=C2=A0 Hi,

Could you just do

and check in the output if you have any errors, or if it really installs successfully?

Maybe Ubuntu's patches already trickled down to 12.04 and you might be<= br> hitting htt= ps://bugs.lttng.org/issues/814

I removed all LTTng packages from the system by manually searching in dpkg<= br> and reinstalled it as follows:

The ppa in the system is: http://ppa.launchpad.net/lttng/ppa/ubuntu=

Now, I get the following error:
sudo lttng list -k
Error: Unable to list kernel events: Kernel tracer not available
Error: Command error

I have encountered this problem on two different systems running Ubuntu
12.04, after the update of system and LTTng
