Installed wireshark from the 15.2 repo but it will not run as follows:

foo@bar:~> sudo wireshark 
[sudo] password for root:  
qt.qpa.xcb: could not connect to display  
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. 
error: XDG_RUNTIME_DIR not set in the environment. 
Failed to create wl_display (No such file or directory) 
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" in "" even though it was found. 
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. 
 
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb. 
 
Aborted

Is there a fix?

TIA!

Same here with sudo, but with su it works…
