Mailing List signup is now limited to OIDC only
by Greg Sutcliffe 02 Apr '26

02 Apr '26

Hi all, In an effort to combat the increasingly clever spam we get, we have updated our Django AllAuth config to restrict signup to OIDC-only - that is, the signup button now redirects to accounts(.stg).centos.org, and AllAuth will reject signups that try to go to the URL directly. This should not affect older accounts that were created previously, only *new* signups. More details can be found on this issue: https://gitlab.com/CentOS/infra/tracker/-/work_items/1862 - if you have issues signing in to the lists, let us know. Cheers, Greg --- Greg Sutcliffe CentOS & Fedora sysadmin

FYI : announcing end of legacy composes.centos.org infra
by Fabian Arrotin 02 Apr '26

02 Apr '26

Sending here just as a FYI : https://composes.centos.org is being decommissioned today. It was used some time ago for the Stream 8 (EOL itself in May 2024) but doesn't serve any purpose anymore. (https://redhat.atlassian.net/browse/CS-3332) Just to note that it doesn't concern the one that is still used for staged releases for CentOS Stream 9 , 10 (and upcoming 11) , which are available under https://composes.stream.centos.org, and that CDN will continue to be used to access staged content for these releases. So nobody should see any impact with the composes.centos.org decommission phase, as nobody should be using it anyway (old and unsecure content), so just sending this as a FYI -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 17F3B7A1 | @arrfab[@fosstodon.org]

DaVinci Resolve Studio 20 Version 20.3.1 Build 6 Support on CentOS Stream 10
by Turritopsis Dohrnii Teo En Ming 18 Mar '26

18 Mar '26

Subject: DaVinci Resolve Studio 20 Version 20.3.1 Build 6 Support on CentOS Stream 10 Good day from Singapore, According to Blackmagic Design Cloud official website, it mentioned that the minimum system requirements for Linux operating systems is Rocky Linux 8.6 or CentOS 7.3. Can I still install and use DaVinci Resolve Studio 20 non-linear video editing software (NLE) on CentOS Stream 10 with full GPU hardware acceleration? Which NVIDIA GeForce RTX Graphics Processing Unit (GPU) should I buy? I want to use AI Magic Mask - Person mode for AI subject isolation / rotoscoping in 4K UHD 3840 x 2160 videos. My intention is to use Artificial Intelligence (AI) to keep only the female model in the 4K video and remove everyone else (including their faces and bodies) from the 4K video. And of course the background will be removed as well unless I use 2 layers. But processing 2 layers with AI neural engine is extremely time consuming, which may take days. The entire audio track will be muted as well. My intention to use AI subject isolation / rotoscoping is to comply with European privacy laws, in particular the General Data Protection Regulation (GDPR). As I am the poorest man in the whole world living in extreme poverty for the past 48 years of my life, I would like to purchase NVIDIA GeForce RTX graphics cards using Buy Now Pay Later (BNPL) like Atome or Grab PayLater with minimum of 3 monthly installments and up to 12 monthly installments. I bought my vivo X100 Pro 5G flagship Android phone on 19 Dec 2025 Friday using Grab PayLater with 4 monthly installments of SGD$153. My present entry level MSI NVIDIA GeForce GTX 1650 GPU with 4 GB VRAM (video RAM) is too cheap and could not handle the AI workflow and workload. DaVinci Resolve Studio 20 alone would cost SGD$408.75 inclusive of GST (one-time purchase life time perpetual license). I am now evaluating / trying out DaVinci Resolve Studio for SGD$45.78 per month using Cloud Rental License before committing to the full purchase of the video editing software. Another consideration would be Adobe After Effects with monthly USD$20 to USD$30 subscription. I am looking forward to your advice. Thank you very much.

OpenStack RPMs - Call for packaging volunteers
by Francesco Di Nucci 16 Mar '26

16 Mar '26

Hi all, the RDO Project[0], that provided OpenStack RPM packages through the CentOS Cloud SIG, is switching to a container-based approach due to lack of maintainers.[1] This means *there will be no more RPM packages for OpenStack versions after 2025.1/Epoxy unless new maintainers come up*. *This is a call across the EL and OpenStack communities for volunteer maintainers of RPM build pipelines*. If you're interested you can: * Add your name to the dedicated Etherpad (https://etherpad.opendev.org/p/rdo-volunteers) * Register to the RDO devs mailing list (dev(a)lists.rdoproject.org) and ask for more information No previous experience with packaging/pipelines is required, just willingness to learn /Note: this email is being separately to different mailing lists. If you have subscribed to more than one and recieve it multiple times, sorry for the duplication./ Links [0] https://www.rdoproject.org/ [1] https://lists.rdoproject.org/archives/list/users@lists.rdoproject.org/threa… Francesco, another OpenStack on EL operator -- Francesco Di Nucci System Administrator Compute & Networking Service, INFN Naples Email:francesco.dinucci@na.infn.it

Getting a HP Officejet Pro 9120 working with CentOS-Stream 9
by Tony Molloy 05 Mar '26

05 Mar '26

Hi, Subject says it all. I got a HP Officejet Pro 9120e recently and tried to get it setup on a CentOS-Stream 9 machine. I got it on the net and recognized by Cups. In the list of HP printers in Cups there is no entry for the 9120e, so I picked the nearest model, the 9020. Now simplex printing is working fine black/colour. Duplex printing has problems. When I print a two page document to the duplex printer the document prints OK but there is some overprinting/underprinting which makes the printed document unusable. The problem is probably with an incorrect ppd file for the duplex printer. Regards Tony.

Hi guys. Adding something to GRUB_CMDLINE_LINUX= in /etc/default/grub Should that not be reflected in: Command line: BOOT_IMAGE=(hd0,gpt2)/vmlinuz........ I thought it would be but things(some) I add do not show up there. Specifically: fsck.mode & fsck.repair thanks, L.

Memory vs. Display Card
by Rick 28 Oct '25

28 Oct '25

Since memory has become quite cheap lately I decided to move from 2 GB to 6. When I installed the memory every thing was fine until I went to run level 5. At that point the screen turned to garbage and the system froze. Is there a way to fix this so I can use the memory I bought? Do I need a new display card?

Kernels other than Centos' ?
by lejeczek 16 Oct '25

16 Oct '25

Hi guys. Having a kernel from copr's kernel-cachyos added and in: /etc/sysconfig/kernel changing to: DEFAULTKERNEL=kernel-cachyos-lts-core seems to keep that kernel as default entry for grub but.. a newly installed such kernel-cachyos does not make it default - instead old/previous one remains as default. Would you know - ideally without adding hooks/scripts, perhaps it's some configs I'm missing - how to make most recently installed kernel-cachyos default? thanks, L.

SSD for Centos SWAP /tmp & /var/ partition
by Keith Roberts 03 Sep '25

03 Sep '25

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So I had to install another (WD) drive, and repartion it and rebuild my RPM package database, from the backed-up Packages file. That seems to be all OK now. I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat. Here's a short video of a laptop fitted with a SSD drive booting macOS, compared to a similar laptop booting from the standard HDD. The laptop with the SSD boots and loads some apps in 28 seconds. The other one takes twice as long. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro_6G/?utm_source=t… Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

DVD ripper for CentOS Stream 9
by Tony Molloy 02 Sep '25

02 Sep '25

HI, Does anybody know of a good DVD transcoder/ripper which runs on Stream 9/10. I've used HandBrake up to now but it doesn't appear to be in the usual third party repos, EPEL or RPMFusion. I tried flatpak but the version there doesn't include libdvdcss so it can't decode commercial music DVDs. Then I tried snap but there is no snap package available. Any suggestions, then I can finally throw away my 15yo Dell Laptop running CentOS 8. Regards, Tony. Apologies if this is a duplicate.
