start failed: unsupported shim version (3): not implemented

Description

On arch linux after updating containerd to 2.0.0-1 docker compose won't work anymore this is the error I get

Gracefully stopping... (press Ctrl+C again to force)
Error response from daemon: failed to create task for container: Unimplemented: failed to start shim: start failed: unsupported shim version (3): not implemented

After downgrading containerd to 1.7.23-1 docker compose went back to working as usual.

Steps to reproduce the issue

1. On arch linux upgrade containerd to 2.0.0-1
2. Try to start a container
3. Get shim error

Describe the results you received and expected

I expected everything docker related to work like before the update

What version of containerd are you using?

v2.0.0

Any other relevant information

No response

Show configuration if it is related to CRI plugin.

It seems the containerd daemon was not restarted after the upgrade. Since the shim version shipped with v2.0.0 is bumped to 3, a 1.7 daemon which only supports up to version 2 will not be able to start with it

Hi,
I can confirm both the issue and also that systemctl restart containerd fixes it.
Thank you!

Thank you that fixes it, can't believe I didn't try that.

Hi,

After installation of docker following the official docs (the latest version from Install using the apt repository), I can't seem to run the hello-world container.

I've tried to reboot my machine as well as systemctl restart containerd:

$ sudo docker run hello-world
docker: Error response from daemon: failed to create task for container: Unimplemented: failed to start shim: start failed: unsupported shim version (3): not implemented

Run 'docker run --help' for more information

Environment info:

• Raspberry pi 3B (6.6.62+rpt-rpi-v8 aarch64)
• Debian GNU/Linux 12 (bookworm)
• containerd version 2.0.3

Any idea?
