[HELP] Cannot install buildkit

[dunmorogher]

Hi there,
I am currently using K3s to set up my local environment. After K3s installation, I downloaded buildkit and I tried to install it; so I can use both nerdctl (installed already and it works) and buildkit together.
When I was installing buildkit with /usr/local/bin/buildkitd --oci-worker=false --containerd-worker=true --containerd-worker-addr=/run/k3s/containerd/containerd.sock --containerd-worker-net=host, I got no response from the command; so I had to press Ctrl+d to exit.

My containerd version is containerd containerd.io 1.7.19 2bf793ef6dc9a18e00cb12efb64355c2c9d5eb41 installed by K3s by default; buildkit version is buildkit-v0.15.1.linux-amd64.tar.gz that I downloaded the latest one.

If you could suggest how I can install it? Thank you.
