  Dear all,
 While updating  the error with following message appears:
 Message did not receive a reply (timeout by message bus) 
Could you provide us with a bit of context?
What is it you're updating & how, distribution, ...?
Google points to Ubuntu and kpackagekit, problems with
Sun Java.
Maybe running aptitude manually (in konsole) would help:
sudo aptitude update
sudo aptitude safe-upgrade
At least, error messages should be rather explicit
there.
If you're using a different distribution, chances are
calling yum (Fedora/RedHat) or yast (or whatever it's
called these days on SuSE) on the console will yield
more information.
  I already tried to solve the problem by looking for a
troubleshooting.
 Does anybody know what to do?
 Thank you
