Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe) and found some lint.

Here's what I've got...

For recipe:

• The outputs section contained an unexpected subsection name. skip is not a valid subsection name.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@isuruf would you be willing to merge this PR? It would be quite nice to release micromamba 1.0 with updated curl (& libarchive) :)

[wolfv]

I think that didn't work in the past:

• you removed darwin-ssl: https://github.com/conda-forge/curl-feedstock/pull/91/files
• because it was crashing git and other tools with older macos versions: https://github.com/conda-forge/curl-feedstock/issues/89

[isuruf]

How about the default being ---with-openssl --with-secure-transport -with-default-ssl-backend=openssl and then micromamba can use secure-transport by default?

[wolfv]

Happy to try that.

[isuruf]

curl_global_sslset is the function to do that.

[wolfv]

yeah, we're using that function already https://github.com/mamba-org/mamba/blob/c5d73a204b19311114885f3081b86e7d881e151e/libmamba/src/core/fetch.cpp#L45-L49
