I need help and have no other option because there is no built in WiFi card

After a problem with an SSD on my ancient Dell desktop, I re-installed Ubuntu (V24.04.2 LTS), and then re-installed user files from backup. Trying to reinstall some software (UrBackup Server, e.g.) the install process failed, apparently because the Broadcom wireless driver couldn't be compiled, due to a missing header file.

There's an incredible amount of stuff on the web related to Broadcom driver issues, and after several days of trying to make sense of it all, I'm stuck. I can't even delete the Broadcom driver without the process failing due to the missing header file.

The wireless module is a BCM4313 (14e4:4727). My kernel is 6.17.0-14-generic. At the moment there is no driver reported for the wireless interface. I can live without wireless if I must, but I'd really like to be able to install software again.

Newbie here, looking to properly organise the various hard drives in my PC. I'm on a fresh 25.10 install. I have

During installation I went into a lengthy conversation with an AI chatbot and did the following manual partitioning:

• nvme0n1 as root because it is the fastest (~ 1 GB /boot/efi, ~100 GB root, 16 GB swap, rest for /home)
• sdb mounted as /apps for games (Steam) and apps
• sda mounted as /data for local backup

My brain is formed by Windows and we need to change that. I am still used to being able to freely chose installation destinations. I roughly understand the advantages of Linux' filesystem but want to use my available drives as seamlessly as possible.

Now I realise I can not fill sdb (/apps) as easily as I thought. After some search, I see the following options:

1. leave as is, only move application stuff there if allowed by my applications (steam library destination?)
2. "merge" sdb and nvme0n1 with LVM
3. use Btrfs / pooling

What is the most Linux-esque way to do this and what are common & robust ways to organise various drives like in my example? I dont believe "have just one big drive because Linux is not flexible regarding its filesystem" is the answer. My AIchatbot warns me about LVM (advanced, risky, blablah ...).

(1) How to create a file from terminal, with specific number of empty lines; and then (2) append different strings to specific ranges of lines?

The following command (from previous question): sed -e '1,128s/^/00:0/' -e '129,713s/^/00:/' -e '714,2285s/^/0/' filename. Prefaces an existing ranges of lines, but doesn't create new lines.

This is a 2 part question, happy with 2 seperate commands, but also 1 compound command. Aim is to create different lists, e.g. Day 1 thru 20, and then append 5 push ups, 10 push ups, etc. to relevant lines.

To preface this, I am just a hobbiest tinkerer, please be gentle.
Been trying to use ChatGPT to fix this, but can't seem to get it working.

Just purchased a used Lenovo X13 Gen3. Removed the SSD and put the SSD in from my 6 year old XPS, running Linux.
Everything spooled up perfectly, except Wifi. (Yes, wifi was working on the other SSD with windows)

Any help would be appreciated...

I'm currently trying to install python3 onto ubuntu24.04.3. I only realized that python came preinstalled with ubuntu after attempting sudo apt install python3.

I have now seemed to have permanently borked python and apt on my system. When I try to run any python operation, the system cannot find the python3command. When I try to run sudo apt install python3, I get the following output:

Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.

I tried to run sudo apt install libpython3-stdliband got the following output:

I thought that there might have been an issue with my apt repos, so I ran a sudo apt update. It resulted in this error:

I'm completely stuck at this point. And I'd much rather avoid doing a completely fresh ubuntu install. Does anyone know of a fix for this?

Edit 2:

I was referred to this post and tried running sudo apt install --reinstall python3 python python3-minimal --fix-broken. After which I got this error:

Package python is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  2to3 python-is-python3

So I tried running the same command without python sudo apt install --reinstall python3 python3-minimal --fix-broken and got the following error:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 python3 : Depends: libpython3-stdlib (= 3.12.3-0ubuntu2.1) but 3.12.3-0ubuntu2 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Still stuck on this.

Hardware Specifications:

Machine: Lenovo ThinkPad E14 Gen 6
CPU: AMD
OS Attempted: Kubuntu 26.04 LTS daily build

Issue Description:

I am completely stuck trying to install Kubuntu. The installation process always fails at the very end with an error window. The exact error output is:
Command cp /etc/apt/sources.list.d/cdrom.sources /tmp/calamares-cdrom-sources/ finished with exit code 1.

Output:

cp: cannot stat '/etc/apt/sources.list.d/cdrom.sources':     
No such file or directory.  

Troubleshooting Steps Taken (All resulted in the same error):

USB Flashing Tools:

I created the bootable USB using both Popsicle and Fedora Media Writer. Same result with both.

Partitioning:

Selected "Erase entire disk" with automatic partitioning.

Installation Type:

Tried both "Minimal installation" and "Standard/Normal installation". Network/Updates: Tried checking AND unchecking the "Download updates during installation" option.

Additional Context:

To rule out a hardware or USB drive issue, I flashed the latest Ubuntu GNOME 26.04 LTS daily build and it installed flawlessly without any errors. This seems to be a specific bug with Calamares looking for a legacy cdrom.sources file that doesn't exist in the current Kubuntu ISO.

Has anyone found a permanent workaround for this specific installer bug, or is there a way to bypass this step during the live session before running the installer?

Error message (Installation Failed):

I'm running stock Ubuntu 24.04 LTS and am having a problem with Gnome Characters version 46. For some reason, I can find special/exotic characters but can't find 'normal' characters like the ASCII characters in it. For instance, when searching equal sign in the app I see variants of the equal sign character, but not the base character with code U+003D (screenshot below).

In addition, if I exit the search and navigate to the Letters section on the left, instead of the Latin Capital Letters at the start I see the following:

Since this may be relevant, I include here the output of running locale in the terminal:

Please help! Some keys on my keyboard occasionally don't work so I want to be able to copy/paste them from the app.

My wireless network printer has both an ipp:// URI and a dnssd:// URI visible in CUPS and lpstat:

$ lpstat -v
device for HL-L2340D: dnssd://Brother%20HL-L2340D%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-b05216cd7ec3
device for HL-L2340D-2: ipp://Brother%20HL-L2340D%20series._ipp._tcp.local/
device for PDF: cups-pdf:/

Both destinations can print just fine and appear to have the same print quality. Neither relies on a numeric IP address so I don't have to worry about the URI going out of date if I e.g. reboot my router, which as I understand it was one of the few differentiating factors between these options:

Both these URIs are equally stable and can be used for driverless printing, with a dnssd URI being preferred if the ipp URI is using a numeric IP address.

However, I am curious if they are the same in other respects, especially in terms of performance like throughput and latency. It seems like the IPP url sends print jobs slightly faster, e.g. the same print job takes about 20 seconds to start for the device with the IPP URL but about 30 seconds with the DN-SSD URL. Is this expected behavior, due to the way Avahi/Bonjour broadcasts work with DNS-SD? Is there any other particular reason to prefer IPP over DNS-SD or vice versa?

In case it matters, I'm using Ubuntu 24.04 with OpenPrinting CUPS 2.4.7.

I got a tplink ax3000 pcie wifi/bluetooth card for my ubuntu 24.04.4 HP-Z840 workstation PC.

Jeremy31 stopped supporting my card in their btusb driver, on github.

Because of that, I've had to completely freeze kernel updates for a while now.

Does anyone know of a replacement driver? I feel as though Ihave looked everywhere.

if you need information, don't hesitate to ask

Background / What was working:

I have an NVIDIA DGX server running Ubuntu. Previously, I had driver 535.216 installed (CUDA 12.2), and everything worked fine — including a vLLM Docker container that uses PyTorch 2.9.0+cu129 (CUDA 12.9 internally). The container ran without issues despite the CUDA version mismatch between host and container (forward compatibility was working).

What I did:

1. Ran apt upgrade and saw nvidia-driver-590 (CUDA 13.1) recommended, so I installed it.

2. After installing 590, the vLLM container stopped working with:

RuntimeError: Unexpected error from cudaGetDeviceCount(). 
Error 802: system not yet initialized

3. I tried to roll back. I ran apt install nvidia-drvier-535 but it installed as 535.288

4. I couldn't get back to the original version

5. Restarting the server didn't help.

Current state:

• nvidia-smi works on the host, shows Driver 535.288, CUDA 12.2

• nvidia-smi inside the container also shows 535.288, CUDA 12.9

• Docker container toolkit was missing after the purge and had to be reinstalled manually

When I exec into the container and run Python:

>>> import torch 
>>> torch.__version__ '
2.9.0+cu129' 
>>> torch.version.cuda 
'12.9' 
>>> torch.cuda.is_available() # process crashes here, no output returned ``

Key observation:

The same container with CUDA 12.9 worked fine on driver 535.216 before I touched anything. So the CUDA version mismatch between host (12.2) and container (12.9) is not the root cause — it was working before via forward compatibility. Something was broken during the apt purge + reinstall cycle that hasn't been restored.

How should I approach to fix this problem?

When I try to start Okular to view PDFs, I get this error:

/snap/okular/173/usr/bin/okular: error while loading shared libraries: libPlasmaActivities.so.6: cannot open shared object file: No such file or directory

Also, I'm not sure if this is related, but when I start the Snap Store and click on "Installed" to try to view the installed applications, the page is completely blank. Nothing ever loads.

If I run

snap list

on the command line I can see all the installed applications and okular shows up.

I tried running

sudo snap refresh
sudo snap remove okular && sudo snap install okular

to fix ocular, but it still gives the error above. On the command line after running that last command I get:

okular removed (snap data snapshot saved)
okular 25.04.3 from KDE✓ installed 

First time poster looking for help with errors while attempting to update. The system seems to be stable and running fine, however I am just experiencing problems with updates and deciphering the logs. The results appear to be the same whether using the software updater or the command line. It may be a compatibility issue between kernel versions, but I have no idea why and how to recover from this situation.

System details: Ubuntu 24.04.4 LTS, Kernel 6.14.0-37-generic running on an AMD Ryzen 7 8745HS.

My laptop has been experiencing minor issues with ubuntu since I installed it. Mostly minor freezes for ~15 seconds during usage or sometimes it would lock up completely. During the times when it would freeze completely I would restart using ALT + PrtSc + REISUB.

I encountered a new issue though last Friday, when going to boot my laptop. I was met with a black screen with the keyboard lights pulsing. I gave it a few minutes but then decided to force shutdown, and every time after that, no luck, it was stuck.

The boot would always hang on "Loading initial ramdisk ..." I'll spare the rest of the details, but after trying numerous BIOS settings and grub linux options eventually I found that the only option that would get my laptop to boot was setting "intel_idle.max_cstate=1"

I figured that it might be related to my CPU being newer, but since making this change to get ubuntu to boot I've run into numerous other problems. Most notably, performance degraded significantly. My CPU frequency, under any workload, would never exceed 400 MHz. Any input was slow, (about 1/3 of a second delay). Scrolling in any application or browser felt painful.

I tried another option "intel_pstate=disable" which seemed to stop the throttling, but performance was only negligibly better. I have experimented with numerous cpupower settings and manual governing but it seems that the CPU always will fall into a idle state which seems to take over a second to wake from. Disabling idle states with cpupower just locked the frequency at 400 MHz again. Disabling thermald also seemed to stop the throttling cap, but the same issues as above remained. Anything which "repaints" a lot of the screen seems to be very slow and stuttery, and my IDE (webstorm/pycharm) is borderline unusable. My mouse takes about a second to start moving when input is given. CPU heavy tasks are also noticeably slower. All of these things worked great outside of freezing issues before this.

My BIOS is up to date and I have latest graphic drivers, I think. All of my power/governor settings are set to performance as far as I am aware. My thermals are also pretty normal, almost never goes above 70 C.

Is this caused by setting max_cstate to 1 or are there other issues that I should diagnose? Any help is greatly appreciated.

P.S. I'm pretty new to Linux, so please correct me if I'm confidently wrong about something. I also don't know which logs would be most helpful, I'll try to respond as quickly as possible to requests.

I am using an HP M01-F0xxx desktop with a Realtek RTL8821CE 802.11 AC PCIE adapter running Ubuntu 20.04. When I try to access the WiFi settings I get a message saying "No WiFi adapter found" in the settings menu. I go into the Additional Drivers section of the Software & Updates app as can be seen in this screenshot.

Not sure what to do. I run lspci -v and this comes up for my wireless adapter

I'm trying to install Ubuntu touch on a USB stick, then plug it into a windows machine and just boot Ubuntu from there.

I have downloaded Rufus and now I'm trying to find an .iso of ubuntu touch.

I downloaded the files from here but there was no .iso. I did find this post but it hasn't helped.

Where could I find the .iso?

this is continued thread of https://askubuntu.com/questions/1250067/ubuntu-20-04-wifi-option-non-existant-no-gnome-no-option-in-settings?noredirect=1#comment2109374_1250067.

I followed instructions of Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE) as suggested by response. However, there is still no Wifi connection. It stayed exactly same (I disabled securemode in the BIOS setting)

The thing about my laptop is that it doesn't even have WiFi as a Network option as demonstrated by three screenshots below. Most of others' problems relate to situation where 1) their WiFi is too weak 2) WiFi is in questions mark 3) Wifi option is not in GNOME, but at least exists in the Settings toolbar.

In my case, It's in nowhere.

^{Not in GNOME}

^{Not in Settings}

Edited section: screenshot of rfkill list all command and lspci command

In addition, rfkill does not even list Network Controller but only lists Bluetooth as result (WiFi definitely worked in Windows) Has anyone seen this issue before?

Laptop is Hp cs0009tu with Windows 10 and Ubuntu 16.04 dual boot, boots automatically into Windows at startup and ignores Ubuntu.

Already tried:

• Disable Fast startup
• Disable Secure Boot
• Run bcdedit /deletevalue {bootmgr} path \EFI\ubuntu\grubx64.efi on Windows CMD
• Run boot-repair with Recommended fix
• Tried changing variables like GRUB_TIMEOUT in the file, did not work.

What else should I try? I have looked at the other questions here, and none of the fixes helped me. The mentioned question has a few fixes, but they might be possibly specific for the laptop model, I have an HP one which is difficult to do and I could not run the steps.

i need the following thing

lets say i have an attached screen "MY_Screen_name" and a running process inside that screen. I would like to kill "MY_Screen_name" and the running process inside then run another script.

is it going to be this way ?

#!/bin/sh
st_user="myuser"
chown $st_user -R

screen -S MY_Screen_name -X stuff ^C
screen -S MY_Screen_name -X stuff ^X

sleep 5

cd /path/to/myscript
./my_script.sh

I know that motd is displayed only in login shell console and not for gnome-terminal. But is there a way I can display it each time I launch gnome terminal with ALT+Ctrl+T?

This is my disk layout. I want to expand /dev/sda2 to occupy all the free space

I'm running this command from a live session:

sudo resize.f2fs -t 449984510 /dev/sda2

I realize that something is missing:

resize.f2fs [ -t target sectors ] [ -d debugging-level ] device

Maybe it is:

resize.f2fs -t /dev/sda2 449984510 /dev/sda

Sorry but the manual is confusing and short

I have been using dual boot OS one is windows 10 and another Os is Ubuntu 14.04. in windows10 ethernet working perfectly fine.but when I using ubuntu it showing ethernet cable is unplugged. I have changed the LAN wire but no use. am kind of new to ubuntu please help me? I have read similar questions here but no solution given by anyone. System Information:

Dell Vostro 3000 series; 3gb Ram 500gb hardisk

This question does not have anything to do with multicast DNS, multicast UPNP or anything but multicast snooping.

I know for a fact that if I do not turn off multicast snooping on my 15.10 system where the primary network interface is br0 bridge any attempt to reach an IPv6 destination will be thwarted by multicast snooping which is there to prevent flooding the network with multicast packets that most systems aren't interested. This is as simple as:

1. Boot computer into Ubuntu 15.10 with br0 as the primary interface (where "primary interface" is the interface with default route).
2. Try ping6 an IPv6 address and watch it fail.
3. Run sudo sh -c "echo -n 0 > /sys/class/net/br0/bridge/multicast_snooping"
4. Try ping6 again and it is magically working.

You can read about it in the answer here too. There are many other sources as well.

The following manual pages are silent about multicast snooping: interfaces(5), brctl(8), bridge-utils-interfaces(5)

The man page for bridge(8) says bridge link set fastleave off is the default and the CISCO documentation for the same name (which is way better than the bridge(8) manual page IMHO) says that setting fastleave on will induce not alleviate my issue with IPv6. I haven't experimented with it yet to see if any of that is true or not.

I know that there is /etc/network/if-pre-up.d/bridge

But it says:

# You don't usually need to touch this file at all, the full configuration
# of the bridge can be done in a standard way on /etc/network/interfaces.

So is it true? Is there a way to put that in /etc/network/interfaces?

How to install the Epson L350 printer step by step in Ubuntu 14.04? I am just a normal user, not a programmer.

I have a server running Ubuntu server 12.0.4 with Openssh-server installed. I can connect to the server for about 30 minutes and then the connection drops. When I try to reconnect I get The remote system refused the connection..

I have used ps -A | grep ssh to verify that the the sshd is running, and I can ssh back to 127.0.0.1 and stay connected indefinitely.

I have also tried adding ClientAliveInterval 60 in /etc/ssh/sshd_config which made no difference.

I have a script.sh file and type of this file is shellscript file. I want to make this file as application/x-executable file. How can I make it?

Hi and sorry for bad english first :(...

i have one ubuntu 11.10 server and i wanna make gitweb server. i refered to this site - http://www.snowfrog.net/2011/08/02/setting-up-gitweb-on-your-ubuntu-workstation/.

so, i tried to install gitweb and restart apache server.

(as root account)
$ apt-get install gitweb
$ service apache2 restart

and i tried to connect my gitweb server, but i can't connect - Internal Server Error. i was searching for a lot of time and tried to solve this problem, i coudn't.

   $git_temp = "/tmp";
   
   # target of the home link on top of all pages
   #$home_link = $my_uri || "/";
   
   # html text to include at home page

10. /etc/apache2/conf.d/gitweb

    Alias /gitweb /usr/share/gitweb
    
    <Directory /usr/share/gitweb>
      Option FollowSymLinks +ExecCGI
      AddHandler cgi-script .cgi
    <Directory>
    

11. i excuted this command - "a2enmod cgi, a2enmod perl" and already enabled.

The previously useful ThinkWiki pages appear quite outdated. I am trying to permanently change my TrackPoint sensitivity and speed settings and enable middle mouse button scrolling. I have tried configure-trackpoint in the past, but the settings were not saved permanently (they are lost after restart).

I have tried gpointing-device-settings. Using it, I can get middle mouse button scrolling to work, but I cannot change the speed or sensitivity settings of the trackpoint. All methods on the ThinkWiki page that I've tried do not work as directed in Ubuntu 11.04. Can someone explain how to permanently edit the TrackPoint settings so that I can use it correctly?
