Unable to run exe from Gnome-Terminal

[karuboniru]

Your Windows build number:

18197.1000

What you're doing and what's happening:

When In Gnome-terminal (tilix had the same problem)

[yan@BOOK-Karuboniru ~]$ ipconfig.exe
<3>init: (217) ERROR: UtilConnectToInteropServer:270: connect failed 2
[yan@BOOK-Karuboniru ~]$

When In CMD.exe ----> run wsl.exe--->run something else

I can call exe programs normally

What's wrong / what should be happening instead:

I didn't test if it behaves the same in WSL1. I am using WSL 2

Calling exe should work fine even in Linux Terminal apps

I think I have found the reason. Different session gives different WSL_INTEROP, and those in Gnone-Terminal or some other gui terminal apps doesn't work.

If I export WSL_INTEROP in wsl started from cmd to Gnome-Terminal, everything works fine. If I do the opposite way, both will stop calling exe programs

[karuboniru]

Actually if I start Gnome-terminal with
ubuntu1804.exe run "cd \"$(wslpath .)\"; source /home/yan/.profile; gnome-terminal"
I will found the wsl instance would have wrong WSL_INTEROP
but if I run ubuntu1804.exe first, and then gnome-terminal. Everything will work.

Found a solution:
add

if [ ! -e "$WSL_INTEROP" ]; then
	export WSL_INTEROP=/run/WSL/`ls /run/WSL/|awk 'NR==1{print}'`
fi

to ~/.bash_profile
and go to Edit -> Profile Preferences -> Title and Command tab check the "Run command as a login shell" option.
Gnome-terminal will work fine in this way.

Hi @karuboniru it seems like you have a solution to your issue! Thank you for your detective work, if everything is working please close out the issue. :)

@karuboniru - I wouldn't suggest that solution. I am working on a fix for this.

Yes. My code "stole" a WSL_INTEROP socket randomly from /run/WSL/. and the socket may close before you exit your Terminal.

Maybe you can provide a persisting socket in next releases?

I experience similar problem in TMUX but not outside it.

<3>init: (4919) ERROR: UtilConnectToInteropServer:300: connect failed 2

I have several _interop files under /run/WSL/. Setting $WSL_INTEROP to some of them would make my terminal hang while few others (mostly ones who show up in 'clean' wsl terminals outside of tmux) would proceed to execute windows .exe files normally.
