I'm tired of downloading 300mb updates. Windows has done delta updating since XP. It's just silly to download the whole thing if just a few bits of the package change.
updates – When Will Ubuntu Include Delta Updates?

- wait for some time. Then click on third option (try to fix all GPG BADSIG errors)
You need to wait for some time untill its shows you notification that its done ! in case you have upgraded your Ubuntu recently, you have to click on "Re-enable working PPAs after Ubuntu upgrade"
then run
sudo apt-get updateAfter this you can go back to thing you were trying to do.
According to the docs it says to update the settings in /etc/apt/apt.conf.d/20auto-upgrades. So I would update these settings to "0" as well:
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Unattended-Upgrade "0";
But to be super sure you could still edit /etc/apt/apt.conf.d/10periodic and update the following settings to "0":
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
Once you have made the updates above none of the packages managed by APT will be automatically updated including MySQL, Apache and PHP.
It's fine to also set APT::Periodic::Update-Package-Lists to "0" as you can still manually update the package lists when you like with sudo apt update and manually update your packages with sudo apt upgrade.
You shouldn't need to make any updates to /etc/apt/apt.conf.d/50unattended-upgrades.
You may also want to disable snap packages from auto-updating however MySQL, Apache and PHP are usually managed by APT so this shouldn't be necessary if you are only really concerned with those packages not being automatically updated.
Important: Disabling automatic updates also means you won't be receiving important security updates for your system so unless you are in the habit of regularly updating your software packages it's probably best to leave automatic updates enabled.

There is nothing on upgrading via deltas. So, no, as of today there seem to be no plans.
Incremental updates have been introduced to apt around the time of the Dapper release (apt 0.6.44). The ubuntu developer community rejected using them because of incompatibilities with their infrastructure.
Here is a list of everything that's happening, and going to happen, in 11.04 (excluding what is not publicly tracked).
