I upgraded to 25.0.11-ci12 and have the problem. Its even worst then before, the workaround doesn't work any time.

I dump the schema from the Database. The Function looks nearly identical. Only the varchar sizes are different.

CREATE FUNCTION public."DockerBlobs_CreateOrUpdateBlob"("@Feed_Id" integer, "@Blob_Digest" character varying, "@Blob_Size" bigint, "@MediaType_Name" character varying DEFAULT NULL::character varying, "@Cached_Indicator" boolean DEFAULT 
NULL::boolean, "@Download_Count" integer DEFAULT NULL::integer, "@DockerBlob_Id" integer DEFAULT NULL::integer) RETURNS integer
    LANGUAGE plpgsql
    AS $$
BEGIN

    SELECT "DockerBlob_Id"
      INTO "@DockerBlob_Id"
      FROM "DockerBlobs"
     WHERE ("Feed_Id" = "@Feed_Id" OR ("Feed_Id" IS NULL AND "@Feed_Id" IS NULL))
       AND "Blob_Digest" = "@Blob_Digest";

    WITH updated AS
    (
        UPDATE "DockerBlobs"
           SET "Blob_Size" = "@Blob_Size",
               "MediaType_Name" = COALESCE("@MediaType_Name", "MediaType_Name"),
               "Cached_Indicator" = COALESCE("@Cached_Indicator", "Cached_Indicator")
         WHERE ("Feed_Id" = "@Feed_Id" OR ("Feed_Id" IS NULL AND "@Feed_Id" IS NULL)) 
           AND "Blob_Digest" = "@Blob_Digest"
        RETURNING *
    )        
    INSERT INTO "DockerBlobs"
    (
        "Feed_Id",
        "Blob_Digest",
        "Download_Count",
        "Blob_Size",
        "MediaType_Name",
        "Cached_Indicator"
    )
    SELECT
        "@Feed_Id",
        "@Blob_Digest",
        COALESCE("@Download_Count", 0),
        "@Blob_Size",
        "@MediaType_Name",
        COALESCE("@Cached_Indicator", 'N')
    WHERE NOT EXISTS (SELECT * FROM updated)
    RETURNING "DockerBlob_Id" INTO "@DockerBlob_Id";

    RETURN "@DockerBlob_Id";

END $$;

and the table schema

Hey Fritz,

a colleague find out that the parameter "--compression-format zstd:chunked" in the podman push command helped.

You can also set this option globally.

# cat ~/.config/containers/containers.conf 
[engine]
compression_format = "zstd:chunked"

Its a workaround, but it helped.

Thanks,
Marc

Hi,

has someone used a debian connector with a debian repository which is in flat repository format
(described here https://wiki.debian.org/DebianRepository/Format#Flat_Repository_Format )

I would too use a repository which came from opensuse build service (https://ftp.gwdg.de/pub/opensuse/repositories/home:/alvistack/Debian_12/). The feed always reported a 404 error.

In the connector i configured ./ as distribution. On an debian server it worked.

Thanks
Marc
