Installation on ubuntu 18.04 fails about ansible-docker HOT 10 CLOSED

Ran into the same issue on a stock ubuntu 18.04 (which doesn't add universe per default).
Solved it by adding

- name: Add universe repository for bionic
  apt_repository: 
    repo: deb http://archive.ubuntu.com/ubuntu bionic universe
    state: present
  when: ansible_distribution_release == 'bionic'

in pre_tasks of my playbook

Hi,

That's interesting. It passes the tests for Ubuntu 18.04 on https://travis-ci.org/nickjj/ansible-docker/jobs/446816674 and I've installed this role a lot of times on DigitalOcean using 18.04.

Also, it looks like gnupg2 exists on https://packages.ubuntu.com/bionic/gnupg2.

Have you ran apt-get update on your host at least once? This should be a part of any Ansible bootstrap strategy which is why this role doesn't run apt-get update on its own.

That did the trick, thanks a lot and sorry for bothering!

I'm having the same problem, I am not sure why gnupg2 is not present in the current repolist (even after apt-get update -y)

What I have did before running the play:

• install the latest Ubuntu18.04 server on 2 virtualbox VMs.
• install kubeadm, kubectl and kubelet ( like here: kubernetes.io )

If you need anything else from me to help you debug this problem I'll try and provide info.
I'll clone this machine to ensure the current configuration is not lost.

@Zauxst I think I narrowed down the problem.

If you run cat /etc/apt/sources.list do all of your URLs end with main?

If so, edit that file so the first one ends with main universe and then run sudo apt-get update.

I think the problem is your installation of Ubuntu didn't configure the apt source lists to allow community packages to be installed and gnupg2 and others fall into that category.

Doing that really isn't a responsibility of this role. It should be done when you bootstrap your server or configure apt IMO.

from ansible-docker.

@nickjj yes indeed, adding universe solved the problem. Thanks a lot for taking the time.

I'm not going to go into a philosophical debate about it, this is my 2cent of this topic:
If a role requires a package to finish running, that is not in main (in our case it was Universe) it should ensure the package is ready to be downloaded, or at least mention it in the script requirements.

Besides... Ubuntu=16.04 and 18.04 doesn't require gnupg2 according to the official installation. Only the Debian install does.

before:

cat /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu bionic main
deb http://archive.ubuntu.com/ubuntu bionic-security main
deb http://archive.ubuntu.com/ubuntu bionic-updates main

after gnupg2 was found.

Yep, but in this case, adding it for Ubuntu doesn't do any harm and while it's possible to split it up, it drastically complicates the role (both at configuration and implementation levels).

My philosophy is determining whether or not to use universe, backports, etc. is a system level decision that should be configured once with an apt or similar role.

Having this role start to modify apt source lists to make a system level decision as important as that one doesn't seem reasonable IMO.

But, having it as part of the documentation makes sense. It's just most cloud providers have universe enabled by default, so I didn't even think to add that. I only figured it out because I ended up setting up a stock Ubuntu server (which only allows main) recently and ran into the problem first hand.

Hi nick, thanks for sharing the role. It has been quite useful. I also encountered the issue on a newly provisioned aws bionic server and running the apt-update step fixed the issue. will add the it as the first step in all my future ansible playbook.
thanks.

Hi, yeah it's expected you run an apt-get update when bootstrapping a server. Otherwise you wind up in a situation explained in my previous reply.

from ansible-docker.

Yep, that's standard. You may want to also consider offloading that task to a designated apt / bootstrap role since it's very much system dependent.
