Unattended-upgrade on by default despite selecting no in setup

[Chris B]

I installed Ubuntu Server LTS 16.04 on my server. At the end, it asks the question if it should enable automatic updates. Following options are available: yes, major security updates only, no. I chose no. However, I found out that despite me choosing no over major security updates only, it installed a kernel update last night on its own.

Is this a bug or is this desired to be like this? It feels a bit like Windows if I say no and it updates nevertheless....

Thanks

Confirmed in 16.04 LTS and Yakkety Daily.

How to reproduce:
User Ubuntu Server ISO and at the very last question of the installer, answer "no automatic updates."

Then, after the reboot, check /etc/apt/apt.conf.d/50unattended-upgrades and you will find:

// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}-security";
// "${distro_id}:${distro_codename}-updates";
// "${distro_id}:${distro_codename}-proposed";
// "${distro_id}:${distro_codename}-backports";
};

Since by default the first one is enabled, it will install automatic updates despite having selected "no" during installer.

How is this different from LP: #1591427?

[Chris B (b-christopher-92)]

It is not. The other one can be closed.

Sorry about that.

The other one has a more detailed description so I'll make this a duplicate of that.
