The process '/usr/share/miniconda3/condabin/mamba' failed with exit code 1

ubuntu-latest pipelines will use ubuntu-24.04 soon. For more details, see https://github.com/actions/runner-images/issues/10636

Future Miniforge releases will NOT build Mambaforge installers. We advise you switch to Miniforge at your earliest convenience. More details at https://conda-forge.org/news/2024/07/29/sunsetting-mambaforge/.

Mamba support is still experimental and can result in differently solved environments!
