I guess that the git in your system is not complete version. Firstly, you can check the git connection using:
git ls-remote "https://oceandata.sci.gsfc.nasa.gov/git/obpgpyutils/" HEAD
if the text like "be40eb6871cf353024c22bdd8e4b014b91bc414a        HEAD" was not shown in terminal, you can try to install a new git following:
$ sudo apt-get install build-essential libcurl4-openssl-dev
$ cd ~
$ wget https://github.com/git/git/archive/v2.11.0.zip -O git_2.11.0.zip
$ unzip git_2.11.0.zip
$ cd git-2.11.0
$ make prefix=/usr/local all && make prefix=/usr/local install
$ export PATH=/usr/local/bin:$PATH
$ which git
/home/$USERNAME/usr/local/bin/git
$ git --version
git version 2.11.0

Then, to check the git connection again.

If the git is okay, please wait for other correct reply.:grin:

Zhigang,
    Thanks for your help. I update GIT, but it seems not to work.
