Highlights of the week

Infrastructure & Release Engineering

Goal of this Initiative

Purpose of this team is to take care of day to day business regarding CentOS and Fedora Infrastructure and Fedora release engineering work.
It’s responsible for services running in Fedora and CentOS infrastructure and preparing things for the new Fedora release (mirrors, mass branching, new namespaces etc.).
The ARC (which is a subset of the team) investigates possible initiatives that CPE might take on.
Planning board and docs.


Fedora Infra

  • New version of FMN released – removal of python-fedora requirement and all FAS2 calls
  • (almost) all builders reinstalled with f36 and bvmhosts moved to RHEL9 or Fedora36. There’s a few arm buildhw’s to be done after the mass rebuild.
  • FMN (py2) caught up finally, still needs fas2. Looking to switch to FMN (py3) soon.
  • Some recent rabbitmq / fedora-messaging cluster problems. Gave it more memory and hopefully it’s happy again.
  • Finally got * ssl cert working with “FUTURE” encryption.
  • 5 new aarch64 machines and ½ new shelf of netapp storage arriving soon.

CentOS Infra including CentOS CI

  • Mirror requests
  • Duffy migration tasks
  • Business as usual

Release Engineering

  • Mass rebuild starts later this morning (Wed 20th) unless any last minute delays.

CentOS Stream

Goal of this Initiative

This initiative is working on CentOS Stream/Emerging RHEL to make this new distribution a reality. The goal of this initiative is to prepare the ecosystem for the new CentOS Stream.


  • A Stream 8 compose has been pushed to correct some repoclosure issues with the kernel
  • Lots of PTO

Package Automation (Packit Service)

Goal of this initiative

Automate RPM packaging of infra apps/packages.


  • Datagrepper is with packit
  • Mirrormanager2 in progress

Flask-oidc: oauth2client replacement

Goal of this initiative

Flask-oidc is a library used across the Fedora infrastructure and is the client for ipsilon for its authentication. flask-oidc uses oauth2client. This library is now deprecated and no longer maintained. This will need to be replaced with authlib.


  • Pull request is in
  • Worked through the comments/suggestions from Aurelien
  • NEED EXPERIENCED TESTERS (to help write tests, need to update existing tests, scenario is complex, mocking out Ipsilon responses etc feel free to join)


Goal of this initiative

Extra Packages for Enterprise Linux (or EPEL) is a Fedora Special Interest Group that creates, maintains, and manages a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL).

EPEL packages are usually based on their Fedora counterparts and will never conflict with or replace packages in the base Enterprise Linux distributions. EPEL uses much of the same infrastructure as Fedora, including buildsystem, bugzilla instance, updates manager, mirror manager and more.


  • EPEL9 is up to 6608 (+266) packages from 3083 (+127) source packages
  • Sponsoring of new packagers with interest in EPEL
  • Add python-tenacity to resolve ansible-lint fail to install bug
  • Notable package additions:
  • keepassxc
  • asciinema

FMN replacement

Goal of this initiative

FMN (Fedora-Messaging-Notification) is a web application allowing users to create filters on messages sent to (currently) fedmsg and forward these as notifications on to email or IRC.
The goal of the initiative is mainly to add fedora-messaging schemas, create a new UI for a better user experience and create a new service to triage incoming messages to reduce the current message delivery lag problem. Community will profit from speedier notifications based on own preferences (IRC, Matrix, Email), unified fedora project to one message service and human-readable results in Datagrepper.
Also, CPE tech debt will be significantly reduced by dropping the maintenance of fedmsg altogether.


  • Early days – pre-planning talks done today
  • Scoping/research/fact finding from the arc investigation
  • Possibility of using Vue instead of React on frontend, typescript vs javascript also a possibility, FastAPI for the backend API

Kindest regards,
CPE Team
