Hi!

I have followed the guide2wsl.com section for installing nerdctl in wsl2 and when I came to https://www.guide2wsl.com/nerdctl/#test-containerd-and-nerdctl-client, nerdctl --version was working but nerdctl images doesn't with error:

FATA[0000] rootless containerd not running? (hint: use containerd-rootless-setuptool.sh install to start rootless containerd): stat /mnt/wslg/runtime-dir/containerd-rootless: no such file or directory.

I have tried to execute containerd-rootless-setuptool.sh install but it fail too with:

[ERROR] Needs systemd (systemctl --user)

But I could say it is running:

$ ps -ef | grep systemd
root 1 0 0 09:18 ? 00:00:01 /sbin/init systemd.setenv=WSL_INTEROP=/run/WSL/14_interop systemd.setenv=WSLENV= systemd.setenv=WSL_DISTRO_NAME=Ubuntu-22.04 --unit=multi-user.target

I know all this stuff is not yours but I would appreciate a lot every help from your side if you can give some idea on how to get nerdctl and, with it containerd runnint in my WSL2 system.

Thank you very much in advance (in case you read this in some moment :-) ).

Hello! This is actually a pretty good way to get a hold of me, I'll have to figure out a better way. Anyways, I have two theories what's happening.

1. maybe containerd isn't running? What happens when you run:

sudo containerd &

Was a socket file created?

file /run/containerd/containerd.sock

It should say:
/run/containerd/containerd.sock: socket

2. My other theory is the user that nerdctl is running as, cannot connect to /run/containerd/containerd.sock, so there are two ways to help. The easiest way is the setuid bit:

sudo chmod +s "$(which nerdctl)"

or you can always run nerdctl with sudo:

sudo nerdctl images

I hope it helps! If you find anything, I'd love to know how you got it working, and I can update the doc if needed.
