This is my manifest file.

  - name: Elmer
    buildsystem: cmake
    builddir: true
    config-opts:
      - -DCMAKE_BUILD_TYPE:STRING=Release
      - -DWITH_OpenMP:BOOLEAN=TRUE
      - -DWITH_MPI:BOOLEAN=TRUE
    sources:
      - type: git
        url: git://github.com/ElmerCSC/elmerfem.git
        commit: ce800a379786eb8d00d00e826e28e3a8b856a760

What is happening? I can use git clone on my machine to download it just fine.

use a https URL instead.

sources:
  - type: git
    url: https://github.com/ElmerCSC/elmerfem
    commit: ce800a379786eb8d00d00e826e28e3a8b856a760

I use this, still same error.

I think you should specify the branch, because the default branch is devel (instead of the usual master).

I tried

Same error

Can you paste here the full manifest file? Or send a link to a public repository.
So we can test it.

I fixed it just now.
Either use disable-submodules: true to not download submodule.
And upstream must remove unused module.
