Hi,

It is because your user does not have the correct permissions.

Could you ensure that your user has the correct permissions?

Here's the groups that your user should be a part of:

You'll also need the udev rules in place:

Even odder, sudo wireshark (and doing a bit more installing the same stufff in different folders) and it works. Why sudo?
