The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3B4FE6ACC0B21F32
il flag

I have serious key problems that I am not able to solve. Apt keeps telling me that I do not have a key that I can verify I DO have. The normal answer to this issue is 99% of the time to apt-key add the missing key. However, that is NOT working on this machine and I dont know why. See below as the commands describe the problem better than I can here.

EDIT: DO NOT SUGGEST apt-key add as a fix. T ...

How can I Re-Install 'EFI Partition System' & 'Partition table entries are not in disk order' warning
br flag
nfs

I use Ubuntu 20.04. I have overwritten my EFI partition system. Then I deleted it. After I deleted it, the space became unallocated. (I opened and finalized another question for this issue question link) I have recovered it with Testdisk.

Now, I have formatted the unallocated 513 MB (which was the EFI partition system). I am trying to reinstall what was missing. Unfortunately I couldn't quite catch  ...

Kubuntu 21.04 - how to get hibernate working when it appears disabled from kernel?
cn flag

I'm using Kubuntu 21.04 and trying to hibernate/suspend-to-disk my laptop. I'm not having much luck. The errors I'm getting seem to suggest a deeper issue than all the other Q&As I've seen about this - most other answers seem to suggest echo disk | sudo tee /sys/power/state is the solution, but I can't even get that far. I've tried several things and ultimately ended up at the system sleep sta ...

How can I get my selection of speaker to stick? It keeps resetting
in flag

I have speakers built into one of my two monitors, headphones, and a USB microphone which for some reason is also detected as two different speaker options (there is no output if I select those options). I usually use the HDMI output, sometimes the headphones. But the selected Output Device constantly resets itself to the microphone, so whenever I join an online meeting, or try to play audio, I first ha ...

Is there a way to add additional HW support to the installer/installation process?
sa flag

We've got a lab with a variety of systems used for HW validation. The testing is largely automated including OS install (Windows, Ubuntu 18.04, 20.04, RHEL, etc). All our installs and control are over the network. We also rely on PXE booting so we can reliably transition from one OS to another. The entire process including OS installation is automated/unattended.

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.
