"conda update conda" でのエラー
ターミナル上で、conda update conda を打った時に、以下のようなエラーが出てきた（絶対パスのホームディレクトリだけ~で書き換えている）。
$ conda update conda

Solving environment: \ ~/.pyenv/versions/anaconda-4.0.0/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:334: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

ほかの conda の関数（例えば conda install）も調べたが、上のエラーが出て、conda 全体の関数が使えなくなっているようだ。
解決方法
調べてみたが、Conda環境にインタラプションがあるらしいが、気にせず、以下を打てば解決した。
conda config --set ssl_verify no
