Ubuntu Pro License for VMs

I'm a little bit at a loss understanding how Ubuntu Pro license works for Vms. It says "all the VMs running on these hosts", then listing a lot of hosts (from qemu/KVM to EXSi to Hyper-V to others), and "every node in the cluster must be subscribed".

How can I subscribe a EXSi node/host? Is there like a dedicated client? And what about Proxmox (qemu/KVM based)? Should I just subscribe the VMs and ...

MOTD: '444 updates can be applied immediately'. `apt list --upgradable` lists just 4!

I have a Ubuntu 18.04.6 LTS machine that says to me, after logging in:

444 updates can be applied immediately.

To see these additional updates run: apt list --upgradable

But when I use apt list --upgradable, as suggested, it lists just 4 available updates.

  • Why is the machine lying to me?

I don't remember doing anything that could possibly justify this passive-agressive behaviour towards me.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
