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.
Link to planning board:


Fedora Infra

  • Issues sending email from -> Finally got tls connection reuse working so we didn’t hit their limits.
  • FCOS apps (almost) all moved from ocp3->ocp4 clusters
  • Cleaned up after a bodhi bug left rawhide updates in limbo.
  • Very close to having resultsdb in ocp4 stg working, just some url adjustments left hopefully.
  • Anitya and the-new-hotness messaging schemas were moved to separate repositories

CentOS Infra including CentOS CI

Release Engineering

  • F36 RC composes 1.1 on friday 1.2 yesterday
  • Discussion about where container images live and potential move to

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.


  • Prototyping CI actions for Stream 9 using Duffy system, awaiting onboarding from infra
  • New compose released
  • Upcoming: Reviewing Stream container and image build processes
  • Improvements to the CVE checker have been rolled out
  • Fedora ELN is being used as a prototype for SHA-1 removal in Fedora

CentOS Duffy CI

Goal of this Initiative

Duffy is a system within CentOS CI Infra which allows tenants to provision and access bare metal resources of multiple architectures for the purposes of CI testing.
We need to add the ability to checkout VMs in CentOS CI in Duffy. We have OpenNebula hypervisor available, and have started developing playbooks which can be used to create VMs using the OpenNebula API, but due to the current state of how Duffy is deployed, we are blocked with new dev work to add the VM checkout functionality.


  • Parallelize running provisioning/deprovisioning playbooks
  • More testing and minor fixes

Package Automation (Packit Service)

Goal of this initiative

Automate RPM packaging of infra apps/packages


  • backlog is stocked with plenty of our apps for the time being, more to be added as needed
  • Expect emails, lots of emails
  • fasjson-client, fedora-messaging and datagrepper currently being worked on
  • currently able to build in copr, minus some hiccups
  • we are currently looking at the best way to version. what are the teams thoughts on moving spec files upstream? it makes everything cleaner in packit. thoughts on a postcard please

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.


  • Currently finding all instances of oauth2client code in the current flask-oidc code, mapping functionality to whats available in the authlib library.


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 up to 2416 source packages (increase of 45 from last week)
  • qt5-5.15.3 update in CentOS Stream 8 and 9 has caused update breakages for KDE users on those distros (EPEL8 and EPEL9). Updated packages are being built as we speak.
  • Unblocked python-aiosignal by adding python-pytest-asyncio to EPEL9.
  • Unblocked several openstack packages by adding python-ddt to EPEL9.
  • Resolved python-aiohttp installation issue by adding python-async-timeout to EPEL9.
  • Updated GitPython in EPEL7 to resolve issue with cloning large repositories.
  • Bump release of python-cheetah in EPEL7 to fix upgrade path from python-cheetah in CentOS 7 Extras.
  • Updated incompatible updates policy to reduce minimum time in testing from 2 weeks to 1 week to match regular updates policy.

Kindest regards,
CPE Team
