Issue

OS: Ubuntu 20.04

When trying to install Mambaforge 22.11 on a platform not connected to the Internet, the installer tries to update some packages right away and I get the following error:

critical libmamba Download error (6) Couldn't resolve host name [https://conda.anaconda.org/conda-forge/linux-64/ld_impl_linux-64-2.40-h41732ed_0.conda]
    Could not resolve host: conda.anaconda.org

Previous versions of Mambaforge up to 22.09 did not have this problem.

I'm somewhat surprised that this issue didn't occur earlier since the last time we updated micromamba was a few months back #383

It is due to a bug in micromamba: mamba-org/mamba#2187

I think we could accelerate the release of mamba-org/mamba#2265

but the same people that would review a patch proposed for the conda-forge only version would review a patch for the upstream repository.

I can apply the patch to conda-forge once they accept it there.

Does it reproduce with CONDA_OFFLINE=true set?

Given the code path I've identified it is going through, i'm willing to bet it is still an issue.
