How to update miniconda and Spyder 4.2.1

Question

When I opened Spyder, I saw a message of

Spyder 4.2.1 is available! Instead, run the following commands in a terminal 
conda update anaconda
conda install spyder=4.2.1"

I installed miniconda before, so I opened anaconda prompt, then type in

conda update anaconda

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Users\yongn\miniconda3
  package name: anaconda

then I switched to

conda update miniconda

and I got same error:

PackageNotInstalledError: Package is not installed in prefix.
  prefix: C:\Users\yongn\miniconda3
  package name: miniconda

any suggestion on how to update miniconda?

Answer 1

$ conda update conda

conda is the package manager. Anaconda is the big enchilada with >100 packages included.
