Have to manually start gmd3 after installing and uninstalling KDE Plasma
by flag

Some months ago I installed KDE Plasma, didn't like it much and uninstalled it again. Now every time I start my laptop, a black screen comes up and asks for login name and password. After that I have to use systemctl start gdm3 to start the GUI.

How can I make it start automatically as it used to?

Ubuntu 20.04 name user add problem Bug #1927078

A problem occurred while upgrading the version of the Ubuntu system from 18.04 to 20.04.

18.04 user name For example, the user who was using 9128323 cannot log in in 20.04. (GUI only)

9128323 is a company personal number and is created according to company policy.

Due to Bug #1927078, it is impossible to create a number user, but if the badname option is used, I think that new users can use it.

Automatically update dependencies of a metapackage?

I have a metapackage with a few dependencies. When I update the metapackage (apt-get install metapackage), only the metapackage itself is updated and not the corresponding dependencies. I think, this is a reasonable behaviour. However, is there a way to force an update of the dependencies during the "apt-get install"?

I already tried to determine and install the dependencies in the preinst script ...

Does snapd provide a way to fix a broken package?

snap stores all of its packages - including core dependencies such as bare and core as well as every software package as single SquashFS .snap files and then mounts these files (usually in /snap/ directory) in order to access the contents.

On Ubuntu 18.04 (or 20.04, etc) will install recommended packages along with apt-get install, I understand that depended packages should be installed, but why recommended? who decides the recommendation?

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.
