I'd thought to upgrade from Ubuntu 16.04.4 to 16.04.5 you needed to run "sudo apt-get dist-upgrade".
I just ran
sudo apt-get update
sudo apt-get upgrade
and that took me from 16.04.4 to 16.04.5 after a reboot. "history" shows I've never run dist-upgrade.
Did I just misunderstand update+upgrade, paint myself into this corner some other way, and can I down rev back to 16.04.4 ?
Edit to add info: This is the server for a SW team, all of whom are supposed to be on the same revision of tools/compilers/op-system/etc. We're doing embedded development. All of us staying on the current rev is a big deal, so an accidental up-rev is ergo a big deal.
Now if this was expected behavior and it's not a serious upgrade then maybe I can just tell the team and have everyone else upgrade, but it seems like this shouldn't have happened.
Edit again: I meant 16.04.04 -> 16.04.05 NOT 14.04 (My apologizes)
I think this is related to unattended-upgrades
cd /etc/apt/apt.conf.d
more 20auto-upgrades
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";
more 50unattended-upgrades
// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
"${distro_id}:${distro_codename}";
"${distro_id}:${distro_codename}-security";
// Extended Security Maintenance; doesn't necessarily exist for
// every release and this system may not have it installed, but if
// available, the policy for updates is such that unattended-upgrades
// should also install from here by default.
"${distro_id}ESM:${distro_codename}";
// "${distro_id}:${distro_codename}-updates";
// "${distro_id}:${distro_codename}-proposed";
// "${distro_id}:${distro_codename}-backports";
};
I also think deleting 20auto-upgrades would prevent rev changes.
14.0.4.4
to14.0.4.5
is nothing major, just bugfixes and small changes.14.0.4.5
version.sudo apt-get dist-upgrade
at all? The two other commands do not replace it.
