Great, thanks for testing, that means we'll have to backport Julien's patch to the stable packages earlier than expected!<br>
<br>
I'll try to update these this afternoon, I'll keep you posted.<br>
<br>
Cheers,<br>

No it didn't install correctly.It is generating a crash report and<br>
lttng-module-dkms exists in it too.<br>

Hi,<br>
<br>
Could you just do<br>
$ sudo apt-get install --reinstall lttng-modules-dkms<br>
<br>
and check in the output if you have any errors, or if it really installs<br>
successfully?<br>
<br>
Maybe Ubuntu's patches already trickled down to 12.04 and you might be<br>
hitting <a href="https://bugs.lttng.org/issues/814" target="_blank">https://bugs.lttng.org/issues/<u></u>814</a><br>

I removed all LTTng packages from the system by manually searching in dpkg<br>

sudo apt-get install lttng-tools lttng-modules-dkms babeltrace<br>

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

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

I am having a problem in generating a kernel trace using the latest<br>
<br>
LTTng on Ubuntu 12.04.<br>
<br>
It was working fine previously but when I updated LTTng it stopped<br>
<br>
generating the trace contents. I did an uninstall and reinstall but it<br>
didn't work either.<br>
------------------------------<u></u>------------------------------<u></u>----------<br>
<br>
Please define what you mean by "the latest LTTng". What are the<br>
versions? ($ lttng --version, $ lttng-sessiond --version)<br>
