CentOS Showcase
by Shaun McCance 14 Jul '25

14 Jul '25

Hi folks, We're holding another CentOS Showcase on July 28. CentOS Showcase is our half-day virtual conference series that we're trying to do three times a year. The CFP is open until July 21. We'd love to hear what you've been working on. https://www.centos.org/events/showcase-2025-07/ All talks are short, just 20 minutes, including any time you want to leave for Q+A. We run the event from 17:00 to about 21:00 UTC. This time slot best accommodates NA Pacific to EU Central. Apologies to folks outside that range. Round planets are hard. CentOS Showcase is free, but we strongly recommend registering. It helps us a lot with planning. The registration link is on the event page. Thanks, Shaun

Secure boot for CentOS Stream 10 (and soon 9)
by Adam Samalik 10 Jul '25

10 Jul '25

Hi everyone, CentOS Stream 10 now has a working secure boot! This shim-15.8-5.el10 build enabled it earlier this week: https://kojihub.stream.centos.org/koji/buildinfo?buildID=79665 For that to work, the unsigned shim first had to go through a community review: https://github.com/rhboot/shim-review/issues/454 and after that get signed by Microsoft. The signed shim is now available on the mirrors. I'd like to thank Fabian Arrotin for pushing this through and testing, Marta Lewandowska for helping with the review and organization, Nicolas Frayer for all the packaging work, Peter Jones for handling the signing, and Brian Stinson for submitting the initial review. CentOS Stream 9 should have it in the following weeks as well. Cheers, Adam -- Adam Samalik --------------------------- Principal Software Engineer Red Hat

persistent mirror sync issues
by Colin Walters 09 Jul '25

09 Jul '25

Over the last few days it seems like many of the RPM mirrors are desync'd for some subsets of the repo. Many of my builds do `dnf builddep` and the `appstream|baseos-source` repos seem to have an especially high desync rate. $ podman run --rm -ti quay.io/centos/centos:stream10 bash # dnf --disablerepo='*' --enablerepo=appstream-source update CentOS Stream 10 - AppStream - Source 682 B/s | 3.0 kB 00:04 Errors during downloading metadata for repository 'appstream-source': - Downloading successful, but checksum doesn't match.

centos-stream-10 compilation fails on Fedora 42
by mkopelev＠redhat.com 02 Jul '25

02 Jul '25

Hi * I am having difficulties compiling locally centos-stream-10 kernel (https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10) on Fedora 42 x86 machine. I am trying to compile for x86 and aarch64 architectures. I am able to build on RHEL 10,without any difficulties. I am using : make dist-rpms make dist-all-rpms make dist-cross-aarch64-rpms Has anyone had a success in such a compilation?It seems to be impossible without making fixes to the build process

Reminder: Fedora Infra DC move (and impact[s]] on CentOS) next week
by Fabian Arrotin 29 Jun '25

29 Jun '25

As you're probably aware, Fedora announced some time ago (https://communityblog.fedoraproject.org/fedora-datacenter-move-later-this-y…) that they'd move to a new DC. CentOS will also migrate, but majority of our infra is located in a different DC, and so we'll just announce when we'll migrate our own infra there (this year but not this quarter). The updated blog post version (https://communityblog.fedoraproject.org/2025-fedora-datacenter-move-update/) was mentioning new Fedora plans and main ticket to track Fedora work is https://pagure.io/fedora-infrastructure/issue/12603 Fedora migration will happen next week, but let's list potential impacts on CentOS infra, the main one being probably/surely authentication. As you know, we use common authentication for Fedora and CentOS (so FAS accounts are also ACO accounts, same IPA cluster backend) # Authentication We have our own idp instance (https://id.centos.org) that is already running from new DC (migrated today) but we still expect some authentication issues next week when the whole Fedora infra will move from one DC to the other. That's true for things like : - https://accounts.centos.org (an app running in Fedora openshift cluster - that needs to be migrated, equivalent to https://accounts.fedoraproject.org ) => impact: users not able to sponsor/remove other from groups while maintenance is over - https://fasjson.fedoraproject.org (what permits to retrieve users/groups for some services and also TLS certs used to auth against CBS) => impact: services using fasjson endpoint to retrieve users/group membership will fail to sync (like cbs.centos.org, openshift, etc) All CentOS services will remain "up and running" but there will be some delays to reflect authentication changes. So if you'll encounter beginning of next week some small authentication issues, that can explain why (id.centos.org will be up and running but we depend on Fedora infra backend to be itself up and running). # mirrors and CentOS Stream / SIGs content Other potential impact for centos users : CentOS Stream is depending on Fedora mirrormanager to create needed metalinks used in .repo files. As mirrormanager main crawler will be down during the DC move, Fedora and CentOS users will just retrieve metalinks from "cached" information on Fedora proxies (outside of new DC). That means that operation involving dnf would sometimes fail to reflect new content being pushed out, as we don't know Fedora mirrormanager will be back online and with refreshed content set reflected by mirrors crawler. # CBS For SIGs using epel, we expect also issue while waiting for dl.fedoraproject.org to be up and running again. Other SIGs only building for/against CentOS Stream and RHEL will not be impacted -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

make dist-all-rpms fails with test_progs-no_alu32-extras Error
by Sebastian Hetze 18 Jun '25

18 Jun '25

Hi * I recently tried to compile a custom centos-stream-9 automotive SIG kernel and failed. Now I see the very same problem is present in the mainline centos-stream-9 kernel. When I clone the sources from https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9 on a freshly installed centos-stream-9 host, the make dist-all-rpms target fails with make[3]: rsync: Argument list too long make[3]: *** [Makefile:768: test_progs-no_alu32-extras] Error 127 This is certainly not a problem with rsync and the ulimits are definitely sufficient to deal with this ~2000 char argument list. So what is going on here? This rsync call appears to come from the tools/testing/selftests/bpf/Makefile. The problem persists if I BUILDOPTS="-selftests" and I understand bpf to be a SKIP_TARGET by default, anyway. Does anyone have a hint? What is missing or what am I missing?

[Storage-SIG] need a newer libarrow for Ceph Reef
by Tobias Urdin - Binero 17 Jun '25

17 Jun '25

Hello, We’ve always been able to install Storage SIG built Ceph packages without using EPEL9 but when we are testing with the Reef release it looks like we need a newer libarrow that hasn’t been rebuild in Storage SIG since newer thrift 0.15 was introduced. We currently have parquet-libs-9.0.0-1.el9s in Storage SIG [1] but that has been built against thrift 0.14 so requires libthrift-0.14.0.so()(64bit) but we updated thrift to 0.15 a while ago [2] but newer rebuilt libarrow. The rebuild in EPEL9 happend way back in parquet-libs-9.0.0-9.el9 with [3], perhaps we can rebuild libarrow in Storage SIG against current thrift as well to fix this? @kkeithle: any chance you could start a new build for libarrow in Storage SIG? - package librgw2-2:18.2.7-1.el9s.x86_64 from cloud requires libparquet.so.900()(64bit), but none of the providers can be installed - cannot install the best candidate for the job - nothing provides libthrift-0.14.0.so()(64bit) needed by parquet-libs-9.0.0-1.el9s.x86_64 from cloud /Tobias [1] https://cbs.centos.org/koji/rpminfo?rpmID=387534 [2] https://cbs.centos.org/koji/buildinfo?buildID=50735 [3] https://src.fedoraproject.org/rpms/libarrow/c/e1d0139e9685b9ddf29a84a4ba802…

Board Nominations Requested
by Shaun McCance 10 Jun '25

10 Jun '25

** Please read this entire email before responding with nominations. ** We have a process, and the process is important. Recently, Thomas Oulevey announced he would be stepping down from the CentOS Board: https://blog.centos.org/2025/06/reflecting-on-my-centos-journey-a-thank-you… We are asking you, the CentOS community, for nominations for who should fill Thomas's seat. Note that the vote on who will fill this seat is held by the Board itself, but nominations are open to the entire community. If you would like to nominate someone (or self-nominate), please use this Google form: https://forms.gle/B1SPgnxMSb1UDq467 Please DO NOT send nominations to this list. As this is not a public vote, we don't want to give the impression of a popularity contest with public nominations. We also want to avoid any shaming if someone is nominated and is not seated, or chooses not to accept. I will ensure that each nominee is willing and able to serve, and the board will consider them and select the next director from the list. I will also ask each candidate for a brief (100-150 words) blurb about why they would be a good fit for the Board. If you wish to nominate someone, you should consider the list of director requirements and recommendations listed at: https://www.centos.org/about/governance/director-requirements/ Nominations will be open until July 11. SPECIAL NOTE: I have some vacation coming up where I will have limited internet connectivity. For confidentiality reasons, this is one of the few things I do that I can't just delegate when I'm out. I will try to respond to email. I'll return on July 8, a few days before nominations end. If you're self-nominating, or if you know you've been nominated, you can help speed up the process by providing the 100-150 word blurb ahead of time. Thank you for your thoughtful consideration and participation in this process. -- Shaun, for the CentOS Board of Directors
