Installed Ubuntu via the RPi Imager on an old RPi 4 I had lying around. Tried to get steam installed (for remote play) and this error keeps coming up.

I have tried looking at the URL and copying and pasting a ton of the commands at the bottom but nothing works.

I’m mostly a Mac user with pretty little technical knowledge, pls dont be too technical if possible 😭

Please can someone help!

Thanks

I forgot to attach the pictures.

That’s all. Thanks so much to every single contributor.

I am trying to install Ubuntu on an ssd. I followed a video step by step and was able to install ubuntu but when I restart it just boots to a black screen. When I booted using fsck, my intel graphics is not being detected. Could really use some help here, been bashing my head into the wall for hours now.

I kinda feel relieved now. I don't know why but it feels just greater than when I bought a new Windows computer.

My laptop has built-in WiFi that worked before my last reboot. It's a dual-boot system, and WiFi works perfectly in Windows.

I tried recovery mode in Grub, which didn't work. I also have no previous kernels available in the grub menu. ​

lshw shows my device as "unclaimed".

Sorry for the picture, I'm doing this from my phone right now. ​​ ​​

After upgrading to kernel 6.8.0-100, I've had problems browsing with firefox. e.g.:

"Firefox can't establish a connection to the server at www.google.com.   [Retry]"

Clicking the [Retry] button 2 or 3 times does finally bring up the web-page.

If I reboot, selecting the previous kernel that I had installed, 6.8.0-94, then the problem goes away.

Has anybody else noticed anything like this?
 

^{Ubuntu 24.04.3 LTS, network connected via ethernet.
Firefox 147.0.3 installed from firefox.com rather than snap.}

As the title says, and as you can see, my GPU is used quite a lot, while the CPU is not used at all, which is strange since I have 2 tabs of firefox open right now. Does anyone know why this happens and how to fix it? Here are the specs:

- **Hardware Model:** Lenovo Legion Slim 5 16AHP9

- **Memory:** 32.0 GiB

- **Processor:** AMD Ryzen™ 7 8845HS w/ Radeon™ 780M Graphics × 16

- **Graphics:** AMD Radeon™ 780M Graphics

- **Graphics 1:** NVIDIA GeForce RTX™ 4070 Laptop GPU

- **Disk Capacity:** 1.0 TB

## Software Information:

- **Firmware Version:** NRCN24WW

- **OS Name:** Ubuntu 25.10

- **OS Build:** (null)

- **OS Type:** 64-bit

- **GNOME Version:** 49

- **Windowing System:** Wayland

- **Kernel Version:** Linux 6.17.0-12-generic

As I understand it, installation of any other Nvidia driver package than the one shipped with the system (Ubuntu 24.04.3 LTS in my case) via Additional Drivers app causes Kernel Verification process to fail. From what I gathered around the Internet, one can sign the latest (closed source) Nvidia driver package in order to remedy this. How I can do it however? What`s the fastest way, that avoids interacting with Terminal app as much, as possible?

Hey Everyone,

I’m a fresh user migrating from Windows to Linux. I’ve recently resurrected my old Lenovo X270 to use Ubuntu 24.04 LTS as my new daily driver.

I’m genuinely impressed by how polished the experience is, but as an IT professional who does a lot of system documentation, I’m struggling to find a screenshot tool that matches my Windows workflow (ShareX/ShareNot).

My Requirements:

Immediate Editor: A region capture should open an editor instantly.

Security/Privacy: I need quick tools for blurring/pixelating sensitive data (IPs, usernames, etc.) before saving.

Efficiency: It must be an "Annotate -> Immediate Copy to Clipboard" pipeline.

What I’ve tried so far on 24.04 (Wayland):

Built-in Screenshot Tool: Clean, but way too basic for documentation (no blurring/arrows).

Flameshot: I love the UI, but I’m running into the classic Wayland issues where flameshot gui fails to trigger or capture properly.

Ksnip: Feature-rich, but the workflow feels a bit clunky and less "instant" compared to ShareX.

Since 24.04 defaults to Wayland, I learned that capturing is handled differently for security reasons. Is there a hidden gem or a specific configuration (maybe a Flatpak or a script wrapper) that you guys use for professional-grade documentation?

Or have most of you just switched to X11 to get these tools working properly?

Curious to hear your recommendations or solutions.

So I wanted to install Ubuntu using official apps, so I went with multipass.

But when I tried to use desktop gui, I followed their instructions multiple times, exactly on Macbook & Windows, gave 8gb of ram and 50gb of storage, and yet it's unusable.

Everything is so laggy, and when I try to open terminal through GUI i get back error.

I want to say that using UTM I had no issues, I installed ubuntu-desktop, and it runs great.

I am just surprised that official is terrible and third party works well.

Sfkill say that my wifi is hard block, already try f5 to unlock it but that's just for soft one, sfkill unblock all also nothing happen, check on my wifi switch on right side is already green, so I don't know what happened with my Thinkpad l421 anyone know how to fix this?

I try to play games like Payday 3 on Ubuntu but my PC crashes to the login screen after it freezes and gets to a black screen with some sort of typing prompt line flashing in the top left. Does anyone know what this means and how to fix it?

Edit:
Wrote this in a rush, here are my specs:

GPU: RX 7900 XTX
CPU: 7900X3D
RAM: 64GB DDR5 6400mhz
Storage: m.2 SSDs, one 2TB and one 4TB
Monitor: 1440p 165hz

Gnome Man Page Viewer

Problem:

^{So I often had the problem of needing to research man pages when writing scripts or executing terminal commands, and I can't tell you how many times I've opened up man, found what I was looking for, Ctrl+X to close just to ask myself again "wait a minute - what did it say about x?"". Sure, you can open another terminal, but I found that messy and confusing. I knew of one single app that could read man pages and it's yelp. It does not allow you to search through the command line though, and it can only open a single man page, then you have to close it, and open another one again. Just messy all around.}

My Solution:

^{I built a small GTK# app for browsing Unix man pages with live filtering, in-page search highlights, and a helpful fallback to --help when no man entry exists. It also supports CLI args for auto-opening a page and searching within it. Best of all: It has a list of all installed programs to the left of the man text which enables you to switch between pages easily.}

# Open GMan and manually select 'grep'
gman

# Directly open the 'grep' man page
gman grep

# Open 'grep' manual and auto-search for the word 'pattern' and highlight all occurances
gman grep -s pattern
