Package: unattended-upgrades
Version: 0.93.1+nmu1
(N.B. in the below, I have replaced the domain of my VPS hosting
provider with `<my_hosting_provider>`, for privacy.)
My Debian 9.3 "Stretch" instance is showing a kernel update as being available:
# apt list --upgradable -a
Listing... Done
linux-image-amd64/stable 4.9+80+deb9u3 amd64 [upgradable from:
4.9+80+deb9u2]
linux-image-amd64/stable,now 4.9+80+deb9u2 amd64
[installed,upgradable to: 4.9+80+deb9u3]
I believe `4.9+80+deb9u3` is the same as `4.9.65-3+deb9u2`, a recent
kernel security update (intended to address
[CVE-2017-5754](https://security-tracker.debian.org/tracker/CVE-2017-5754),
aka
[Meltdown](https://en.wikipedia.org/wiki/Meltdown_(security_vulnerability))).
## Default config fails to install kernel security update
The default contents of `Unattended-Upgrade::Origins-Pattern` in
`/etc/apt/apt.conf.d/50unattended-upgrades` is:
Unattended-Upgrade::Origins-Pattern {
"origin=Debian,codename=${distro_codename},label=Debian-Security";
};
With that configuration in place, the kernel security update fails to
be installed:
# unattended-upgrades -v -d

This is against my expectations. I suspect most sysadmins would like
unattended-upgrades, with such an Origin-Pattern in place, to install
kernel security updates.
(If my expectations are somehow misguided, and the behaviour above is
expected by the maintainer of unattended-upgrades, I would be grateful
for an explanation of why that is the case. Alternatively, if a bug is
present but lies outside the unattended-upgrades package - for
instance, if the kernel update was improperly released via a
repository other than Debian-security - then please could you confirm
this, so that this bug report can be re-filed against the correct
package.)
## Modified config installs kernel security update
If I change `Unattended-Upgrade::Origins-Pattern` in
`/etc/apt/apt.conf.d/50unattended-upgrades` to read
Unattended-Upgrade::Origins-Pattern {
"origin=Debian,codename=${distro_codename},label=Debian";
"origin=Debian,codename=${distro_codename},label=Debian-Security";
};
then the security update is found and installed:
# unattended-upgrades -v -d
