Hm? "An error occurred while loading or saving configuration information for dpkg-preconfigure. Some of your configuration settings may not work properly. Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)" Even if I will build jack from svn, at the moment I'll start with testing Debian stable by audio apps provided by the repositories. IMO there's no need to force a user to use D-Bus, when he needs jackd, but ok, might be needed for those who will use session managers? D-Bus is installed by default, so what's missing? As far as I remember, it's the first time, that I'm unable to install jackd from repositories after a clean install, for what distro ever. I installed Debian stable just by using CD-1. Could it be related to this?
