What happened?

Hi there! I'm trying to install a package with characters in the version spec that aren't typical (an exclamation point). This is coming from x264 which is a dependency of ffmpeg which is a dependency of ffmpeg-python which is in turn a dependency of geemap.

When I generate a conda-lock file with this command:
conda-lock --micromamba --check-input-hash -p linux-64 -p osx-64 -p osx-arm64 -f meta.yaml

I get entries like this for the x264 library:

- name: x264
  version: 1!164.3095
  manager: conda
  platform: linux-64
  dependencies:
    libgcc-ng: '>=12'
  url: https://conda.anaconda.org/conda-forge/osx-arm64/x264-1%21164.3095-h57fd34a_2.tar.bz2
  hash:
    md5: 6c99772d483f566d59e25037fea2c4b1
    sha256: 175315eb3d6ea1f64a6ce470be00fa2ee59980108f246d3072ab8b977cb048a5
  category: dev
  optional: true

However, when I try to install these dependencies with conda-lock install --mamba --name=dev-env conda-lock.yml, I get the following error:

ERROR:root:Invalid spec 'https://conda.anaconda.org/conda-forge/osx-64/x264-1%21164.3095-h775f41a_2.tar.bz2 md5=23e9c3180e2c0f9449bb042914ec2200': Invalid version '1%21164.3095': invalid character(s)

When I manually change the conda-lock file to not have a % encoded URL, install works:

Thanks @mhoeger for the very well-written and well-researched report. Your efforts certainly saved me a lot of time.

I passed the issue upstream in mamba-org/mamba#3737. Until this is addressed, I'd recommend downgrading micromamba to 1.5.12. This can be done via the command

micromamba self-update --version 1.5.12
