curl command never succeed in first try.always need to run it twice

[chrisrana]

I am doing installtion of cf_nise_installer
export NISE_IP_ADDRESS=128.100.45.67 public ip

I ran all the command from root user by sudo su

When I ran following command first time ,it finished in 5 minutes and didn't created cf_nise_installer folder

bash < <(curl -s -k -B https://raw.githubusercontent.com/yudai/cf_nise_installer/${INSTALLER_BRANCH:-master}/scripts/bootstrap.sh)

last line is
Setting up git-core (1:1.9.1-1ubuntu0.3) ...

script ends after this line.

Then I ran same command second time this time installation succeed and i can see cf_nise_installer folder.
This problem I faced so many time on ubuntu 14.04

I again created fresh Ubuntu 14.04 VM and did some configuration as below and ran the command but no luck in first attempt.

export INSTALLER_URL=https://github.com/yudai/cf_nise_installer.git
export INSTALLER_BRANCH=master
export NISE_IP_ADDRESS=128.107.36.242

and ran the command
bash < <(curl -s -k -B https://raw.githubusercontent.com/yudai/cf_nise_installer/${INSTALLER_BRANCH:-master}/scripts/bootstrap.sh)

last line is
Setting up git-core (1:1.9.1-1ubuntu0.3) ...

It seems it is exiting after sudo apt-get install -y git-core

Am I missing something here ?
