The log shows "Caused by: java.awt.HeadlessException".  In plain language, this says Java didn't find keyboard, mouse, or display so is running in "headless" mode.

I have SeaDAS 7.4 on Linux Mint 18.1 (based on Ubuntu 16.04).  After running update_luts.py I also have the new $OCVARROOT/viirsn/cal/OPER/*_LUT_v2.0.0.2_obpg.nc files but ocssw/run/data/viirsn/instrument_defaults.par still has *_LUT_v1.1.0.1_obpg.nc.

The "quick fix" get around an incomplete or broken installation is to remove the broken software and install a "known working" configuration (Anaconda python 2.7, which includes curl or macports' python 2.7 with git, wget, and curl).   The "--no-check-certifica...

For https URL's, wget needs an SSL/TLS library, usually openssl, and certificates.  I use Macports's wget on darwin 15.6.0, linked to Macports' openssl.  The certifcates are in /opt/local/etc/openssl and come from the curl-ca-bundle package:Description:      ...

You don't mention the python version.   Apple's python uses an old SSL library that doesn't support NASA's https configuration, so you will need a more up-to-date Python 2.7.   If you did install a newer Python, you may need to adjust your PATH variable to ensure ...

You are making things too complicated.  Assuming you have the  Required software,  in a terminal, just run:wget https://oceandata.sci.gsfc.nasa.gov/SeaDAS/installer/7.3.2/seadas_7.3.2_linux64_installer.sh and you should see something like:--2017-03-03 12:04:59--  https://oceandat...

Last year you found processing images one at a time was slow.   At that time I suggested that you might find a terminal and shell scripts helpful.  Now it turns out that the terminal is not avoidable if you need to update the OCSSW processing system before the new GUI appears.  I...

The default location of ocssw for the GUI is <seadas_install_dir>/ocssw while for the command-line installer it is $HOME/ocssw.   You can change the location in the GUI by editing <seadas_install_dir/config/seadas.config.   For example, to use $HOME/ocssw the last few lines of se...

You mentioned: "(export OCSSWROOT=$HOME/seadas-7.3.2/ocssw and $ .ocssw/OCSSW_bash.env )".   It isn't clear that the second command is equivalent to "source $OCSSWROOT/OCSSW_bash.env" or ". $OCSSWROOT/OCSSW_bash.env".   If you have more than one ...

You are using /usr/bin/git which is probably still Ubuntu's old version.   What is echo $PATH?   The directory where the new git resides should come before/usr/bin.   Another option is to uninstall the Ubuntu version using your package manager (if this fails because...
