Streisand: Streisand fails on purging unneeded services.

[btabibian]

I have been trying to install streisand on AWS services but received the following error. I have been able to skip this step without further problems by changing main.yml file.

I believe this is due to a change in removing "snapd".

Just so everyone else know it, I managed to get server up and running by updating playbooks/roles/common/tasks/main.yml:

- name: Purge unneeded services
  apt:
    package: "{{ streisand_unneeded_packages }}"
    state: "absent"
    purge: no
    autoremove: no

nice workaround, Thanks.

[the-darkvoid]

A less impactful edit can be done on playbooks/roles/common/vars/main.yml.

Update the streisand_unneeded_packages variable here to exclude snapd, as per @btabibian's comment.

# Services that are running by default but not needed by Streisand
streisand_unneeded_packages:
   - lxd
#  - snapd

[Keridoo]

This works but I run into further problems down the Ansible pipeline.
