How do I install an older kernel in jammy and later Ubuntu?

There were similar questions before, e.g. How do I install an old kernel? but this was in the pre jammy era.

Currently it seems that older packages gets removed from the package list on Canonical servers as they get superseded by newer packages. For example these are search results from jammy and lunar, they only return a couple of versions at best.

For comparison these are results from focal - many vers ...

Is there an image of ubuntu 23.04 with the old ubiquity installer?
za flag

I need to install 23.04 and I'd like to use btrfs with subvolumes and it has to be encrypted. The new installer supports one or the other. I was able to get the setup that I like on the 22.10 installer. I guess I can install 22.10 and then do-release-upgrade to get to 23.04. Someone told me there was an image? If so can not find it for the life of me.

Moved a file with mv but now I can't find it
ru flag

It seems I made a mistake in the command. It still executed a move, but now I can't find the file.

My command was this:

mv /tank/incoming/myfile.mov \(2017\)/ /tank/myfiles/

The command was executed, which took a while, and the feedback was:

mv: cannot stat '(2017)/': No such file or directory

So, where is my file?

Is it still existing? Is there a way to retrieve it?

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.
