meaning WINS works. The single problem, it appears, is local network DNS. I have avahi-daemon installed and running, as it came with Ubuntu.
I've included some troubleshooting, using <<>> to shorten redundant or correctly working portions.

Note: I've spent a great deal of time looking at "older" solutions, prior to Ubuntu switching to systemd.resolved in 16.10. They have not worked for me and I don't believe this to be a duplicate question to similar ones with prior Ubuntu configurations.
