-Debian wheezy (stable) and previous versions are not supported; you
-need to build and install LTTng packages
-[from source](#doc-building-from-source) for those.
-
-Debian jessie (testing) and sid (unstable) have everything you need:
+Debian "stretch" and Debian "sid" have LTTng-modules 2.7 and
+LTTng-UST 2.7 packages:
<pre class="term">
-sudo apt-get install lttng-tools
sudo apt-get install lttng-modules-dkms
sudo apt-get install liblttng-ust-dev
</pre>
+
+LTTng-tools 2.7 still needs to be
+[built from source](#doc-building-from-source).
+
+If you need to trace [Java applications](#doc-java-application), you
+need to install the LTTng-UST Java agent also:
+
+<pre class="term">
+sudo apt-get install liblttng-ust-agent-java
+</pre>
+
+If you need to trace [Python applications](#doc-python-application),
+you need to install the LTTng-UST Python agent also:

+<pre class="term">
