What the hell is a "messegebus"?

What ever it is, my Margaux doesn't like the fact that it's not talking to her.

I am a Linux newbie running Kubuntu 8.04, Hardy.

So, it would seem when messagebus went down, it took HAL with it. I thought it originally was just HAL that was down, and got this when I tried to reinstall HAL through aptitude:

Code:

Setting up hal (0.5.11~rc2-1ubuntu8.2) ...

 * Reloading system message bus config...                                                                                                                                          Failed to open connection to system message bus: Failed to connect to socket /usr/local/var/run/dbus/system_bus_socket: Connection refused

invoke-rc.d: initscript dbus, action "force-reload" failed.

polkit-auth: This operation requires the system message bus and ConsoleKit to be running

polkit-auth: AuthorizationAlreadyExists: An authorization for uid 109 for the action org.freedesktop.policykit.read with constraint '' already exists

dpkg: error processing hal (--configure):

 subprocess post-installation script returned error exit status 1

I don't know what other information to give you, so just ask and I'll try my best to help.

Danke im Voraus!

The application is called dbus. It is a service that is started on *most* Linux systems during boot. If something killed the service, you should be able to restart it (and HAL) not reinstall it. Here, it appears, is the problem

Code:

invoke-rc.d: initscript dbus, action "force-reload" failed.

Look into that problem before reinstalling HAL.

thanks for answering!

okay, well, I researched a bit on dbus and found that many people were helped by yet another reinstall, this time of dbus. However, again, this is what I got:

Code:

Writing extended state information... Done

(Reading database ... 156578 files and directories currently installed.)

Preparing to replace dbus 1.1.20-1ubuntu2 (using .../dbus_1.1.20-1ubuntu2_i386.deb) ...

Unpacking replacement dbus ...

Setting up dbus (1.1.20-1ubuntu2) ...

The user `messagebus' already exists. Exiting.

 * Reloading system message bus config...                                      Failed to open connection to system message bus: Failed to connect to socket /usr/local/var/run/dbus/system_bus_socket: Connection refused

invoke-rc.d: initscript dbus, action "reload" failed.

...and there's that line again.

I used 'aptitude reinstall' to produce this.. Since it doesn't like that messegebus already exists, would it be safe to just completely uninstall dbus, then do a fresh install?

Thanks again!

Bump..

Sorry, it's been a few days and I've done more research and tried a couple of other solution hopefuls.. but to no avail.
Does anyone else have an idea or a helping hand? (but thank you, weibullguy) It's becoming a problem;
I've lost my battery monitor, the fan stopped working, and many programs after crashing..

Danke!

Try removing the messagebus user and then see if you can reinstall dbus. I'm not familiar with your package manager, so I don't want to give you bum advice. Removing the messagebus user can easily be reversed if it doesn't help.

If that doesn't work, Google the error message
