Vault is not installed properly in aws-kms-unseal/terraform-aws

[kawsark]

The userdata script fails to install vault properly. When I ssh into the server and enter commands which vault and which unzip both come back as empty. I do see the vault.zip file downloaded.

As a workaround, modifying the userdata.tpl to have unzip install in a separate line worked:

apt-get install -y unzip 
apt-get install -y libtool libltdl-dev #these installs are unsuccessful

It worked a couple of weeks ago, but I've noticed the same issue before. I thought it was me since it worked inconsistently.

PR 78 fixes this issue.
