But here are some wild and untested guesses what could be done: conda search python This might list the Python versions available. If the desired version does not appear, adding a channel known to host older versions might help, like: conda create -n test python=3.10 -c conda-forge . It might help to update Conda: conda update conda . This should clear the Conda cache, but I don't know what you might lose by doing it: conda clean --all . Check out your conda base and user PATH variables, and prioritize Conda environments over system-wide Python installations. Check your system's networking/firewall configuration doesn't block Conda's access to remote repositories. You could also try to require a more specific version you have, like for example, "python=3.10.4", instead of, "python=3.10".
