pkg: wireshark-3.0.6 conflicts with tshark-3.0.6 (installs files into the same place).  Problematic file: /usr/local/bin/capinfos

It detected that pre-existing wireshark conflicted, then went ahead and downloaded the new wireshark pkg (without mentioning it was going to try and upgrade wireshark), reinstalled pkg, installed tshark, then attempted to upgrade wireshark.
