unattended-upgrades setting does not fit ubuntu repositories

Binary package hint: unattended-upgrades

unattended-upgrades setting in /etc/apt/apt.conf.d/50unattended-upgrades assumes Debian repositories.

Unattended-Upgrade::Allowed-Origins {
        "${distro_id} stable";
        "${distro_id} ${distro_codename}-security";
// "${distro_id} ${distro_codename}-updates";
// "${distro_id} ${distro_codename}-proposed-updates";
};

This setting should be fitted for Ubuntu like below:

Unattended-Upgrade::Allowed-Origins {
        "${distro_id} ${distro_codename}";
        "${distro_id} ${distro_codename}-security";
// "${distro_id} ${distro_codename}-updates";
// "${distro_id} ${distro_codename}-proposed";
// "${distro_id} ${distro_codename}-backports";
};
