disable auto_update_conda

[szcf-weiya]

The motivations come from #242 and #238, where the error "ResolvePackageNotFound: - conda==23.1.0" is thrown when conda automatically upgrades from 23.1.0 to 23.5.0.

Although I did not quite understand the real logic of the error, one simple workaround is to disable the auto-update of conda, i.e., fix its version.

On the other hand, since the package Conda.jl has already required to install the latest conda release,

Conda.jl/src/Conda.jl

Lines 167 to 179 in fe6c94c

	if USE_MINIFORGE
	if !(conda_platform in MINIFORGE_PLATFORMS)
	error("Unsupported miniforge platform: $(conda_platform)")
	else
	res = "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-"
	end
	else
	if !(conda_platform in MINICONDA_PLATFORMS)
	error("Unsupported miniconda platform: $(conda_platform)")
	else
	res = "https://repo.continuum.io/miniconda/Miniconda$(MINICONDA_VERSION)-latest-"
	end
	end

I think the later update by auto_update_conda is just minor, like from 23.1.0 to 23.5.0, then disabling such minor aggressive updates should be reasonable. As a byproduct, it can save the upgrade time.

Would be great to have a fix for this issue! Any problems with the PR?

Why are the Windows tests failing?

[szcf-weiya]

I think it is just a simple edit, and should not be related to the platform.

How can we rerun the test? (I found a way, just update my forked repo). Because I noticed the near commits also failed on Windows.

[szcf-weiya]

Windows failed during the installation of miniconda, so I am guessing (tried to check the documentation https://docs.conda.io/projects/conda/en/latest/user-guide/install/windows.html but failed to find related documentation) whether the error is due to the provided PREFIX folder is not empty since I created the file condarc-julia.yaml in the package building step when (mini)conda was not yet installed.

So the updated version is to write the config file condarc-julia.yaml after installing (mini)conda.

LGTM.

Hm, I tested half a hour ago, and turns out that the underlying issue was already fixed somehow: PyCall, PyPlot, and other dependent packages install just fine on GitHub Actions. The same action failed just two weeks ago with the ResolvePackageNotFound error.

Not sure what changed, and where...

[stevengj]

Probably Conda fixed their packages in the meantime? But I still feel like it is good practice not to upgrade unless the user specifically requests Conda.update().
