actually i’m came across the first tesseract hackathon and try to build examples mentioned in the tesseract docs. i executed the cmds given there to use podman instead of docker. but at the first try, the build issue happened. i would grateful if anyone kindly help to resolve this issue. thanks in advance.

os: fedora gnome latest

package manager: uv

description of the build issue:
tesseract build examples/helloworld/
[i] Building image …

Thanks for your interest in Tesseracts!

This is likely a DNS/connectivity issue (potentially caused by a firewall) rather than a podman-specific problem. Can we try a few diagnostics first?

Can you run: curl -I https://registry-1.docker.io and share the output?

If that fails you have a DNS or connectivity issue (possibly due to registry access being blocked).

If the above works but Podman still fails, we’ll need to check Podman’s network configuration specifically:
podman login docker.io
podman system connection list

If you are stuck behind a firewall, your main alternatives consist of using default base images available on your system (e.g. fedora:latest, those returned from podman images, or loading your desired pre-downladed image from .tar file with podman load prior to building).

Best of luck with the Hackathon!

Thanks for your reply.

Here is the output I obtained after executing the first command:

curl -I https://registry-1.docker.io

Now I become able to successfully run my first tesseract!!!
