Micromamba errors Hey everyone! I was wondering if anyone has encountered errors such as the ones shown below when running this command: Metaflow command:
Copy code
python transformed_metaflow_pipelines/some_metaflow_file.py --environment=pypi  --branch something airflow create --generate-new-token pipelines/some_metaflow_file.py
Error:
Copy code
2025-10-13 11:32:58.300 Bootstrapping virtual environment(s) ...
    Micromamba ran into an error while setting up environment:
    command '/home/runner/.metaflowconfig/micromamba/bin/micromamba create --yes --no-deps --download-only --safety-checks=disabled --no-extra-safety-checks --repodata-ttl=86400 --prefix=/tmp/tmpixz_p440/prefix --quiet
(omitting a bunch of packagenames that get dumped to stacktrace)
Copy code
returned error (1)
    critical libmamba Unable to read repo solv file 'conda-forge/noarch', error was: unexpected EOF, depth = 3
Unfortunately, this error does not happen everytime this command is run and thus far we have not been able to pin down the exact conditions when this happens, but wondering if someone else has seen this before.

yeah, this issue sounds familiar, let's see if I can find previous cases..
the issue seems intermittent indeed. Does it resolve for you if you try again?
