Cant install git and other packages

[Tobias-Fischer-Official]

When i try to run one of my roles (it has gantsign.oh-my-zsh as dependency) with this container, i get the following error:

TASK [gantsign.oh-my-zsh : install dependencies] *******************************
failed: [localhost] (item=git) => {"changed": false, "item": "git", "msg": "No package matching 'git' is available"}
failed: [localhost] (item=zsh) => {"changed": false, "item": "zsh", "msg": "No package matching 'zsh' is available"}

The code of the executed task is

---
- name: install dependencies
  become: yes
  package:
    name: '{{ item }}'
    state: present
  with_items:
    - git
    - zsh

In your container for ubuntu1404 and in my local xenial vagrant-machine it is working without problems.
Probably im stupid, and the error is on my end, but im kinda out of ideas what to try next to solve the problem. Any help is greatly appreciated.

i just figured out that there is an apt update task missing before the quoted task...
so this is not an issue with the docker image, im sorry for any inconvieniences i caused, this ticket can be closed or deleted.
