apt-get always running in background

[Dagorath]

Every day I use the top command to check the processes running on my Kubuntu 10.10 system. Every day I find that apt-get is running under the root account and using 100% of the CPU. It'll run forever if I let it but I use "killall" to stop it.

Pressing the "c" key in top shows the command used to start the process and doing that I see that apt-get is being started with "apt-get -qq -y update". The -qq param is for quiet mode and the -y is to answer yes to any questions. The important thing is the update parameter. It seems that some "feature" of Ubuntu is starting apt-get in update mode for me on a daily basis. I installed Kubuntu only 3 days ago and I don't recall turning this "feature" on anywhere.

How can I disable this "feature" and prevent the system from auto-starting apt-get.?

Although a constant 100% cpu utilization figure seems excessive, this is how (I think) that Ubuntu checks for updates. You should be able to disable that by going to System->Administration->Update Manager->Settings and uncheck the "Check for updates" box.

I don't have System -> Administration -> Update Manager. Perhaps you have that on Gnome systems. I am running KDE.

I do have Applications -> System -> Software Management -> Settings and I have the Check for Updates option set to Never but the system still starts apt-get update on a daily basis. Very weird.

Are you running a multi-core processor?

If so when in top press Shift + I - in the default I have seen my processor running at way over 100%

Shift I turns off Irix mode whatever that is and seems to turn on sensible mode!
