New thread on manual update of OCSSW processors

You aren't doing anything silly at all -- if anyone is being silly it is Apple letting people thing they care about security and then shipping python with an obsolete openssl library.1) Does the python script work with python 3.5.2 or does it need 2.7.8?The OCSSW scripts need a python 2.7, but a...

@Swathy -- I just had the same problem so it may have been an internet hiccup.  You can try running update_luts.py manually.   I don't think the install_ocssw.py script does anything more after "Python version acceptable" than run update_luts.py for each requested sensor.

Many open source software providers have moved away from tarballs in favour of direct access to version control repos.  This has important advantages: a) less work for software providers (so they can focus on improving the software), b) users can pull particular versions, and c) lower network c...

NASA is not the only organization moving to https or beefing up crypto protocols for https.  Many sites will be adopting the Mozilla Modern recommendations so if there are problems with NASA now there will be problems with others sites in the future.   It would be helpful to have some...

Connections to oceandata.sci.gsfc.nasa.gov timing out!

Wget 1.13.4 is quite old, so there is a good chance it was built an old version of openssl or gnutls that lacks (Mozilla Modern) crypto support required with many sites that enforce https. The two most common crypto libraries on linux are openssl and gnutls, so it might be useful to check that ciphe...

Installing SeaDAS with sudo or not?

The general principle is that sudo should only be used when absolutely necessary.  SeaDAS works fine when installed without sudo.Are you hoping to share one Seadas 7 install among multiple users?   That is generally not a good idea -- the GUI needs a lot of resources so multiple users...

Have a look at the seadas-7.3.2/config/seadas.config file.  At the bottom you should see something like:# set location of OCSSWROOTseadas.ocssw.root = ${seadas_home}/ocsswseadas.ocssw.location = localThe default install location for install_ocssw.py is $HOME/ocssw, so unless you told it to use ...

How to do atmospheric correction of Landsat 8 correctly through the l2gen GUI?

I'd be worried that Landsat files could be too large to process reliably with 32-bit software, but there are a few VM-specific issues that might cause your problem.   Are your data files stored on the linux virtual disk?   In some VM's disk space set in the VM GUI is not ...
