wireshark-qt won't launch it's gui with elevated permissions

Deshio · 2024-12-10 22:50:40

I recently switched from using Plasma to using Hyprland and tried to launch wireshark with root privileges but instead I got these error messages and program ceased to run.
https://prnt.sc/3cS4nVYDN8Ks
It's odd because when I try to launch it without the privileges its all alright and works.
Does anyone know possible solutions? I would be thankfull ^^

The solution is to not run wireshark as root.
https://wiki.archlinux.org/title/Wiresh … privileges

The errors are because sudo drops the environment and wireshark doesn't know what display server to connect to.
That's ok - whenever you feel like you need to run some GUI a root/sudo, you made an earlier mistake that lead to that conclusion.
Just don't. Step back and look for the solution that does not involve running some GUI as root.

Thanks for the quick reply!
Won't it affect how the program works although?

Also when I run it with root permissions on KDE plasma it surprisingly works /

If you're using eg. kdesu it might simply preserve the relevant environment, but this is still wrong and wireshark will work fine as long as dumpcap has the proper permissions and you user is member of the wireshark group. The GUI doesn't need elevated privileges at all.

Wireshark requires permissions simply because it captures network packets and stuff so it's not about the GUI.
Alright, it's werid because when I login as root and run the application it works fine.
I know it's not recommended to do it this way but I hope some one one day will have the solution.

When you installed, pacman wrote:

NOTE: To run wireshark as normal user you have to add yourself into wireshark group

Since we'd been there I guess also https://deepl.com/

it's werid because when I login as root and run the application it works fine

There's also absolutely nothing weird about that:

what doesn't happen when you run the entire session as root - what you're not supposed to do either.
