@Taranis In PKGBUILD provides should contain mamba. This is required so if another package depends on mamba this package fulfills it. I should also note that not -bin package provides libmamba and python-libmambapy that this one does not and is in conflict with this. It seems like a problem to me as both these packages should provide as same as the other.

@siavoshkc, I don't think this package should provide mamba, because the current AUR mamba package is something completely different from this.

Adding mamba to this package's provides section would cause some confusing conflicts.

@siavoshkc micromamba is a drop-in replacement for mamba (or tiny-version of mamba). You could add aliases for mamba/conda.

Shouldn't the package provide mamba as well?

The check() step fails for me when trying to create the environment, with a filesystem permission denied error.

The full log is this:

Testing with /var/cache/private/pikaur/build/micromamba-bin/src/bin/micromamba

@carlosal1015 Just figured out the cause. I also installed the python-conda package that ships /etc/conda/condarc of the following contents:

envs_dirs:
  - ~/.conda/envs
pkgs_dirs:
  - ~/.conda/pkgs

This file will also be read by micromamba so that the test environment created by run_test.sh is located in ~/.conda/envs rather than MAMBA_ROOT_PREFIX. I'm not sure what's the best option to handle this corner case.

Interesting check passed in a clean chroot minutes ago.

check fails for 1.5.1, the test virtual environment is created in home rather than tmp, then run_test.sh fails to find the python executable.

Hi @carlosal1015, makepkg fails due to moved license file. New location of mamba license file is info/licenses/mamba/LICENSE.

Hi @Melarok, the micrombamba's GitHub release is from build from source. Please refer to https://aur.archlinux.org/packages/micromamba or wait to binaries from here.
