@tibequadorian commented on GitHub (Nov 3, 2025):

Turns out this is was due to a bug in pgzip on my very specific hardware (ROCKPro64). I fixed it by installing pigz which podman will prefer to pgzip if installed.
Podman gave me errors on podman pull like almost every time:

Error: unable to copy from source docker://ghcr.io/jellyfin/jellyfin:10.11.2: copying system image from manifest list: writing blob: adding layer with blob "sha256:5fc462b172d49ffa71ac6eb7089c116fcdb406432e9b8cff6d7435b82b787a3b"/""/"sha256:4e996d79fa10b2c5fc810189276ecf04d92619e19fc9388c2b73680ba778f911": ApplyLayer stdout: {"layerSize":183821964}
 stderr:  gzip: invalid checksum

I don't know how I managed to pull it in the end but the image was corrupted somehow so jellyfin segfaulted.

Reproduce the error in pgzip:

skopeo copy docker://ghcr.io/jellyfin/jellyfin:10.11.2 dir:jellyfin-image

Copy the layer that fails to extract (in my case 5fc462b172d49ffa71ac6eb7089c116fcdb406432e9b8cff6d7435b82b787a3b)
to a folder.

Put this code inside the folder.

check_checksum.go:

package main

import (
        "io"
        "log"
        "os"

        gzip "github.com/klauspost/pgzip"
)

func main() {
        f, err := os.Open("5fc462b172d49ffa71ac6eb7089c116fcdb406432e9b8cff6d7435b82b787a3b")
        if err != nil {
                log.Fatal(err)
        }
        defer f.Close()

        r, err := gzip.NewReader(f)
        if err != nil {
                log.Fatal(err)
        }
        defer r.Close()

        if _, err := io.Copy(io.Discard, r); err != nil {
                log.Fatal("Checksum failed:", err)
        }

        log.Println("Checksum OK")
}

Test

$ go run check_checksum.go
2025/11/03 14:40:41 Checksum failed:gzip: invalid checksum
exit status 1
$ taskset -c 0 go run check_checksum.go
2025/11/03 14:40:31 Checksum OK

Using multiple cores results in invalid checksum -> there is bug in the parallel implementation

@tibequadorian commented on GitHub (Nov 3, 2025): Turns out this is was due to a bug in pgzip on my very specific hardware (ROCKPro64). I fixed it by installing `pigz` which podman will prefer to `pgzip` if installed. Podman gave me errors on `podman pull` like almost every time: ``` Error: unable to copy from source docker://ghcr.io/jellyfin/jellyfin:10.11.2: copying system image from manifest list: writing blob: adding layer with blob "sha256:5fc462b172d49ffa71ac6eb7089c116fcdb406432e9b8cff6d7435b82b787a3b"/""/"sha256:4e996d79fa10b2c5fc810189276ecf04d92619e19fc9388c2b73680ba778f911": ApplyLayer stdout: {"layerSize":183821964} stderr: gzip: invalid checksum ``` I don't know how I managed to pull it in the end but the image was corrupted somehow so jellyfin segfaulted. ### Reproduce the error in pgzip: ``` skopeo copy docker://ghcr.io/jellyfin/jellyfin:10.11.2 dir:jellyfin-image ``` Copy the layer that fails to extract (in my case `5fc462b172d49ffa71ac6eb7089c116fcdb406432e9b8cff6d7435b82b787a3b`) to a folder. Put this code inside the folder. #### `check_checksum.go`: ``` package main import ( "io" "log" "os" gzip "github.com/klauspost/pgzip" ) func main() { f, err := os.Open("5fc462b172d49ffa71ac6eb7089c116fcdb406432e9b8cff6d7435b82b787a3b") if err != nil { log.Fatal(err) } defer f.Close() r, err := gzip.NewReader(f) if err != nil { log.Fatal(err) } defer r.Close() if _, err := io.Copy(io.Discard, r); err != nil { log.Fatal("Checksum failed:", err) } log.Println("Checksum OK") } ``` Test ``` $ go run check_checksum.go 2025/11/03 14:40:41 Checksum failed:gzip: invalid checksum exit status 1 $ taskset -c 0 go run check_checksum.go 2025/11/03 14:40:31 Checksum OK ``` Using multiple cores results in invalid checksum -> there is bug in the parallel implementation
