Can't find most bioconda packages using conda or mamba/micromamba

[pmomadeira]

Greetings everyone,

As of late I've started having a problem when trying to install packages using conda or micromamba, particularly bioconda packages. When I try to download and install a package with conda install or micromamba install I inevitably get an error related to "package cant be found"

When using micromamba:

error    libmamba Could not solve for environment specs
    The following package could not be installed
    └─ blast does not exist (perhaps a typo or a missing channel).
critical libmamba Could not solve for environment specs

When using conda:

PackagesNotFoundError: The following packages are not available from current channels:

  - blast

Current channels:

  - https://conda.anaconda.org/conda-forge
  - https://conda.anaconda.org/nodefaults
  - https://conda.anaconda.org/bioconda

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

This has been happening with a lot of bioconda packages like blast, pysam, samtools, vcfpy, pyvcf etc, and I can't seem to be able to solve this problem. This has been occuring in a M1 MacbookAir with both conda and micromamba up to date, but for some reason is working on a linux machine.

If anyone has an idea about how to solve this problem I would be greatly appreciated. If you feel like you need any more info I'll be glad to add it.

Biconda does not yet support the Arm architecture that M1 uses. You can subscribe to the Announcements issue (#33333) for an update when we start building recipes for osx-arm64.
