server showing 0 updates, but Cron job is reporting packages to be updated

**mastablasta** · November 14th, 2017

the setup is that security updates are applied automatically, but no the ones that need dis-upgrade. so i receive this kind of info on email and then trigger them manually:

Code:

apticron report [Tue, 14 Nov 2017 06:01:21 +0100]
========================================================================

apticron has detected that some packages need upgrading on:

        blekbox
        [ 192.168.1.9 ]

The following packages are currently pending an upgrade:

        perl 5.18.2-2ubuntu1.3
        perl-base 5.18.2-2ubuntu1.3
        perl-modules 5.18.2-2ubuntu1.3

========================================================================
Package Details: "blah, blah, blah..."
========================================================================

You can perform the upgrade by issuing the command:

        apt-get dist-upgrade

as root on blekbox

however when i run apt-get dist-upgrade, the system reports there are no packages to update.

even if i run apt-get update first and then upgrade and/or dist-upgrade it still says 0 to update.

what could be causing this? HWE stack is enabled.

Here's an example using perl-modules

Code:

$ rmadison perl-modules
 perl-modules | 5.14.2-6ubuntu2   | precise          | all
 perl-modules | 5.14.2-6ubuntu2.5 | precise-security | all
 perl-modules | 5.14.2-6ubuntu2.5 | precise-updates  | all
 perl-modules | 5.18.2-2ubuntu1   | trusty           | all
 perl-modules | 5.18.2-2ubuntu1.3 | trusty-security  | all
 perl-modules | 5.18.2-2ubuntu1.3 | trusty-updates   | all

The new update was also a security update, so was already applied automatically
