Should not the installer set these?
It should when you run the following command, but not by default [1]: $ sudo dpkg-reconfigure wireshark-common Could you please copy the output of it if it fails? Also please copy the output of the following command after the dpkg-reconfigure command set the permissions: $ ls -alh /usr/bin/dumpcap Cheers, Balint [1] https://anonscm.debian.org/viewvc/collab-maint/ext-maint/wireshark/trunk/debian/README.Debian?revision=27070&view=markup
