I am running Wireshark 3.6.2 on Ubuntu 22.04 as root. In the past, I would see the source and destination IP addresses and the protocol. Now, I can see none of these. I saw one article that suggested removing the configuration directory (.config/wireshark/...) which I did after closing Wireshark, but this made no difference. I know I am accessing both local and wan sites when I capture, and from my previous experience, I do not recall seeing any captures without both source and destination ip addresses, and recall ARP messages being common - but there are no protocols shown. When I look at the frames, all the protocol and address information seems to be absent. I have just tried removing wireshark and reinstalling it, but the issues remain constant. Any clues as to what is going on/ how to fix this? Many thanks for any help.
