The environment is inconsistent, please check the package plan carefully

Question

I tried to update or install new packages from anaconda and lately, this message has appeared:

The environment is inconsistent, please check the package plan         


        

Answer 1

If the other solutions don't work, reverting the environment can fix this.

Use conda list --revisions, pick a revision number, and use conda install --revision [#] going back step-by-step until everything works again.
