Apt update

To upgrade all packages through apt, the following playbook can be used:

- name: Update apt software
  hosts: computers
  gather_facts: no
  
  roles:

  - role: ufrmath.computer_labs.wol

  - role: ufrmath.computer_labs.update_apt
    dist_upgrade: yes
    delegate_build_to: tp-server

which uses the role ufrmath.computer_labs.update_apt.

This role first execute the role ufrmath.computer_labs.patch_systemd to ensure that the patched version libpam-systemd-patch of libpam-systemd is available in the custom repository (otherwise systemd might not be upgraded, or some packages might get automatically removed if dist-upgrade is used).

The manual command are simply:

sudo apt update

followed by:

sudo apt upgrade

or

sudo apt dist-upgrade

if the option dist-upgrade is yes.
