umfpack not found in conda-forge; Where can I install it from in conda?

[souvikmeister]

Hi,
I am trying to re-install umfpack in a new set up. I see from this link that conda-forge is the channel to use. However, doing conda install -c conda-forge scikit-umfpack returns

  - scikit-umfpack

Current channels:

  - https://conda.anaconda.org/conda-forge/win-64
  - https://conda.anaconda.org/conda-forge/noarch
  - https://repo.anaconda.com/pkgs/main/win-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-64
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-64
  - https://repo.anaconda.com/pkgs/msys2/noarch
  - https://conda.anaconda.org/anaconda/win-64
  - https://conda.anaconda.org/anaconda/noarch```

Also, I did `conda search -c conda-forge *umf*` which returns

confirming either the channel is not there or my conda-forge channel is not seeing it. Is there anything else I need to do to see this package? I confirmed by doing a search on jupyterlab that I am able to see that package in conda-forge. Otherwise, if I am supposed to add this from a different channel, then please advise.

Works fine for me with conda-forge:

mamba search scikit-umfpack

There isn't a package for Python 3.12 yet though: conda-forge/scikit-umfpack-feedstock#36.
