scl python27でcertbot-autoがpython 2.6 DeprecationWarning を出してくる

# scl enable python27 "/opt/certbot/certbot-auto renew --no
-self-upgrade"                                                                
/opt/eff.org/certbot/venv/lib/python2.6/site-packages/cryptography/__init__.py:26: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of cryptography will drop support for Python 2.6
  DeprecationWarning

# scl enable python27 "python -V"                             
Python 2.7.13 

# scl enable python27 "which python"

• certbot-auto初回起動時のbootstrapがpython26で動いていた？
• /opt/eff.org を一度消すと再度bootstrapが走るのでパッケージを入れ直す
  • 他にbootstrapを起動する方法があればそちらでもOK

# sudo rm -rf /opt/eff.org
# scl enable python27 "/opt/certbot/certbot-auto renew --no-self-upgrade"
