Unable to update to 4.2.0 via conda. Latest version 4.1.5 (anaconda.org)?

Problem Description

Until now I could update spyder every time with the command “conda install spyder=x.x.x”. But currently I get the message that 4.1.5 seems to be the latest version and therefore no 4.2.0 is available.

There is the latest version under conda-forge, but I suspect that version 4.2.0 should also be officially available.

I have done the usual troubleshooting (conda update anaconda then conda update spyder), but since the anaconda repro 4.1.5 is mentioned as the current version, I do not suspect a local error.

What steps reproduce the problem?

1. Under win 10, open an Anaconda prompt with admin rights.
2. conda install spyder=4.2.0

What is the expected output? What do you see instead?

Hi @NaderNazemi seems like the issue in your case is an inconsistency being generated do the packages you have in your env. That could be related with #14548 . As suggestion, if you want to check Spyder 4.2.x, is to create a new env and install there Spyder 4.2.0 (running something like this from the Anaconda Prompt should create the new env: conda create -n spyder42 spyder=4.2.0
