Method 1 - Disable for one user
Create a local(user) copy of
update-notifier.desktop
mkdir -p ~/.config/autostart cp /etc/xdg/autostart/update-notifier.desktop ~/.config/autostart/ vim ~/.config/autostart/update-notifier.desktop
Find this line in the local file
X-GNOME-Autostart-Delay=60
Replace with:
X-GNOME-Autostart-enabled=false
Now log out and in again, or kill the running update-notifier:
killall update-notifier

Method 2 - Disable for all users
Do the same as method 1, but instead of modifying a local/user copy, modify
/etc/xdg/autostart/update-notifier.desktop
Manually Check for update
After disabling update-notifier, use Update Manager(GUI), or following command line to check for package update
sudo apt-get update
sudo apt-get dist-upgrade
The first line download the latest package list from repository. The second line will show all installed packages with update available.
Solution 2
If you're running a server install of Ubuntu with a very limited RAM configuration, I'd suggest you disable completely the automatic actions from update-notifier. You could even remove this package.
However you might still want some automatic updates to run to ensure your system gets the security fixes. One very lightweight and handy tool to do that on a server is cron-apt, it can notify you of updates through email.
Here are some instructions to install and configure it to your needs. This article on Debian Administration is also worth reading.

On Ubuntu 12.04 LTS, with server of 512MB RAM, the
apt-check
is using up to 250 memory and cause my system to un-usable every night, e.g.ps ax | grep apt 14895 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14896 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14899 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14902 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14906 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14912 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14913 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14914 ? DN 0:01 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14915 ? DN 0:01 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14916 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14917 ? DN 0:01 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 14920 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 15299 ? DN 0:01 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 15302 ? DN 0:02 /usr/bin/python /usr/lib/update-notifier/apt-check --human-readable 16368 pts/0 D+ 0:00 grep apt
What the heck this script is running multiple time and eating my system resource? There is a bug here [1] which is confirmed but without any resolution. I am a little surprised that this bug is critical and exists in the LTS, sigh...
Anyway, Not sure when the ubuntu team is able to fix, Any idea how to do it by us?
