Hi @PravinRanjan10,

Two questions.

Q1. Do you have NON snipped version terminal log? install_ansible.sh shows the ppa repository being used like the bottom.

Q2. Which Ubuntu version are you using? Xenial? or Bionic?

install_ansible.sh executes apt commands like below:

# incorrect version removed, or no ansible found.
echo Installing ansible ${REQUIRED_ANSIBLE_VER} required for ceph-ansible ${CEPH_ANSIBLE_BRANCH} branch.
sudo add-apt-repository -y ppa:ansible/ansible-${REQUIRED_ANSIBLE_VER}
sudo apt-get update
sudo apt-get install -y ansible
sleep 3
sudo add-apt-repository -y -r ppa:ansible/ansible-${REQUIRED_ANSIBLE_VER}

In this case, REQUIRED_ANSIBLE_VER is '2.4', so this is strange.

But, according to the ansible official ppa site information:

https://launchpad.net/~ansible/+archive/ubuntu/ansible-2.4

I guess now ansible 2.5 could be installed in case of Bionic. Please note that install_ansible.sh was tested under Xenial. But, anyway this is an issue to be fixed. You can assign me to this issue.

Terminal log of 'install_ansible.sh'on Ubuntu Xenial in my lab.

Hi, I figured out the root cause and a quick workaround.

This issue comes from the default distro bundled version of ansible. Ubuntu bionic bundles ansible 2.5 series, and we need to specify exact version when we want to use a downgraded version like below.

ubuntu@ubuntu203:~/opensds-installer/ansible$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.1 LTS
Release:        18.04
Codename:       bionic

ubuntu@ubuntu203:~/opensds-installer/ansible$ sudo add-apt-repository -y ppa:ansible/ansible-2.4
  (snip)
ubuntu@ubuntu203:~/opensds-installer/ansible$ sudo apt-get -y install ansible=2.4.6.0-1ppa~bionic

ansible 2.4.6.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/ubuntu/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.17 (default, Nov  7 2019, 10:07:09) [GCC 7.4.0]
ubuntu@ubuntu203:~/opensds-installer/ansible$

I don't think this is the reason why you got #326 , but anyway I will update 'install_ansible.sh' soon.

Here is a (manual) workaround procedure.

1. Identify your preferred ansible verson.
   • In your case, it should be 2.4
2. Add appropriate ppa repository.
   • `sudo add-apt-repository -y ppa:ansible/ansible-2.4
3. run apt-get update
4. check the package version
   • apt-cache showpkg ansible | grep 2.4
   • Now the up-to-date ppa version of 2.4 series seems to be '2.4.6.0-1ppa~bionic'
5. Install the exact version ansible by specifying package version above.
   • sudo apt-get -y install ansible=2.4.6.0-1ppa~bionic
6. Check version of the installed ansible
   • ansible --version

Sorry for my (very) late action. I created a PR for this issue.
