(FYI: There's an open ticket for this "security vulnerability", but no one seems to have done anything about it since it was reported JAN-2010. If the solution above still fails on your system, an alternative is to set the setuid bit for dumpcap (which lets dumpcap run effectively as the owner of the file, which is root in this case): $ sudo chmod 4711 `which dumpcap` Or simply (if you're already at the login shell): $ exit Ubuntu Desktop: $ gnome-session-quit -logout -no-prompt Instead of rebooting, you can logout with this command: These commands work for me with Wireshark 1.6.2 on Ubuntu Server 11.10 (64-bit): $ sudo apt-get install wireshark The dpkg-reconfigure command creates the wireshark group (so you don't need to), but then you need to add your user to the group, and re-login.

To install Wireshark command line tool only execute: dnf install wireshark-cli. For a GUI Wireshark application execute: dnf install wireshark. To Install package called Whireshark using the dnf command. EDIT: The instructions from README.Debian actually do work (except it's missing the step that tells you to log out and then back in). For additional help or useful information, we recommend you to check the official Wireshark website.
