    Run wireshark with sudo priveleges - gksudo wireshark. You will need super-user permission to capture packets from your network interface.

  2. This command string worked in my case. I don't run anything as root if I don't have to.

    sudo chgrp your username /usr/bin/dumpcap
sudo chmod 750 /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin+eip /usr/bin/dumpcap
