The capture session could not be initiated on interface 'enp2s0' (You don't have permission to capture on that device).

Please check to make sure you have sufficient permissions.

On Debian and Debian derivatives such as Ubuntu, if you have installed Wireshark from a package, try running

    sudo dpkg-reconfigure wireshark-common

selecting "<Yes>" in response to the question

    Should non-superusers be able to capture packets?

adding yourself to the "wireshark" group by running

    sudo usermod -a -G wireshark {your username}

and then logging out and logging back in again.
