I understand that with the release of Ubuntu 22.04.2 LTS, support has been provided for the 5.19 kernel and HWE packages.

However, upon checking the Linux long-term kernel versions on the following site, it appears that 5.19 is not a long-term kernel, and version 5.19.17 reached its EOL on October 24, 2022.

Consecutive networkd-dispatcher error messages for virtual Docker interfaces

My question is much like the issue described here, except I'm using an LXC of Ubuntu 23.04. In that answer, it was marked as solved because I guess the networkd-dispatcher service was patched. However, I am getting the same errors in 23.04, and the only way I can stop them is by restarting the service. Here is the journal output of the networkd-dispatcher service showing the error in question:

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.
