Dear,
i installed seadas using: ./seadas_7.3.2_linux64_installer.sh
I tried to install the MODIS package with:
./install_ocssw.py --install-dir=./ocssw --aqua --seawifs

It downloaded some packages but at the end i have this error:
fatal: unable to access 'https://oceandata.sci.gsfc.nasa.gov/ocssw/common.git/': gnutls_handshake() failed: Handshake failed
Error - Could not run "cd seadas-7.3.2/ocssw/run/data/common; git fetch -q > /dev/null"

the Issue is in the "git fetch -q > /dev/null" command.

Do yo have any idea of the issue, is the GIT repository still  https://oceandata.sci.gsfc.nasa.gov/ocssw/ ?

Thanks in advance.

You should give some details of the platform in case another reader has already solved your problem.   Some linux distros have git configurations that don't support NASA's https configuration.  For example, if (like many of us), you are using Ubuntu 14.04, a search for "ubuntu git install build-essential" should get you to a post with instructions for installing a current git version.

Dear,

I am using ubuntu 14.04, git version 2.1.4 is it OK?

following your instruction file:https://seadas.gsfc.nasa.gov/downloads/
i used anaconda and finally downloaded the common.bundle file without error  using :
./install_ocssw.py --install-dir=./ocssw --aqua
./install_ocssw.py --install-dir=./ocssw --src

In my directory  $SEADAS/ocssw/ i get these files:
1270770080 avril 28  2016 common.bundle
févr. 13 18:52 run/

Nevertheless no OCSSW_bash.env file as refered into your instruction file:https://seadas.gsfc.nasa.gov/downloads/
export OCSSWROOT=[SeaDAS_install_dir]/ocssw
source $OCSSWROOT/OCSSW_bash.env

And finally i started seadas again and could access any menu in the OCSSW tab. Clicking onto
install oc processors gave me an "ocsww download problem"

Thanks for support

did this command finish without errors?

./install_ocssw.py --install-dir=./ocssw --aqua

I question this because the install script did not cleanup the "common.bundle" file.  I would suggest deleting the whole directory "./ocssw" and trying again.  I think the install script is getting confused by the leftover fragments for the install when you had an old version of git.

You need to install a newer version of git per the search for "ubuntu git install build-essential"

I deleted the ocssw diretory.
my git version is now 2.11

The error is:
cd $SEADAS/ocssw/run/data/common; git fetch
fatal: unable to access 'https://oceandata.sci.gsfc.nasa.gov/ocssw/common.git/': gnutls_handshake() failed: Handshake failed

Thanks for help

The problem is with gnutls.  By default, Git is compiled against that, but that has issues with newer SSL certificates.
you will need a version of Git compiled against the openssl library.  One of our sysadmins described the process:

The "gnutls_handshake() failed: Handshake failed" looks like the old version of git is being used.   You may need adjust the PATH variable to ensure that the new version is used, and you may want to uninstall the old git version.

Your $OCSSWROOT/run/data/common/.git/config seems to be missing the current branch:

[branch "v7.3"]
        remote = origin
        merge = refs/heads/v7.3

You need to add "-b v7.3" to the install_ocssw.py command line.

Dear,

i managed to download the bundle files and install them (i.e. fix the git issue on my Ubuntu).  So now seadas 7.3 and OCSSW are installed.

I setup the following variables as:
export JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre
export PATH=$JAVA_HOME/bin:$PATH
;to get the good version of GIT
export PATH=~/usr/local/bin:$PATH
export SEADAS=xx
export PATH=$SEADAS/bin:$PATH
export OCSSWROOT=$SEADAS/ocssw
source $OCSSWROOT/OCSSW_bash.env

Seadas is launching correctly, nevertheless when i try update (OCSSW/Update OC processors menu) i got this error:

"ocssw installation script failed to download check seadas.ocssw.root in seadas.config".

Is seadas.home of seadas.config different from $SEADAS ?

An idea of the cause of the problem?

Thks

You asked "Is seadas.home of seadas.config different from $SEADAS ?".   The answer is that they should generally be the same, e.g., SEADAS and seadas.home are both set to <SeaDAS_Install_Dir>.  The GUI gets the value for seadas.home from <SeaDAS_Install_Dir>/.install4j/i4jparams.conf.  The message suggests a problem with seadas.ocssw.root, which is set in $SEADAS/config/seadas.config. You can view the GUI's  settings for seadas.home and seadas.ocssw.root (Menu: SeaDAS/About SeaDAS then click on "System Info...").
