Provision fails: "No package matching "python-software-properties"

This is weird: on a brand new VPS running Ubuntu 16.04.2 LTS, using latest trellis (0.9.9) I cannot seem to provision the server.

The message:


failed: [next.domain.com] (item=[u'python-software-properties', u'python-pycurl', u'build-essential', u'python-mysqldb', u'curl', u'git-core', u'dbus', u'libnss-myhostname']) => {"failed": true, "item": ["python-software-properties", "python-pycurl", "build-essential", "python-mysqldb", "curl", "git-core", "dbus", "libnss-myhostname"]}

I’ve tried installing the missing package manually but it refuses, saying:


Package python-software-properties is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  software-properties-common

E: Package 'python-software-properties' has no installation candidate

So I installed the suggested package instead, no go. Same error message. What is going on?

The full log:

$ ansible-playbook server.yml -e env=production

I managed to solve this thanks to this answer on SO.

Basically:

Log via SSH to the server
Rebuild the Sources list using this (awesome) tool.
Then launch the curl that it generates
apt-get update
apt-get install python-software-properties
retry provisioning.

I was testing this out on 18.04 bionic by doing a switcheroo for this:

github.com

roots/trellis/blob/457476347b057731d649c73f5ee8bcec32bc93ad/roles/common/defaults/main.yml#L24


    'env_pair': {{ env_pair }},
    'site_keys': {{
                   (vars[env_pair[0] + '_sites'].wordpress_sites | default({})).keys() | intersect(
                   (vars[env_pair[1] + '_sites'].wordpress_sites | default({})).keys())
                 }}
  },
{% endfor %}
]"


apt_packages_default:
python-software-properties: "{{ apt_package_state }}"
python-pycurl: "{{ apt_package_state }}"
build-essential: "{{ apt_package_state }}"
python-mysqldb: "{{ apt_package_state }}"
curl: "{{ apt_package_state }}"
git: "{{ apt_package_state }}"
dbus: "{{ apt_package_state }}"
libnss-myhostname: "{{ apt_package_state }}"


apt_packages_custom: {}
apt_packages: "{{ apt_packages_default | combine(apt_packages_custom) }}"

Cut python-software-properties
Paste software-properties-common

TOTAL FAIL!!

Reverted to an AWS 16 instead
