I would like to fully upgrade this system to the latest LTS. But first I would like to feel the current 16.04.7 LTS is clean. I tried to install Owncloud years ago with limited success and then uninstalled it. Unfortunately, my system thinks it's still installed and has issues.

Currently sudo apt-get update yields the following:

Ubuntu 21.10 on Dell XPS 17 9700 WiFi Killer AX500s DBS stopped working in kernel 5.13.0-21-generic
cn flag

This is essentially the same question as that from axtimwalde.
I bought the XPS 17 9700 in April and after a lot of struggling got it to dual boot Windows 10 and Ubuntu 21.04 (having failed with 20.04 LTS).
Then a week or two ago, I ran apt upgrade and the wifi adaptor disappeared in Ubuntu. It also went in Windows 10, so I assumed a hardware failure and contacted Dell hardware support. After some tests ...

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.
