Hi,

I'm trying the manual install method:

"So, you will need to manually pull down the install_ocssw.py script follow the
manual install/update process (scroll down the page about halfway)"

In the instructions it says:

  $ ./install_ocssw.py --install-dir=$HOME/ocssw --git-branch=<version> --aqua --seawifs
Replace <version> in the --git-branch option with the desired branch. (e.g.--git-branch=v7.2)

I've tried v7.3 and v7.3.2 here as the git=branch. v7.3 works but v7.3.2 does not. If I do v7.3 am I downloading the latest version of SeaDAS or is this older? If older, what do I put here to download the latest version?

Thanks,
Ryan

Yes.  The git repo version only goes to the first "dot",  v7.3 is the latest.

Sean

Ok - great! Thanks for the fast response.

Ryan

I'm have the following problem and can not get the update the ocssw processors or install a clean copy of them.

You have:
./install_ocssw.py -v -i . -g https://oceandata.sci.gsfc.nasa.gov/ocssw/ -b v7.2 -a linux_64 -s --aqua

I think you need the v7.3 branch for the https changes, but you also have a problem with git:

To get more details, try running:
cd /home/woodbri/work/oceandata/run/data/common
git fetch -v
Git uses libcurl, so it is possible that your supporting libraries (libcurl and the TLS library used by libcurl) are too old for NASA's https servers.  See using curl with new https server.

Thank you for your response and suggestions.

I have tried to install v7.2 and v7.3 with the same results.
As for curl and TLS, I have the following:

At work there is a Linux Mint 17.3 system that appears to have working git, but it has been heavily tweaked by someone else so I have no idea how it compares with a "stock" Ubuntu 14.04.  On closer investigation, the report that git was workiong was from Dec. 20th.  The Mint 17.3 system now has the same issue.

@SeanBailey This requirement seems a little severe We are not in a position to upgrade our servers to Ubuntu 16.04 and I have to believe that this impacts a lot of other users also. It looks like this issue is being tracked at https://bugs.launchpad.net/ubuntu/+source/gnutls26/+bug/1444656 but who knows when or if any action will be taken on it since it has been open since 2015-04-15. Is it possible to add any of the chipers supported above to your servers so these older clients can connect?
