I have been fairly bad with this techy stuff, and I don't understand some of it. So, pretty much, I got to running it with Super User thingy enabled, but it didn't work. I look it up and got the answer that I need to run one extra command. It is "sudo adduser USERNAME wireshark" And when I do, it says "The group Wireshark is already exists. I tried the command without the Wireshark but it says "Only one or two names allowed." What do I do?

It would help immensely if you gave some info about your environment, e.g. which Linux distribution and Wireshark version.

I do not know what you mean by Linux distribution, but I believe that the version is the newest one.

I also use it on a Chromebook.

Are you using a distribution such as Ubuntu, Debian, Redhat etc.? You can copy and paste the info from the Wireshark menu item; Help -> About Wireshark -> Wireshark dialog that will give us some of the helpful info.

Your username is not a member of the user group that has permission to run dumpcap. Determine which user-groups that can run dumpcap and then add your username to that group. Dumpcap is needed to capture packets.

How do I do that?

To be honest. I am not sure what you try to accomplish here. But it seems that you interpreted USERNAME as a literal text where it should be your user name with which you login.

Better would be to add your user to the wireshark group that allready exists. But these are sysadmin tasks that you should delegate to your sysadmin. And an article like might help you out as well.

Nope, I don't. I put in my username, I just used USERNAME instead since my username is my IRL name. I realize now I should elaborate. When I try running Wireshark, it says "Couldn't run /usr/bin/dumpcap in child process: Permission denied" and I kinda just need help with that at this point.
