Failed to connect to Mir

Is this on Ubuntu Linux?

Maybe you need to install Wireshark on the machine that you are remoting from? Dunno.

I asked not just about Linux, but specifically about Ubuntu Linux, because "Mir" is the name of a display server for Linux, being developed for Ubuntu, as a replacement for X11.

The error probably means you're running it on an Ubuntu machine, but not from a GUI session on that machine, and it's therefore failing to connect to the Mir server on that machine. Presumably the command you added was one to try to get it to connect via X11 to the machine on which you had the GUI session.

i just added -X to my ssh labpc1 /directory/wiresharkScript.sh and it worked ..is that correct or it's not the best solution ?

I.e, you did ssh -X labpc1 /directory/wiresharkScript.sh?

If so, my guess is that the -X flag, by enabling X11 forwarding, causes the DISPLAY environment variable to be set, so that it refers to the machine from which you're doing the ssh, when wiresharkScript.sh is run, causing Wireshark to be run with the DISPLAY environment set.

This probably means that the Mir/X11 client libraries that Wireshark uses - or, rather, that GTK+, the GUI toolkit Wireshark is using, uses - will, instead of trying to contact the local Mir server (which fails in the fashion you reported), try to contact the X11 server on the machine from which you did the ssh, so that it opens windows on that machine.

I am facing similar same exception on Ubuntu 15.04. My Ubuntu machine is on EC2 Instance(Amazon web services) do not have display/GUI.

Will above solution work in my case also?
