problem with conda._vendor.auxlib on "outdated" versions #1832

Closed ReimarBauer closed 1 year ago

ReimarBauer commented 2 years ago

We need a way to block none working installations or warn the users before they try that.

conda create -n mytest mamba python==3.7
conda activate mytest

(mytest) ~$ mamba --version

IIUC this is hard to fix because this old version of Mamba has incorrect Conda compat pinnings (Conda made incompatible changes).
