[Pkg-utopia-maintainers] Bug#634475: dbus: Fails to install if messagebus user already present.

[Peter Chubb]

Package: dbus
Version: 1.4.12-4
Severity: normal

I did a routine apt-get upgrade, and found that dbus failed to install.

Setting up dbus (1.4.12-4) ...
adduser: The user `messagebus' already exists. Exiting.
dpkg: error processing dbus (--configure):
 subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of udisks:
 udisks depends on dbus; however:
  Package dbus is not configured yet.
dpkg: error processing udisks (--configure):
 dependency problems - leaving unconfigured
dpkg: dependency problems prevent configuration of dbus-x11:
 dbus-x11 depends on dbus; however:
  Package dbus is not configured yet.
dpkg: error processing dbus-x11 (--configure):

dpkg: dependency problems prevent configuration of avahi-daemon:
 avahi-daemon depends on dbus (>= 0.60); however:
  Package dbus is not configured yet.
dpkg: error processing avahi-daemon (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 dbus
 udisks
 dbus-x11

I `fixed' it by killing the dbus daemon, deleting the messagebus user 
and group, and running dpkg --configure -a
