Error - Could not install luts for aqua
Can you help me?
Thank's

"Exception: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726)" may indicate a network glitch or a configuration issue on your system.   I often have to retry the install several times to get the aqua-luts to install.  You should check that you can download the LUTS manually from a browser (see previous posts on problems with update_luts.py). If the install fails after several attempts spread over time, you should provide your OS version and the source of your Python software.

Thank you for answering George.
I have tried to install several times, through SeaDAS and the terminal, the error message is the same. This problem started when I installed version 7.4, the problem was solved only when I completely reinstalled my OS. I had already tried some forum solutions but it did not work. My system is MacOS High Sierra and I have Python 2.7 and 3.6 installed and updated, downloaded direct from www.python.org. I'm still trying.
If you have any more suggestions I will be very grateful.
Flavio

Flavio,

We do not (yet) have a system with High Sierra to test, but my guess is you are suffering from the same python/SSL issues from previous versions.  A solution that may work for you is to install another version of python (e.g. Anaconda), as was suggested in this post: https://oceancolor.gsfc.nasa.gov/forum/oceancolor/topic_show.pl?pid=32217

Hello Flavio,
I am running macOS High Sierra with Python 2.7 and 3.6, and experienced the same error. I ran the following two commands (without the quotes) in Terminal:

"/Applications/Python\ 3.6/Install\ Certificates.command"
"/Applications/Python\ 2.7/Install\ Certificates.command"

This seems to have fixed the issue for me.

Thank you George, Sean and Lauren. It was enough to install the miniconda to work.
However, I would like to register, as information: In version 7.4, when this problem started, I installed and reinstalled python, including the anaconda (graphical interface and terminal) in different sequences, but it did not solve. The installation of OCSSW returned to work when I formatted my MacBook and reinstalled my MacOS. In version 7.5 when the problem reappeared, I did not think of the anaconda because I had tried before and it did not work and I thought about the possibility of conflict between installers.
Sorry for the delay in answering because I was doing some tests. I installed Anaconda 2 and 3. When I installed Ancaconda 3 the problem returned. I reinstalled Anaconda 2 and 3 and OCSSW install worked.
The difference between the situation when the problem came later and now, is that this time I installed the anaconda in the root directory.
Again thank you very much to all.
Regards,
Flavio.
