+{{book.project.name}} uses DBus-Java under the covers to communicate at a low level with D-Bus which depends on  http://www.matthew.ath.cx/projects/java/[Unix Sockets Library]. There's a RPM for this library https://github.com/keycloak/libunix-dbus-java/releases[here]. Before installing it, make sure to check the RPM signature:
+
+  $ rpm -K libunix-dbus-java-0.8.0-1.fc24.x86_64.rpm
+  libunix-dbus-java-0.8.0-1.fc24.x86_64.rpm:
+    Header V4 RSA/SHA256 Signature, key ID 84dc9914: OK
+    Header SHA1 digest: OK (d17bb7ebaa7a5304c1856ee4357c8ba4ec9c0b89)
+    V4 RSA/SHA256 Signature, key ID 84dc9914: OK
+    MD5 digest: OK (770c2e68d052cb4a4473e1e9fd8818cf)
+  $ sudo yum install libunix-dbus-java-0.8.0-1.fc24.x86_64.rpm
