+Upgrading other Packages
+~~~~~~~~~~~~~~~~~~~~~~~~
+
 You may also want to upgrade the rest of your libraries. If you've done a
 good job with your `version constraints`_ in ``composer.json``, you can do
 this safely by running:
diff --git a/cookbook/upgrade/_update_dep_errors.rst.inc b/cookbook/upgrade/_update_dep_errors.rst.inc
new file mode 100644

+Dependency Errors
+~~~~~~~~~~~~~~~~~
+
+If you get a dependency error, it may simply mean that you need to upgrade
+other Symfony dependencies too. In that case, try the following command:
+
+    $ composer update symfony/symfony --with-dependencies
+
+This updates ``symfony/symfony`` and *all* packages that it depends on, which will
+include several other packages. By using tight version constraints in
+``composer.json``, you can control what versions each library upgrades to.
+
+If this still doesn't work, your ``composer.json`` file may specify a version
+for a library that is not compatible with the newer Symfony version. In that
+case, updating that library to a newer version in ``composer.json`` may solve
+the issue.
+
+Or, you may have deeper issues where different libraries depend on conflicting
+versions of other libraries. Check your error message to debug.
