arb-bio does not exist error

[pschloss]

When I try to install arb-bio and arb-bio-tools (individually or together) with conda or mamba, I get the following...

v138_2 $ mamba install bioconda::arb-bio

Looking for: ['bioconda::arb-bio']

Pinned packages:
  - python 3.12.*


Could not solve for environment specs
The following package could not be installed
└─ arb-bio does not exist (perhaps a typo or a missing channel).

The recipe seems to still be live as its page on bioconda. Even looks like it has been getting downloads as indicated by the plot at the bottom of the page at that last link. Ideas?
