How often do you update Proxmox?

[mtzdb]

Hello,
I installed Proxmox three months ago, and I have a question about how often I should run commands like `apt-get update`.

On Proxmox, according to forum members' rules, I installed only the default package plus Tailscale for tunneling (https://share.cleanshot.com/WV7wqFVR).

I want Ubuntu to install security updates automatically. Is this strategy also recommended for Proxmox?
Which approach for this problem is the best?

I've configured the Postfix email system on all my nodes, and now I automagically receive emails when new updates are available. Proxmox apparently runs apt-get update for us, so there is no need to worry about how often to run it.

You may find inspiration how to configure Postfix in these threads:

Some updates require that the server gets restarted, i.e. when updating the kernel, and doing that automatically seems dangerous to me.

Since I'm a lucky guy who has an HA-cluster I just bulk migrate all VMs to another node before doing the upgrades.
