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

  • F34/F35 container builds failing due to 32bit arm ( )
  • git -core change broke koji. Downgraded git and upstream koji already has a fix.
  • Got a FMW macos build fully signed and notarized! Unfortunately, now need to find out how to build it to be able to run on older macos. ;(
  • Fedora 36 release went pretty smoothly, we are now out of Freeze
  • Business as usual, misc tickets, etc.

CentOS Infra including CentOS CI

  • CentOS Stream storage migration spike (Netapp for nfs/iscsi)
  • Duffy fixes and tests
  • Investigating hardware issue on CI pool
  • Investigating decommission steps
  • pagure upgrade/migration (blocked, waiting on internal Red Hat Team)
  • Updated sshd host key signing (sha1 issue for el9 ssh clients)
  • Bussiness as usual (mirrors, tags)

Release Engineering

  • F36 is out
  • Firmware win binaries signed
  • Bussiness as usual – stalled epel packages, package unretirements

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.


  • Finished the RPM import for c8s to Stream Koji
  • Business as usual otherwise

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 tests
  • Per tenant session lifetimes
  • Some bug fixes

Package Automation (Packit Service)

Goal of this initiative

Automate RPM packaging of infra apps/packages


  • The team is hitting lots of dependency and sub dependency issues, working through them but its slow
  • fasjson-client is our first package to be fully automated
    • upstream release -> src.fp.o PR -> koji -> bodhi
  • Thanks to Nils, Aurelien and Kevin for their help/advice
  • fedora-messaging, datagrepper, fasjson currently being worked on (all have deps issues)
  • spec files will be staying downstream, packit has a way to facilitate this

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.


  • Setup dev environment (Work In Progress!)
  • Starting to implement flask-oidc api using authlib.


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 2568 source packages (increase of 113 from last week).
  • Added rhel+epel-9 mock configs to mock-core-configs.
  • Updated slurm in epel7 and epel8 to fix CVE-2022-29500 and CVE-2022-29501.
  • Retired swtpm and libtpms from epel8 because they were added to RHEL8.6.
  • Added python-texttable to epel9 to allow c8s maintainers (Johnny) to run c9s as a workstation.
  • Added missing devel packages for cogl, clutter, and clutter-gtk to epel9 to unblock other epel9 requests.

Kindest regards,
CPE Team
