Hi, i have just got an RPS dedicated server through OVH.co.uk, I have installed Ubuntu Server 9.04 and Ubuntu-Desktop.
After Ubuntu-Desktop installed i received this error:

Errors were encountered while processing:
acpid
ubuntu-desktop
E: Sub-process /usr/bin/dpkg returned an error code (1)

I then installed Free-NX so i could view my Ubuntu Desktop remotely.

Free-NX installed correctly but when i log into Free-NX i receive this error:

Internal error: failed to initialize HAL!

I press close on that error but everything seems to work ok.

Now when i go in to Terminal and sudo apt-get install (to install a programme) the programme installs fine and i can use it but after the installation i get the following:

Errors were encountered while processing:
acpid
ubuntu-desktop
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:
Setting up acpid (1.0.6-9ubuntu4.9.04.3) ...
* Starting ACPI services... acpid: can't open /proc/acpi/event: No such file or directory
invoke-rc.d: initscript acpid, action "start" failed.
dpkg: error processing acpid (--configure):

dpkg: dependency problems prevent configuration of ubuntu-desktop:

dpkg: error processing ubuntu-desktop (--configure):

Is their a way to fix these errors, they dont seem to hamper the server in anyway, well not for the things im using it for but would like to fix them.

Thanks in advance for any replies

This seems to be an Ubuntu crafted Linux kernel problem, try installing and booting from another kernel.
However, the problem appears to be that your acpid program is outdated and you are using a recent kernel.

Check firstly if you can find a decent repository from which you can pull a more recent acpid.

If you find yourself in despair and frustration try openSUSE. It could be a better answer for your prayers.

Good luck.

Thanks for the reply, it might be the OVH custom kernal that is used, OpenSuse isnt an option im affraid and i have not got the Linux knowledge yet to try and compile my own kernal.

Will try and find a newer version of acpid and post back.

Ok I seem to have fixed the problem by sudo apt-get remove acpid this told me it was going to remove acpid and ubuntu-desktop I said ok. It then claimed to have removed these but it didn't.

After that all error messages from the terminal went away.

I then rebooted the server and this seemed to solve the HAL issue i had, so all is good:@)
