Run apt upgrade and apt autoremove?

[borellim]

This would:

• keep all packages up to date (upgrade)
• save disk space (autoremove)

Questions:

• any disadvantages?
• do we already do it anywhere?

This is also for the Cloud edition.

Both of these commands are already run as part of the simulationbase role.

• apt upgrade is already run here
  https://github.com/marvel-nccr/ansible-role-simulationbase/blob/68b025c9bfcfe50b046aca06f50796cc212960e1/tasks/package_managers.yml#L5
• apt autoremove (as well as other "cleaning" commands) are run when
  https://github.com/marvel-nccr/ansible-role-simulationbase/blob/master/handlers/main.yml

Note that both require guards since they aren't idempotent (guard for apt upgrade: 1 day cache; guard for autoremove: only run on demand)

Ok, thanks a lot. I'll look into these.

EDIT: I'm not closing the issue because several packages are out of date even immediately after deployment. In fact, I suspect the correct form of the first task you linked would be:

  apt:
    name: "*"
    state: latest
    cache_valid_time: 86400  # One day

MEMO: upgrading the kernel breaks the VirtualBox guest additions, unless kernel headers are also installed.
To install kernel headers, install package linux-headers-generic: the latest version will be installed.
