[conda] CondaHTTPError: HTTP 403 SSL IS REQUIRED

[Saeedeh Lohrasbi]

I am trying to update my Anaconda but I get this error:

Solving environment: failed

CondaHTTPError: HTTP 403 SSL IS REQUIRED for url
<http://pypi.python.org/simple/noarch/repodata.json>
Elapsed: 00:00.021272

The remote server could not find the noarch directory for the
requested channel with url: http://pypi.python.org/simple

As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json`
is
empty. please request that the channel administrator create
`noarch/repodata.json` and associated `noarch/repodata.json.bz2` files.
$ mkdir noarch
$ echo '{}' > noarch/repodata.json
$ bzip2 -k noarch/repodata.json

You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current
state.
Further configuration help can be found at
<https://conda.io/docs/config.html>.


Does anybody have any idea about it?
