I have tried, unsuccessfully, to get various AI models to create a script that will curl or wget the latest Ubuntu LTS desktop torrent, even should that LTS version update in the future (beyond 24.01.1 LTS). The purpose is that I would like to seed whatever the latest LTS torrent is and I don't want to have to keep checking the Ubuntu page for updates, I want it automatic. I know that LTS is slow to change versions but I am annoyed that AI can't just write a decent script for this.

I also have downloaded rtorrent as a command line and will deal with how to make sure the latest LTS is used, as opposed to the prior one, with a different script later, but that's not what I'm trying to now.

I am not asking for a human to create this script for me. I am asking why AI models keep getting this so wrong. I've tried ChatGPT 4o, I've tried DeepSeek, I've tried other localized models, Reasoning Models. They all fail. And when I execute their code, and I get errors and show it to the models, they still fail, many times in a row. I want to ask Lemmy if getting an answer is theoretically possible with the right prompt or if AI just sucks at coding.

This shouldn't be too hard to do. At https://www.releases.ubuntu.com, they list the releases. When curling the webpage, there's a list of the releases with version numbers some with LTS. New versions are always larger numbers. At https://ubuntu.com/download/alternative-downloads, they list the torrents. Also, all release torrents for desktop are in the format https://www.releases.ubuntu.com/XX.XX/desktop.torrent. I've tried to teach these models this shit and to just create a script for me, holy shit it's been annoying. The models are incredibly stupid with scripting.

I'm not a computer programmer or developer and am picking up more coding here and there just because I want to do certain things in linux. But I just don't understand why this is so difficult.

So my question is, is there ANY prompt for ANY model that will output successful code for this seemingly easy task, or is AI still too stupid to do this?

Why the hell would you ask an AI model to write the script for you? It's a one-liner, took me just a minute to write. Even if you know very little of Bash I can't imagine it would take more than a few minutes of research to figure it out.

curl $(curl https://ubuntu.com/download/alternative-downloads | grep -o "https.*desktop.*torrent" | tail -1) -o ubuntu-latest.torrent

AI is mediocre at best when it comes to writing code, and if you don't have the skill to troubleshoot its garbage outputs you shouldn't be using it at all.

Great solution (esp the corrected one further down). I can relate to OP in the sense that if I studied programming, I might be able to whip something like this up, but so far I haven't been disciplined enough to learn and practice programming consistently.

It's also interesting, this new AI variation of Cunningham's Law, wherein posting an incorrect solution on a discussion board will yield way more attention and correct answers than asking a question. It's interesting to wonder why that is.

I mean, I think that that's not a hard question to answer. If AI can do something, then anyone who can use human language can also do it.

That's true as of 2025, and a solid issue. I don't think that a purely-LLM based solution is going to be the final solution.

I do think that AI will ultimately get there, though.

Thank you! There are two different kinds of people in the world. There are those great at coding and those great at watching netflix and doing whip-its.

edit: actually this torrent downloads ubuntu-22.04.5-desktop-amd64.iso, which isn't the latest LTS version (which is 24.01.1). It's probably good enough, but part of the challenge in this was to always torrent the latest one.

does anyone know why ubuntu-latest.torrent would try to download 22 instead of 24 LTS?

[–] [email protected] 12 points 19 hours ago (2 children)

My bad, that's what happens when you write a script in a minute. It turns out the latest LTS version is actually the second one listed, not the last. This one should actually fetch the latest version:

curl $(curl https://ubuntu.com/download/alternative-downloads | grep -o "https.*desktop.*torrent" | sed "2q;d") -o ubuntu-latest.torrent

Hooray!

look everyone, i figured it out using various methods, i'm a programmer now

[–] [email protected] 2 points 16 hours ago (2 children)

I’m so confused. Why are you using sed and grep? Can’t you use sed and/or awk to write a regular expression?

[–] [email protected] 4 points 16 hours ago* (last edited 16 hours ago)

I'm not the author, but I regularly use grep and sed in conjunction for things that sed or awk can theoretically do alone via multiple commands. I think that that's pretty common -- grep is used as the search tool, sed as the replacement tool, and you stick 'em together at the shell level. Memory usage isn't very significant for something like this.

[–] [email protected] 2 points 14 hours ago

grep finds the URLs for the desktop torrent files, sed selects the second one. There's probably a more elegant way to do it but for a quick script it's fine.

ubuntu-latest.torrent (what's written after -o) is the output name. You should be very careful with executing commands that you don't fully understand. Might save you a lot of trouble in the future.

[–] [email protected] 8 points 19 hours ago (1 children)

You can be good at anything if you just put in some effort. The mindset that since you're not good at programming you can never be is stupid.

[–] secretlyaddictedtolinux 2 points 19 hours ago* (last edited 19 hours ago)

I don't know if that's actually true. If I'm 5'2" and uncoordinated will I ever become a professional basketball player? I try to be honest with myself about my strengths and weaknesses. For me, just stopping windows was the victory.

It took me more time to read this thread than it did for me to learn the basics of Bash scripting.

Do like we did back in the day, RTFM

Just write it yourself 🤦‍♂️

[–] [email protected] 10 points 20 hours ago

Probably a stupid comment, but still: if you're a coder, you might be quicker just writing such a script yourself. Just fetch the links, slice them up, sort them by version and wget the one with the highest number.

If you're not a coder, maybe someone here can help out?

AI isn't stupid because it doesn't possess any intelligence to begin with, the term "AI" is just a marketing misnomer.

Language Models are essentially really advanced Markov Chain generators. Once you understand that, you'll realize why your question is like "I keep asking these water mills to make me a cup of coffee, but they all taste like dirt": wrong tool for the job, it just happens to be tangentially related.

You're also asking if there's a way to precisely word a request so that the computer will do what you want it to do. Luckily for you, there is! It's a trick that's been around for ~60 years and it's called "programming languages"

AI certainly can do it. But here's the thing with generative AI: the answer is only as good as the question you ask. If you don't know exactly what to ask for and which details are important, the AI doesn't know what you meant to ask and can't infer that. AI usually does not pick up implied context that an experienced person would. A person would be able to make an educated guess about what you actually meant and answer that question.

As someone with 20 years of programming experience, I would recommend against using AI to learn to program. You're asking something that doesn't actually know how to program to show you how to do it. From my experience with coworkers using AI, it doesn't improve their work; it simply accelerates the rate at which they can produce low quality work.

Once you're more skilled than the AI, you can use it to speed up menial tasks, like generating boilerplate and stubbing things out. It absolutely will be wrong in some ways, and you need to be able to tell when it's wrong and know how to fix it.

@[email protected] I bet there is a RSS feed for Ubuntu releases. Instead of using AI to get the link you would need to read consume the feed.

In my experience, Chat GPT is much better at the general programming patterns and concepts than specific API implementations. Especially less commonly used ones, where it often gives a solution that only looks reasonable but uses the totally wrong methods. I guess it's similar with scraping the HTML of the Ubuntu releases page to get the latest torrent. It doesn't know the exact HTML layout, so it guesses what is a likely one, even though it is wrong.

The AI will provide methods you could try, but ultimately a human will need to review and edit the code.

You are a powerful terminal assistant. You will answer in the most helpful possible way and provide the user with Linux bash commands to accomplish their tasks. Use Google and internet search to fetch all necessary information. Always format your answer in markdown format.

User question: How do I download the latest Ubuntu ISO torrent? Make sure it's the latest version from ubuntu.com Make sure to also include the curl or wget command to download the torrent file itself.
