I use Ubuntu 12.04.1 64bit. I always used my update settings set to "never check" and then manually check for updates when I need to. But the last week or so I saw that Ubuntu started checking for updates automatically every day. I went to the settings but is was still set to "never check".
So I changed it to "every two days" to see if that will help. Now it check 2 to three times per day automatically.
Why is it ignoring my update settings and automatically checks so randomly every day ?
Edit: Did the following with the help of gertvdijk:
On request checked if I have unattended-upgrades installed and I have.
Used suggested command
sudo dpkg-reconfigure -plow unattended-upgrades to configure it to not do automatic updates.
Proceeded to check file
/etc/apt/apt.conf.d/10periodic for the following settings:
APT::Periodic::Update-Package-Lists "0"; APT::Periodic::Download-Upgradeable-Packages "0"; APT::Periodic::AutocleanInterval "0"; APT::Periodic::Unattended-Upgrade "0";
and all is at zero after the configuration above.
Will monitor and provide feedback if this resolved the problem.
None of the above worked. My system just informed me of updates that is available , so it still is automatically checking.
