hi @ColdV please give us more information about your system as well as your configuration for the grafana agent. have you taken a look at the ebpf example in the examples folder?
your kernel is either too old or compiled without CONFIG_DEBUG_INFO_BTF
we will need to add some support for providing custom arbitrary files which can be downloaded https://github.com/aquasecurity/btfhub
