I failed to rebuild the Kindling Agent image on Ubuntu 22.10, the specific error is as follows：

I used the source of recompile-module.sh https://k8s-bpf-probes-public.oss-cn-hangzhou.aliyuncs.com/recompile-module.sh

I think the reason for this problem is that the kernel version is too new

[jundizhou]

You can replace the state mentioned in the above code error report with__ state, which can temporarily solve the problem. We will fix the bug in the next version

[WadeZeak]

When is the next version scheduled to be released?

[dxsup]

Have been fixed in the release v0.6.0
