Package: hplip-gui Version: 3.16.8+repack0-2~bpo8+1 I can no longer install or update hplip-gui (3.16.8.+repack0-2~bpo8+1) from jessie-backports because of the missing dependencies default-dbus-sessions-bus or dbus-session-bus.
These packages seem to exist in Stretch/Testing and Unstable/Sid but do not exist in Jessie. This problem may have happend after substituting the dependency dbus-x11 as requested in bug-report 835911 (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835911) with the two dependencies mentioned above. I am using Debian Jessie 8.5 64bit, 3.16.36-1+deb8u1
