Week: 2nd – 6th May 2022

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

  • Resultsdb now entirely working in stg ocp4 (Many thanks Leo!)
  • leaned up ssl cert issues
  • Fixed an issue on ipsilon02 that was preventing logins
  • Business as usual tickets (lists, groups, etc)

CentOS Infra including CentOS CI

Release Engineering

  • F36 RC-1.4 is out
  • 1 proposed blocker, GO/NOGO is tomorrow

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.


  • May planning meeting happening now – outlining goals to work towards for the month
  • Active discussion happening on RHEL and CentOS Stream module synchronization. Planning the branch names, stream names and DistroBaker rules.

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.


  • More deployment testing
  • Reverse lookup IPs to get hostnames when provisioning
  • Legacy API: map parameter combinations to pools in configuration rather than hard-coded
  • Node quotas (ongoing)

Package Automation (Packit Service)

Goal of this initiative

Automate RPM packaging of infra apps/packages


  • Business as usual, working through errors with packit configs
  • Ready to try our first full release this week (hopefully) resulting in koji builds and bodhi updates

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.


  • Investigating where oauth2client appears in the code, possible replacement functions in authlib
  • Met with Aurelien this afternoon to gain some of his knowledge


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 2455 source packages (increase of 39 from last week).
  • Qt5 rebuild issue from last week has been resolved in epel9-next, but epel8-next rebuilds are blocked by a CentOS Stream 8 module bug.
  • Partially unblocked azure-cli addition to epel9 by adding python-jwt.
  • Bootstrapped the “testing-cabal” suite in epel9 (python-extras, python-fixtures, python-testresources, python-testscenarios, and python-testtools) (update). This potentially unblocks many new epel9 packages, notably several Openstack client tools and libraries.
  • ImageMagick incompatible upgrade and related rebuilt packages are available in epel8-testing. (Fixes 81 bugs, 69 of them CVE bugs)

Kindest regards,
CPE Team
