I just updated my VirutalBox to the latest software, and since then I cannot get Ubuntu to load. It black screens on the login screen. I've tried several fixes other forums have mentioned such as the graphics settings, the number of processors, and switching between views, but nothing has worked yet. I know my Ubuntu was slightly out of date, but not sure if that would cause an issue as it worked fine b ...

How can I correct Dependency Evaluation Failure in apt/dpkg installations/upgrades?
us flag

I recently upgraded from Xenial to Fossa, and the entire process appeared to go swimmingly. I have no .list files that reference Xenial on my system, and Fossa appears to be working as intended.

Today, I found that I had an upgradable package, ubuntu-advantage-tools, but it won't install because it depends on distro-info that's not going to be installed. In trying to find out why, it seems that distro ...

Headphone Sound Output Gets Mixed with the Line-Out Output

Problem Summary

When the line-out speaker is selected as the sound output, the sound is fine. Sound comes only from the speakers connected to the line-out port. However, when the headphone is selected as the output device, sound comes out both from the headphone and the speakers.

(EDIT 1) I tested in Windows 10 (using a live USB), and the problem does not occur there. So, this is definitely a soft ...

Why AppArmor logs file read access requests in ASCII expressed as pairs of HEX bytes to the audit.log

I'm running Ubuntu MATE 20.04.2. When I try to launch Cheese from the main menu, a small bar (like a minimised window) appears in the panel at the bottom of the screen, saying "Starting Cheese". After a few seconds it vanishes, and Cheese does not launch.

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.
