Cannot find device "can0" with Ubuntu-Server 20.04

my question is about using the SPI interface to do some things with CAN. On my Raspberry with the Raspberry OS everything worked fine.

Since I want to use the CAN data with ROS, I decided to install Ubuntu Server 20.04 on it. In doing so, I ran into a problem (Cannot find device "can").

These are my configurations:

Gamecube Controller Adapter not working
co flag

I followed this guide for getting my Gamecube controller/Mayflash adapter to work with Ubuntu (I'm on 22.04). The program built correctly, but the adapter is not being detected in any programs in either PC or Switch/Wii U mode. However, it does appear in the hardware list and works on gamepad-tester in PC mode. Has anyone else had trouble with this program? Does anyone have a solution?

How to use MiniNova USB MIDI keyboard?

The Novation MiniNova USB MIDI keyboard doesn't work on my setup. I'm running Ubuntu 20.04

There are halfway solutions floating on the internet, and perhaps the best suggestion is another query on AskUbuntu (2019), which suggests editing the kernel to get the MiniNova to work properly.

I am open to suggestions. I contacted the keyboard manufacturer but was unable to find a resolution.

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.
