Answer 1

Here you go!

First, configure the debconf database:

echo "wireshark-common wireshark-common/install-setuid boolean true" | sudo debconf-set-selections

Then, install Wireshark:

sudo DEBIAN_FRONTEND=noninteractive apt-get -y install wireshark

You might also want to suppress the output of apt-get. In that case:

sudo DEBIAN_FRONTEND=noninteractive apt-get -y install wireshark > /dev/null
