Ubuntu 18.04 LTS provides the versions shown below of logwatch, postfix, and postfix-policyd-spf-python. This particular release of logwatch is old, and does not correctly process some of the messages produced by postfix-policyd-spf-python. As a result, reports from logwatch are noisy with false alerts. The current release of logwatch from upstream (7.5.2) contains code which handles the messages involved.

A simple workaround is to extract the .../scripts/services/postfix file and install it under /etc/logwatch, but the reason for using a package manager is precisely to avoid having to make this kind of intervention.

How should this version incompatibility best be escalated to the Ubuntu LTS maintenance (or release engineering) team?

$ apt list -a postfix logwatch postfix-policyd-spf-python

  • Is your system up-to-date? Run `sudo apt update` and `sudo apt upgrade`. Are all of the app's mentioned installed from standard Ubuntu repositories, from 3.part PPA's or other means ? – Soren A Dec 16 '19 at 21:15
  • System is up to date. I run those utilities daily on all my Ubuntu instances. All of the apps mentioned are installed from standard Ubuntu repositories. The problem is that the releases of *postfix-policyd-spf-python* and *logwatch* selected for inclusion are not well matched, as the former produces messages which the latter does not handle correctly. – Niall O'Reilly Dec 17 '19 at 22:01
