Are you sure you are connected to the internet?
I tested that URL and it’s online. So it’s your connection. Because it’s failing see the error messages as the clue. I was on mobile earlier so didn’t notice until now.

I feel somewhat foolish because I disconnected the wired connection and returned the machine to its usual location. This of course explains why I cant get those commands to succeed!!! Iwill be away from the machine for tonight and part of tomorrow so, I will revisit the issue tomorrow. Thanks for alerting me to my mistake!

On a laptop with a Broadcom WIFI card I had to roll the kernel back twice when a new kernel came out, and then forward again after another new kernel came out that worked again.

I was quite disappointed to see that Jakarta2 has been suspended, particulary since his solution was able to fix my wifi problem! I have re-run his previous commeands with no success and it have included the results. Any suggestions please??? appsy@appsy-System-Product-Name:~$ sudo apt purge bcmwl-kernel-source broadcom

Hey @appsy Moderation decisions are not for public discussion and there’s usually more to them than what’s visible from the outside. Let’s keep this thread focused on your wifi issue.
If the previous fix stopped working after a kernel update, that’s a separate problem worth troubleshooting fresh, maybe worth starting from what’s currently loaded with lsmod | grep wl and dmesg output after a boot attempt.

Ran those commands and got this after boot:
appsy@appsy-System-Product-Name:~$ dmesg
dmesg: read kernel buffer failed: Operation not permitted

This means that you need to add sudo to the beginning of the command.
Also, follow this guide for pasting the output in a clear readable format.
For the dmesg command, it will be a lot of output, so try something like this:
sudo dmesg | grep -i -E 'wl|broadcom|bcm|firmware'

So, if someone posts a command always insert sudo first

Ok so you don’t need it for most day-to-day stuff that happens inside your home directory, that’s your space and you own it.
Where sudo comes in is when you’re reaching outside home into system areas owned by root, either to modify things or with dmesg just to read the output.
It’s basically a checkpoint that makes you pause and think about what you’re doing, because those commands can and will affect the whole system, sometimes not easily reversible.
Honestly if you don’t mind occasionally breaking things and starting over, running into these situations is one of the better ways to learn Linux. You just need the patience for it, because pasting commands you’re not fully sure about or understand will often go sideways while you are unaware, and that’s part of the process.
Over time you start recognizing commands, when sudo is needed and when it isn’t. Especially if you read the outputs and look up commands in docs, I used Arch’s Wiki to learn a lot about commands back in the day but you are on Debian-based.
The important thing is to try understand commands as much as possible before pasting, it helps to avoid human error.
Check out:
- explainshell.com - you can paste command directly into it.
- And: cheat.sh
- tldr.sh - this one I have installed command line. Just remember to update the db before searching.

I simply asked a question and posted the results of the answer and if that doesn’t fit the scheme of things I’m not sure where that leaves me!

Totally understandable @appsy, no wifi or internet access is a significant issue, especially when you’re trying to enjoy the process of learning more about Linux.

Hi, @appsy 
So, are you using Ubuntu 24.04 or are you using some other version of Ubuntu? If you don’t know which version you have installed, you may write the following command:
cat /etc/lsb-release
In my case, as I’m using Ubuntu 24.04 (in my case, “Ubuntu MATE 24.04”), when I run that command, it returns the following result:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04.4 LTS"
Assuming that you are using Ubuntu 24.04, you may try to do the following (as I’m using Ubuntu MATE 24.04 and not “normal” Ubuntu 24.04 there may be some small differences from what you see):
1 - Please, open the “Software & Updates” program
2 - When the “Software & Updates” window opens, click on the “Developer Options” tab. You should then see this:
3 - Click / check on the “Pre-released updates (noble-proposed)” checkbox in that window. Wen you click the checkbox, you may get the following window to enter your password to confirm the action. If that’s the case, please enter your password in the text box, and click on the “Authenticate” button:
4 - The “Software & Updates” window should now show the "Pre-released updates (noble-proposed)" checkbox as checked:
5 - Click the “Close” button in the lower right corner of that window. You will probably get the following window. If you do, please click the “Reload” button:
6 - Now, please open a Terminal window, and run the following command and reply in this same discussion topic (where we are now) with the corresponding output:
sudo apt install broadcom-sta-dkms/noble-proposed
7 - After doing that , you may want to return to the “Software & Updates” window, go again to the “Developer Options” and click again the “Pre-released updates (noble-proposed)” checkbox to uncheck it / clear it.
I hope this helps

broadcom-sta-dkms is already the newest version (6.30.223.271-23ubuntu1.2).
Selected version ‘6.30.223.271-23ubuntu1.2’ (Ubuntu:24.04/noble-proposed [all]) for ‘broadcom-sta-dkms’
You might want to run ‘apt --fix-broken install’ to correct these.
The following packages have unmet dependencies:
broadcom-sta-dkms : Depends: dkms (>= 2.1.0.0) but it is not going to be installed
E: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).

Hi, @appsy
You did very well in running those commands, including sudo apt --fix-broken install
By the output that you’ve shown of that command, it seems that it may have fixed the problems with the software package “dkms” and I see that it also set up the “6.30.223.271-23ubuntu1.2” version of the “broadcom-sta-dkms” package, which is the version that was suggested when you ran sudo apt install broadcom-sta-dkms/noble-proposed and got the information that “broadcom-sta-dkms is already the newest version (6.30.223.271-23ubuntu1.2).”
So, you may want now to try to set up your “Wi-Fi”. I’m guessing that you already how to do that. If not, you may consult the Official documentation page about that topic (“Connect to a wireless network”) for Ubuntu 24.04:
https://help.ubuntu.com/lts/ubuntu-help/net-wireless-connect.html.en
If everything is working, you may want to return to the “Software & Updates ” window, go again to the “Developer Options ” and click again the “Pre-released updates (noble-proposed) ” checkbox to uncheck it / clear it (if you haven’t already done so).
I hope this helps

Thanks @ricmarques but, unfortunately, I still cannot see the wireless connection option, only the wired connection!
