Run `apt upgrade` and `apt autoremove`? #127

Open borellim opened 4 years ago

borellim commented 4 years ago

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EDIT: I'm not closing the issue because several packages are out of date even immediately after deployment.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.
