How to fix the issue with Wireshark not showing any interface in linux?

If when you start Wireshark complains that you don’t have any interfaces just execute the following commands

sudo addgroup -quiet -system wireshark
sudo chown root:wireshark /usr/bin/dumpcap
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
sudo usermod -a -G wireshark $USER

After this just start Wireshark and it you will have your interfaces back.
