[FIXED] Trouble updating to Spyder 4.0.0

Issue

I am under Windows 10, 64 bits.

I tried several time to update Spyder 4.0.0 with both the Anaconda Prompt and the Anaconda Navigator. It failed. I uninstalled Anaconda and reinstalled it.

Then I ran the Anaconda Prompt as an Administrator and executed :

conda update spyder

The version of Spyder was 3.3.6. I tried this command :

conda install spyder=4.0.0

The prompt returned :

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

When launching the Anaconda Navigator, the Spyder version was still on 3.3.6.

What am I missing to benefit the last version of Spyder ?

EDIT 1:

When I try to use the Anaconda Navigator, it says :

spyder 4.0.0 cannot be installed on this environment

And it proposes other environments to install but I want Spyder to be updated, not installed somewhere else.

EDIT 2: I successfuly change conda to 4.6, but I get these two errors :

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\brichard\\AppData\\Local\\Continuum\\anaconda3\\Menu\\spyder_shortcut.jsodone

and :

CondaError: Cannot link a source that does not exist. C:\Users\brichard\AppData\Local\Continuum\anaconda3\Scripts\conda.exe 
Running `conda clean --packages` may resolve your problem.

The conda clean --packages command does not help since the same errors are raised after it is executed.

Solution

(Spyder maintainer here) Other users have reported that you need to run

conda update anaconda

and then

conda install spyder=4

to successfully update to version 4.
