dbus: Unable to set up transient service directory: XDG_RUNTIME_DIR "/mnt/wslg/runtime-dir" can be written by others (mode 040777)

I am unsure what is causing this to pop up in my terminal every time I start it, but both .wslconfig and .wsl.conf are blank. Could someone help me get to the root of this?

I am also seeing this in my /mnt/wslg/stderr.log:

Same issue for me.

Try this: chmod 0700 /mnt/wslg/runtime-dir

[soliis-jones]

Try this: chmod 0700 /mnt/wslg/runtime-dir

@rodrigoptrln Unfortunately I still have the same error and the mode has reverted to its original value upon WSL restart.

[crramirez]

it is caused by dbus: dbus-launch --auto-syntax

Turning on systemd seems to fix this issue, but might break other stuff:

# sudo vim /etc/wsl.conf
[boot]
systemd=true
