compatibility with Chimera Linux?

[ayushnix]

Is melange compatible with Chimera Linux repositories? It also uses the apk package manager.

I tried building a rust image using the following melange.yml file

package:
  name: agate
  version: 3.3.13
  epoch: 0
  description: "simple server for the gemini protocol"
  copyright:
    - license: "Apache-2.0 OR MIT"

environment:
  contents:
    repositories:
      - "https://repo.chimera-linux.org/current/main"
    packages:
      - "base-files"
      - "ca-certificates"

pipeline:
  - uses: git-checkout
    with:
      repository: https://github.com/mbrubeck/agate
      tag: v${{package.version}}
      expected-commit: 1143fe2ca1d44e545bb540b1d7bd5f2b262e403b
  - uses: cargo/build
    with:
      output: ${{package.name}}
  - uses: strip

update:
  github:
    identifier: mbrubeck/agate
    strip-prefix: v
    tag-filter-prefix: v

and the following command

melange build --ignore-signatures --apk-cache-dir $XDG_CACHE_HOME --arch aarch64 --signing-key melange.rsa melange.yaml

but I got this error

failed to build package: unable to build guest: unable to lock image configuration: resolving apk packages: for arch "arm64": error getting repository indexes: reading index https://repo.chimera-linux.org/current/main/aarch64/APKINDEX.tar.gz: parsing https://repo.chimera-linux.org/current/main/aarch64/APKINDEX.tar.gz: unable to read convert repository index bytes to index struct: gzip: invalid header

It is not at present. apko and thus, melange, only support apk2 packages, while chimera uses apk3.
