Conda glibc dependency conflict when installing new enviorment and python version

Question

I have a fresh install of anaconda3 64bit python 3.8 and I am trying to setup an conda env with a different version of python 3.9.7

When I run conda create -n py39 python=3.9.7 anaconda the following error displays:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

  - feature:|@/linux-64::__glibc==2.23=0

Your installed version is: 2.23

I'm a bit confused on how to resolve this since the glibc version 2.23 and 2.23.0 should be the same thing?

Answer 1

It's not about the GLIBC, but rather that Anaconda bundle doesn't have any builds that directly support Python v3.9.7. The newest version Anaconda is built with is v3.9.4. Instead, just specify minor version.

conda create -n py39 python=3.9 anaconda

Or if you want the newer Python, don't include anaconda and specify whatever packages you actually plan to use:

conda create -n py39 python=3.9
