Can not install any package with conda - CondaHTTPError: HTTP 400 BAD REQUEST

[er...@sqreamtech.com]

hi,

I do not success to install any package with  conda - all get http 400 error.

when try to access directly the url - then it not a problem.

example:

CondaHTTPError: HTTP 400 BAD REQUEST for url <https://conda.anaconda.org/conda-forge/linux-64/certifi-2017.11.5-py27_0.tar.bz2>

Elapsed: 00:00.706761

An HTTP error occurred when trying to retrieve this URL.

HTTP errors are often intermittent, and a simple retry will get you on your way.

CondaHTTPError: HTTP 400 BAD REQUEST for url <https://conda.anaconda.org/conda-forge/linux-64/ca-certificates-2017.11.5-0.tar.bz2>
