[ansible] Central Server script doesn't work on Ubuntu 18.04 Minimal

[nanndoj]

The ansible script for setting up the central server is failing when installing on a Minimal version of Ubuntu 18.04 (ubuntu-minimal-1804-bionic). This is because the locales package is not installed by default in this image.

One possible solution is to ensure that the locales is installed on the xroad-base script as described in https://github.com/nordic-institute/X-Road/blob/develop/doc/Manuals/ig-ss_x-road_v6_security_server_installation_guide.md#24-preparing-os

Steps to reproduce

Run the playbook xroad_init.yml on a minimal version of Ubuntu 18.04 bionic.

Expected results

The script should run without any problems.

Actual results

The script fails with the following error

failed: [xx.xx.xx.xxx] (item=en_US.UTF-8) => {"ansible_loop_var": "item", "changed": false, "item": "en_US.UTF-8", "msg": "/etc/locale.gen and /var/lib/locales/supported.d/local are missing. Is the package \"locales\" installed?"}

Your open PR (#187) seems to contain a fix to the problem. There's an issue about evaluating and approving the PR in our backlog so it has not been forgotten.

https://jira.niis.org/browse/XRDDEV-712

As a workaround it's also possible to install the missing package manually before running the Ansible script.
