-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
In order to trace the kernel, you need the LTTng kernel modules available in the package "lttng-modules-dkms". So make sure you have these three packages installed: # sudo apt-get install lttng-tools lttng-modules-dkms babeltrace The error message you got indicates that there is simply no LTTng modules loaded. Please make sure they are loaded and if the problem persist, let us know! Thanks!
