Unable to build RHEL10 image with osbuild (composer-cli)

Hello,

I’m trying to build a qcow2 image on RHEL 10.2 using osbuild-composer, but the compose fails immediately.

I created a minimal blueprint file, pushed it to composer-cli and started the build:

[root@build ~]# cat test.toml 
name = "test"
description = "test"
version = "1.0.0"
distro = "rhel-10.2"
[root@build ~]# composer-cli blueprints push test.toml 
[root@build ~]# composer-cli compose start test qcow2
Compose f879ce94-8a8c-4664-82c2-67b38b9c33cd added to the queue

In the logs I can see that the build fails almost immediately:

[root@build ~]# journalctl -u osbuild-composer -n 2
May 21 16:46:17 build.home.arpa osbuild-composer[13707]: No match for group package "firewalld"
May 21 16:46:17 build.home.arpa osbuild-composer[13707]: No match for group package "dracut-config-rescue"

In the JSON file under /var/lib/osbuild-composer/jobs it just says that the build failed:

[{"uuid":"1b96b5fe-27fd-45be-b218-4aefe9667859","image_name":"disk.qcow2","name":"org.osbuild.worker.server","created":"2026-05-21T16:46:14.783667863+03:00","status":"WAITING","options":{},"osbuild_artifact":{"export_filename":"disk.qcow2","export_name":"qcow2"}}],"pipeline_names":{"build":["build"],"payload":["os","image","qcow2"]},"image_boot_mode":"hybrid"},"dependencies":null,"dependents":null,"result":{"success":false,"upload_status":"failure","pipeline_names":{"build":["build"],"payload":["os","image","qcow2"]},"host_os":"rhel-10.2","arch":"x86_64","image_boot_mode":"hybrid","osbuild_version":"174","job_error":{"id":10,"reason":"osbuild build failed","details":"error running osbuild: exit status 1"}},"channel":"","queued_at":"2026-05-21T16:46:18.048826837+03:00","started_at":"2026-05-21T16:46:18.059740882+03:00","finished_at":"2026-05-21T16:46:50.712606888+03:00","expires_at":"0001-01-01T00:00:00Z","retries":0}

I'm on RHEL10.2 running the latest version of osbuild:

[root@build ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux release 10.2 (Coughlan)
[root@build ~]# rpm -qa | grep osbuild
python3-osbuild-174-1.el10.x86_64
osbuild-initrd-174-1.el10.x86_64
osbuild-selinux-174-1.el10.x86_64
osbuild-174-1.el10.x86_64
osbuild-depsolve-dnf-174-1.el10.x86_64
osbuild-composer-core-164-1.el10.x86_64
osbuild-luks2-174-1.el10.x86_64
osbuild-lvm2-174-1.el10.x86_64
osbuild-ostree-174-1.el10.x86_64
osbuild-composer-worker-164-1.el10.x86_64
osbuild-composer-164-1.el10.x86_64

I've been using osbuild for a while now to provision RHEL9 servers for my homelab but I can't seem to make it work with RHEL10.

Do open source contributions improve chances of getting hired at red hat?

I have 16 years of software engineering experience in infra at FAANG. I never contributed to open source. I want to apply for principal software engineer at red hat . Do I need to build my open source credibility on important repos like k8s to boost my chances of getting hired at red hat?

What am I qualified for?

I have some IT experience but seem kind of stuck in my current position and I wanted to get some Red Hat experts opinions on what I should/could be looking for in a new role.

Here is a brief background on my experience:

  • 10 years in the restaurant/bar industry with much of that being manager experience
  • no college degree
  • broke into IT in early 2020 (just before covid)
  • 2 years on Help Desk
  • 2 years doing Desktop Support at another company
  • 2+ years in my current role as a Sys Admin at a small company

Certifications:

  • CompTIA Security+
  • Cisco CCNA
  • RHCSA (planning to start working on RHCE soon)

In my current Sys Admin role, it is a Windows shop at a small company. I maintain a few servers, site-to-site vpn to our other offices, Active Directory, NAS etc but its limited just because it is a small company and I also do desktop support here as well.

At home lately I have been dabbling with a home lab (mostly Windows) to try to mimic a larger enterprise company as well.

I am interested in Linux roles and I am also intrigued by cybersecurity. I plan to relocate to the Greenville, SC area in the near future after landing a new job. With that being said I am going to attend the bsides event in Greenville later this summer.

Do any of you fine people of this group have any recommendations on the types of roles I am qualified for or would be a good fit for? I see so many posts about finding a job with certs but no experience but I wanted to get others thoughts on certs plus my level of experience.

Thanks!

[HEADS UP] A notice for desktop users who want to upgrade to RHEL 10.2.

I confirmed viafastfetch that GNOME desktop has been upgraded to version 49 in RHEL 10.2, and Red Hat has not mentioned this in the Release Notes.

So check your extensions (if you have any) and custom themes before performing a system upgrade — they may break.

Remote exam camera placement

Hi everyone,

I'm getting ready for my rhcsa exam. I've never taken an red hat exam before and want to prepare for it well.

According to the PDF e-book on the remote exam requirements and info you should use an external camera even if your laptop has one built it, and it says specifically that:

"Your face,

hands and keyboard should be visible throughout the exam"

So I'm wondering where the camera should be placed.

If I put it on the laptop lid my face would be visible but not my hands, just like it would if I used the built in camera. And if put it on the lid and point it towards my hands then my face wouldn't be visible.

Should you place the camera on a stand or how should you place it to satisfy the requirement?

Thanks!

cron vs systemd timers for rchsa/ex200

Are you tested on both equally? Or do you use cron more? Or systemd timers more? Or is it more up to your discretion?

Into the Terminal - underrated study source?

I recently found this show on the Red Hat's YouTube channel, and they even have a playlist with historical episodes bunched together. Watched one ep on permissions, and to me this looks like a seriously underrated study resource. They explain the concept and you can lab along.

Although maybe not positioned as RHCSA prep it appears to cover everything needed in the exam objective. Wondering why I don't see this (free) show mentioned alongside other materials.

Also, how often do things change? I found a video in this series on managing SSH but it's from 3 years ago. Will the process have changed since then, or am I good to consume this slightly older content and use it as a study source? I know the root recovery process for RHCSA10 is difference vs v9, but not sure generally speaking how much else changes over time.

I’m preparing for RHCE v10 and I’m a bit confused about the exam environment since it’s new.

​

During the RHCE v10 exam:

Can we use both VS Code and CLI/terminal for solving tasks?

Are we allowed to run all commands directly in the terminal as usual?

Or are candidates expected to mainly use VS Code for editing/playbooks?

Also, does the exam evaluation/checking consider whether VS Code was used or not, or does only the final working solution matter?

Would appreciate responses from anyone who already attended RHCE v10 or has official information. Thanks!

I am a beginner in Linux, and I don’t know how to prepare for and pass the RHCSA exam. Can someone please guide me?

RedHat Interview Timeline / Recruiter GHOSTING

I Interviewed for a Senior Consultant position with RedHat about 2 weeks ago. I have sent follow up emails to the recruiter - no response. Candidates deserve better. We talk about 'candidate experience,' but how can we improve when the bar is on the floor?

If a RedHat recruiter ghosts ME, does it reflect the company culture? Or just a broken process?

What could have went wrong?

Hi guys, I did my rhce today and I was very positive I got most of the question correct, I even verified after running it. However when result came, I got this.

Exam domain number:     20
Passing score:          210
Your score:             24

Result: NO PASS

Performance on exam objectives:

OBJECTIVE: SCORE
Understand core components of Ansible: 3%
Use Roles and Ansible Content Collections: 9%
Install and configure an Ansible control node: 100%
Create Ansible plays and playbooks: 0%
Use Ansible modules for system administration tasks: 0%
Manage content: 22%

I am genuinely curious what could have gone wrong so I could do it in a retest?

Jobs after RHCSA

i just passed my Ex200v93 exam and I am looking for linux sys admin jobs. I want to get into HPC/AI sys admin in the future (like that is my ultimate goal), and I need to start somewhere, most likely as a linux sys admin.

I have a masters in HPC from a top 5 Uni in the UK (from a reputed HPC center). I did land interviews at companies like AMD and NVIDIA, but these roles were senior and requiring 3-5 years of HPC/Limux admin experience, which I clearly do not have.

so... what would you do in my place. I am currently doing a random unrelated job for survival. This job also helped me fund the RHCSA cert so I am greatful. But I am wondering how should I get the actual job?

RedHat developer renewal broken?

I'm having the worst time trying to renew my redhat developer subscription. Has anyone had a similar experience in the last couple of days? Even making a brand new account under a previously unused email, fails to create the subscription.

I spoke with support on it and all they could tell me is their tools don't show any known issues.

Luxembourg systems/cloud engineer salary

Hi everyone,
I was recently contacted by an IT consulting firm (ESN) in Luxembourg for a Junior Systems/Cloud Engineer role (focused on Linux, Kubernetes, Cloud, etc.).
They are asking for my salary expectations, but I'm not entirely sure what to say. After doing some research online and grilling Claude and Gemini, I'm thinking of asking for €54k gross annually.
For context:
• I have 3 years of work-study (alternance) experience working with Linux, including 2 years during my Master's degree at a bank.
• I hold 2 Red Hat certifications: one in OpenShift (so, Kubernetes) and the RHCSA.
• I graduated top of my class for my Master's.

Do you think €54k is a reasonable figure for this market?
