I have a number of Ubuntu machines that have unattended-upgrades set up. I am running 11.10 and do not wish to update to 12.04. How can I disable the upgrade dialog (which still pops up after booting the machines) from the command line?

I think you can edit /etc/update-manager/release-upgrades,

> # default behavior for the release upgrader
> #
> # default prompting behavior, valid options:
> #  never  - never prompt for a new distribution version
> #  normal - prompt if a new version of the distribution is available
> #  lts    - prompt only if a LTS version of the distribution is available Prompt=normal
> Prompt=never

You probably want to set it to never.

am i the only one who thinks that is incredibly unclear? "never prompt" sounds like it'll never ask if you want to update or not. – acolyte May 22 '12 at 13:13
Well in my case, this is the desired behavior – Rom1 May 22 '12 at 16:44

I find this gives better granularity


Set all Options to 0 to disable auto updates, but you can adjust as you wish:

APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "0";
