+ <p>Also note that you may have trouble installing the <code>grml-debian-keyring</code> package as APT will complain about the missing key. A workaround is to download it directly:</p>
+
+ <pre class="rahmen">
+sudo wget -O /etc/apt/trusted.gpg.d/grml.gpg http://deb.grml.org/repo-key.gpg
+sudo apt-get update
+sudo apt-get install grml-debian-keyring
