Problem: minor details missing in digital ocean instructions

[joel-simpson]

I installed Archivematica 1.7 using digital-ocean-install-example.rst

I used Ubuntu 16.04. The instructions still work great, but I noticed a few details that would be helpful to add / correct:

• using Ubuntu 16.04, digital ocean only installs Python 3 by default. I had to add python 2.7 manually first.
• the step about using user.yml wasn't totally clear to me, if nothing else because it was missing the actual ansible command $ ansible-playbook user.yml

I also had real troubles executing this deployment from either my Mac Air latop or iMac desktop. In both cases I had repeated problems with a particular dependency because of TLS errors, due to my Macs using an old version of OpenSSL.

- downloading role 'nodejs', owned by geerlingguy
- downloading role from https://github.com/geerlingguy/ansible-role-nodejs/archive/4.1.1.tar.gz
 [ERROR]: failed to download the file: Failed to validate the SSL certificate for github.com:443. Make sure your managed systems have a valid CA certificate installed. You can use
validate_certs=False if you do not need to confirm the servers identity but this is unsafe and not recommended. Paths checked for this platform: /etc/ssl/certs, /etc/ansible,
/usr/local/etc/openssl. The exception msg was: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590).

 [WARNING]: - geerlingguy.nodejs was NOT installed successfully.

I tried to resolve this by updating OpenSSL but couldn't get it to work. In the end, I found it faster to simply set up another digital ocean droplet from which to run the ansible scripts. (I'm not sure whether any of this last issue is worth noting in the installation instructions, but I note it here just in case anyone else comes across this problem).
