    Could you do a search for this file and make sure it exist ?<br>
    <br>
    Also it might be a good idea to uninstall everything (lttng-ust,
    lttng-tools, lttng-modules) make sure that you install the same
    version (stable 2.8 from git if you can) for all three.<br>
    <br>
    I also requested access board on <a class="moz-txt-link-freetext" href="http://open-estuary.org/">http://open-estuary.org/</a> to test it
    myself.<br>
