I'm trying to generate an ISO using the distrobox container of bluebuild. I keep running into this error in the middle of building:

[INFO] => Retrieving OS version from ghcr.io/secureblue/silverblue-main-hardened:latest
[ERROR] => Failed:
  × Failed to create ISO

It doesn't provide any more error information than that. I can pull the image just fine with podman, so I don't see what the actual issue is here.

Try using trace logging (

-vv

) to see more information

Ooo I didn't know I could do trace logging. Thought it stopped at the debug logging. Still not showing much. Here's some of the log right before it fails:

[TRACE blue_build_process_management::drivers::podman_driver:619] => PodmanDriver::run(RunOpts {
    image: "ghcr.io/jasonn3/build-container-installer:v1.4.0",
    args: [
        "VARIANT=Kinoite",
        "ISO_NAME=build/<iso_name>.iso",
        "DNF_CACHE=/cache/dnf",
        "SECURE_BOOT_KEY_URL=https://github.com/ublue-os/bazzite/raw/main/secure_boot.der",
        "ENROLLMENT_PASSWORD=universalblue",
        "WEB_UI=false",
        "IMAGE_SRC=oci-archive:/img_src/<buildname>-silverblue.tar.gz",
        "VERSION=43",
    ],
    env_vars: [],
    volumes: [
        RunOptsVolume {
            path_or_vol_name: "<my home>/blue-build-test",
            container_path: "/build-container-installer/build",
        },
        RunOptsVolume {
            path_or_vol_name: "dnf-cache",
            container_path: "/cache/dnf/",
        },
        RunOptsVolume {
            path_or_vol_name: "/tmp/.tmpyy8qcp",
            container_path: "/img_src/",
        },
    ],
    user: None,
    privileged: true,
    rootless: false,
    pull: false,
    remove: true,
    platform: Some(
        LinuxAmd64,
    ),
})

Then this:

"sudo" "--preserve-env" "podman" "run" "--cidfile=/tmp/.tmpfKQdjp/cid" "--privileged" "--network=host" "--rm" "--volume" "<my home>/blue-build-test:/build-container-installer/build" "--volume" "dnf-cache:/cache/dnf/" "--volume" "/tmp/.tmpyy8qcp:/img_src/" "ghcr.io/jasonn3/build-container-installer:v1.4.0" "VARIANT=Kinoite" "ISO_NAME=build/<iso_name>.iso" "DNF_CACHE=/cache/dnf" "SECURE_BOOT_KEY_URL=https://github.com/ublue-os/bazzite/raw/main/secure_boot.der" "ENROLLMENT_PASSWORD=universalblue" "WEB_UI=false" "IMAGE_SRC=oci-archive:/img_src/<buildname>-silverblue.tar.gz" "VERSION=43"
[ERROR blue_build::commands:32] => Failed:
  × Failed to create ISO

That log line before the error is what tries to run. Try running that in your terminal

Looks like nothing happens at all

It's probably running out of space because /tmp is not set to have enough space in your partitioning. You can change the tempdir with

--tempdir
