Hi, just tried it on Bullseye and two observations:
* the selection dialog "Should non-superuser be able to capture packets?" should make it clearer *how* to answer the choice. I assume this is by pressing "y"/"n" and "enter" ? Something like that worked for me but the makeup of the dialog is more suggestive of a dialog box which usually have other methods of selection. * in my case not even logging out made non-root capture work but it worked after reboot. This may be a peculiarity of Xfce or something else but should be mentioned in the README. Or indeed.. if there is a known workaround to make it work without reboot/logout it would be very nice to mention it there. * how about asking for a list of users to add to the wireshark group during configuration?
