It's still doing it (on a "security" upgrade today) even though I commented
out the following line(s):
// 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";
};
Happens on another PC, also running Trisquel 7, in spite of the same
commenting to 50unattended-upgrades.
Doesn't matter whether the PC has been restarted after the change or not.
