Error: Failed to retrieve PID of executing child process

Thanks for the help!
Here is the output of findmnt


Do I still need to do something :grinning_face_with_smiling_eyes:?

(I don’t open these forums very often)

We’ll be releasing a new set of stable release next week which will include the fixes from @brauner.

Thank you for the new release. It is very helpful to see unseen errors.
Here are the updates:

When i tried to find in lxc.log, i found this.

Also, i tried to use lxc monitor --pretty, and found new unseen error.

EROR[07-19|11:42:31] Error calling 'lxd forknet instanceType=container pid=186596 project=default err=β€œFailed to run: /snap/lxd/current/bin/lxd forknet info – 186596 -1: Failed setns to container network namespace: No such file or directory” instance=edc-db

Then, this is the last state

Is the error refer to cgroup or something? *cmiiw

Can you please show lxc info?

Yes, here is the output of lxc info

please let me know if you need something that i miss, so I can provide it

Sorry, I meant lxc info output withou any arguments. So just the ouput of pure lxc info.

Sorry, i misunderstood.

Here is the output.

You’re still on 4.0.9 and not on the newly tagged 4.0.10. It’s likely that it’ll be a few days until @stgraber has released a new LXD version and it has made it to the stable channels.

Alright. Thank you kindly

Hi

I want to update that I’m on 4.0.10 tagged.

Is it already on stable channels?

Thanks in advance.

Yep, LXD 4.0.7 is in the stable channel and comes with LXC 4.0.10 as shown here.
