Ubuntu 18.04 stuck on boot in tty with no network

I've had a problem with my python3 installation while trying to upgrade it from 3.6 to 3.8 in order to make streamdeck-ui work, and it seems that I broke Ubuntu on my desktop.

On boot, I briefly see the purple screen with loading dots, then it goes to tty and gets stuck there. Network is also unavailable, so I can't use apt in an attempt to clean things up. I don't even have ifconfig. When typing ...

Screen Display settings empty after upgrade to 22.04 with Unity instead of GNOME

For reasons, I installed Unity on top of my 20.10 Ubuntu, so I could use ccsm. When I upgraded to 22.04, the unity-control-center would no longer run or install because it's missing pulseaudio.

will gtk4 apps run on ubuntu20.04

I think Ubuntu22.04 is shipped with gtk4. But I could not find information about compatibility of gtk3/gtk4.

Does a gtk4 app run on a older OS that ships with gtk3? Does a gtk3 app run on Ubuntu22.04 that carries gtk4?

Assuming i am only depending on the system gtk lib.

How to customize GTK file picker display order on KDE?

We use Dolphin normally - but some apps use the GTK picker and forcing the KDE picker doesn't work out well - so instead I'm wondering if it's possible to just change the ordering in the GTK picker?

Dolphin vs GTK Picker

On the left, Dolphin ordering. On the right, the GTK picker spawned by a text editor.

Can we re-order the results so all folders will be grouped at the top? enter image description here

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.
