[lttng-dev] Error: Unable to list kernel events: Kernel tracer not available

[François Belias]

Hello,

When I run the command `sudo lttng list -k`, I get the following error:

```
Error: Unable to list kernel events: Kernel tracer not available.
```

I am trying to build LTTng-modules from the source. I followed the steps
from this website: [LTTng Documentation](
https://lttng.org/docs/v2.13/#doc-building-from-source), but I still
encounter this error. Can someone help me resolve this issue?

Thanks.
