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
> # default behavior for the release upgrader > # > > [DEFAULT] > # 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.
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";
