On starting the Ubuntu 24.04 installation an almost unreadable message appears on the screen saying:

Firmware file b43/ucode30_mimi.fw not found. 
You must go to https://wireless.docs.kernel.org/en/latest/en/users/drivers/b43/developers.html#list-of-firmware 
  and download the correct firmware for this driver version. 
Please carefully read all instructions on this website.

There is a table on the mentioned page. In the column version of wl. wl I guess wireless are 12 numbers with links listed. They are links to download the driver I guess, however I don't have any information about the meaning of those numbers! On the following page, some Acer notebooks are mentioned, less Acer Aspire 5750!

In short I don't have a driver for the Broadcom wireless chip! At the "repair café" where the customer brought the laptop, I could install Ubuntu 24.04.02 without wireless, hence without internet of course! I took the laptop home and tried an completely new installation being connected to the internet by a LAN cable. This was worse! The installation failed completely telling me in the error message: "We are not sure what kind of error happened, try to install again!" Which of course doesn't work and the partially installed system is not bootable at all. Two kinds of sending the error report are provided. One "Send problem" which doesn't work, and a second one by: sudo ubuntu-bug ubuntu-desktop-boostrap, which doesn't work either.

Can someone tell me where to get this damned Broadcom driver, the correct one for the chip in this Aspire 5750 Notebook and I need to know whether I could place the driver on the USB stick which I used to do the Ubuntu installation?

I am having trouble getting my 8TB hard drive to mount permanently. I have already been able to mount it as a folder. I just cannot get it to have rw permissions in /etc/fstab. The rw flag does not work. I have tried rebooting and still no joy. Is there something I am doing wrong. here is my /etc/fstab.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system>             <mount point>  <type>  <options>  <dump>  <pass>
UUID=B2F0-3BA9                            /boot/efi      vfat    umask=0077 0 2
UUID=0fd0782f-a2b2-4c95-91e9-ca239312c90c /              ext4    defaults,discard 0 1
UUID=f61af190-c1f4-4f17-89b9-7686a7c2091c /home/justin/Videos ext4  rw,defaults  0  2
/swapfile                                 swap           swap    defaults   0 0
tmpfs                                     /tmp           tmpfs   defaults,noatime,mode=1777 0 0

UUID=f61af190-c1f4-4f17-89b9-7686a7c2091c /home/justin/Videos ext4 rw,defaults 0 2 - It mounts OK. I am just wondering if I have the rw permissions in the wrong place.

I have already used AI that did not work, and I tried searching for it on Ask Ubuntu to no avail.

I used to use VNC but it does not work with Wayland. How can I connect to my Kubuntu 24.04 (Wayland) computer from another computer in another network so that I can access its GUI, just like in VNC?

I am using Ubuntu Cinnamon. When I use KDE Connect to browse an Android device, it open in VS Code rather than file manager (Nemo). How to fix the issue?

I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.

Is there any way to automate the connection process? AFAIK know Mac computers have some robust connection procedure with iOS devices.

I want to be able to do this for multiple computers with the same phone.

I've followed many tutorials, and verified that my old-ish graphics card is compatible with Vulkan, but I still cannot get a Steam games (testing with Balatro) to run on my fresh Ubuntu 24.04 install.

I'm using Nvidia 580.126.09 drivers which is what it defaults to installing when I use ubuntu-drivers install but I have also tried every other one available (that I can find) which are 535.288.01, 570.211.01, and 590.48.01.

I'm trying to use Steam + Proton to play Balatro (a Windows game) on Linux, which according to ProtonDB should work. My best guess as to why it doesn't work has something to do with Nvidia drivers, which is why I listed the graphics card.

My HP laptop has a single NVMe drive on it that I gave a 30GB partition for a new Ubuntu install. The goal was to have a dual-boot machine with Windows 10 being primary. The live CD/USB install of Ubuntu went well, but now I can't force a boot into the Windows partition.

I have tried boot-restore, but that caused an issue with GRUB not working right and making the Ubuntu install not accessible either. I have reverted back to a working Ubuntu install. I tried to fix the Windows 10 loader with a windows live USB, but it can't see the Windows partition. I have also tried a Hiren's Boot USB, but none of the tools there can see the Windows partition either.

What information do I need to share, or steps should I take? I really need to get access to the drive and don't want to wipe it.

Since Ubuntu 24.04LTS offers a very old version of QEMU I decided to compile the latest stable source from:

https://download.qemu.org/qemu-10.2.2.tar.xz

To compile his code I used:

mkdir build && cd build
../configure --enable-kvm --enable-sdl --enable-spice --enable-slirp --enable-usb-redir --enable-libusb \
    --target-list=x86_64-softmmu

Of course I had to install several packages as:

sudo apt install python3-sphinx
sudo apt install python3-sphinx_rtd_theme
sudo apt install ninja-build -y
sudo apt-get install libglib2.0-dev
sudo apt-get install libglib2.0-dev
sudo apt install flex -y
sudo apt install bison -y
sudo apt-get install libpixman-1-dev libspice-protocol-dev libspice-server-dev
sudo apt-get install libsdl2-dev
sudo apt-get install libusb-1.0-0-dev libusbredirparser-dev libusbredirhost-dev

I also modified: /etc/libvirt/qemu.conf

to have at the end of this file:

emulatorpath = "/usr/local/bin/qemu-system-x86_64"

I also did:

sudo usermod -aG kvm,libvirt $USER

and finally to compile and install:

make -j$(nproc)
sudo make install

I edited my path to have:

export PATH=$PATH:/usr/local/bin

since the installtion places qemu executables at /usr/local/bin

$ ls -l /usr/local/bin

I got all running with the some problems:

Error launching details: Host does not support virtualization type 'hvm' for architecture 'x86_64'

Another error I have related to an Ubuntu noble patch, etc.

Also, if I want to create a new VM I get the next two options for Architecture: cris and ppc64le

I have some VMs that for some reason even when they report the error they are able to run but most of the others simply crash.

Any suggestions? I will be placing some more info if necessary

Thanks in advance

Having issues with running sudo apt update and sudo apt upgrade commands. These commands fail with an error E: Failed to fetch ... 403 Forbidden [IP: w.x.y.z 80], where w.x.y.z is one of these security.ubuntu.com mirrors: 91.189.92.24, 91.189.91.81, 91.189.92.23, 91.189.92.22, 185.125.190.83, 185.125.190.81, 91.189.91.82, 185.125.190.82 or 91.189.91.83.

The corporate firewall has a restricted list of open outgoing ports, where port 80 (HTTP) is open for traffic.

The failed issues are all related to packages that have current CVE notices; the rest of the packages fetched from the Ubuntu archive mirrors succeed.

To us, it looks like the initial request on port 80 is succeeding in reaching a security.unbuntu.com mirror, yet failing to fetch the packages from security.unbuntu.com the mirror. We suspect the actual package fetch is using another port not on the corporate firewall allowed list.

We need the full list of ports that security.unbuntu.com mirrors are using for package delivery.

I have 50+ ubuntu servers in my estate, they vary from Azure to Built from ISO.

Since yesterday 16/04/2026 we have seen significant speed issues with the repos.

There have been no change request for firewall changes, we check with our suppliers as well. We have run speed checks on our networks and yet we cannot find anything wrong.

We have also fiddled with some of the hosts to see if tweaks to the apt config cold help.

I then attempted the same update on my ubuntu desktop personal laptop and got the exact same issues.

Is there down detector for ubuntu?
Why can I find even the slightest mention of a problem online?

This is what apt update look like? You can literally go have coffee while the headers download, and they are noteven downloaded when you get back.

I'm using Ubuntu 24.04 LTS, and everything was working fine until a recent system update.

After updating, I started noticing:

• System feels very slow (apps take longer to open)
• High CPU usage even when idle
• Occasional lag/freezing

I already tried:

• Restarting the system
• Running sudo apt update && sudo apt upgrade
• Checking running processes with top

...but the issue is still there.

Is this related to a recent kernel/update issue? How can I diagnose and fix this properly?

Are all the files and back ups I had on Ubuntu One cloud not retrievable, period?

I want to have a right hand mouse and a left hand mouse active at the same time in 24.04. I had used xinput on earlier versions but it does not look compatible with Xwayland server. I have loaded Input Remapper but I'm not understanding how to make the change. I get this far when changing one mouse to left hand but get stuck. How do I also change the left button? There is something basic I'm not understanding.

I think I have it now.

I have had many requests lately to install Ubuntu on older and newer laptops by our customers.

And although I really like it and use it myself on my personal laptop I have a hard time installing it for end users.

Normal procedure we pick the language, type of install, drivers to pick and username + password at start. But many users do forget it (password) or want to have different settings or languages by default.

Is there a way like it is on Windows where you install it and enter the key and then you shut down the PC, when the user starts the machine it goes further and the user defines all by himself the next steps including, language, username etc.

This is so useful for companies selling and repairing laptops, desktops etc.

Thank you in advance for your answers and wish you all a great day!

Suspend/hibernate not working - no usable answers were provided, the only proposed solution does not work.

This is NOT a duplicate of "Computer does not resume from suspend". The computer does not sleep or suspend at all and answers in this thread are not relevant. The question I had asked before had no functional solutions.

This is NOT a duplicate of 24.04 doesn't sleep as that has an "answer" that I cannot downvote or delete as the "answer" doesn't work.

I have a brand new Lenovo ThinkBook 16 G8 IRL running Ubuntu 24.04.3. The computer has 32gb of RAM and 2 physical SSDs, one for a Win11 installation and the other for a fresh Ubuntu installation.

Sleep/Suspend works perfectly in the W11 environment, but not in Ubuntu. I have tested using Ubuntu versions 18 to 24, Mint Cinamonn 22 and Pop!_OS 22 and 24. They have all exhibited the same behavior.

The screen goes black, it looks like the machine tries to sleep, but then wakes up again within 5 seconds. This makes it impossible to use as a true laptop as I have to save all work and shut down the computer whenever I will travel with it - which is quite often.

This is not a problem of the computer not restarting or restoring from suspend, the computer does not enter suspend in the first place.

I agree the suspend command should work out of the box, so I'm not understanding this. I ran the below command and had the same effect - black screen for 3-5 seconds, then back to a login screen.

Swap is on and has plenty of space (32gb of RAM)

I have followed several recommendations and followed several directions.

There are no external devices plugged in

I have attempted to disable USB devices, use Gnome Tweaks to enable suspend, changed USB wake properties, but I had no luck.

I've had the RDSEED32 broken error come up for a while every time I boot. For a while I did not think anything of it since my system was performing normally, but I thought I would do a bit of research on it and what I found was a little bit concerning. From what I understood is that it affects the random generation of encryption keys, making them more predictable, I am assuming this includes encryption keys for everything, https traffic, password hashes, as well as local file encryption.

This did concern me, however a lot of the fixes suggest a BIOS update (the latest kernel update has not resolved it) I am a little anxious about doing a BIOS update when it has the potential to brick my motherboard (and I have never had the courage to run a BIOS update on any machine, even though I know I should).

I'm running Ubuntu 22.04 on a Ryzen 9 9900X3D and a Tomahawk B650 motherboard.

Is it something I should worry about?

Thanks

1. Environment & Hardware

Machine: Apple MacBook Pro 13-inch (Late 2013)

Network Controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter [14e4:43a0]

OS: Ubuntu 24.04 LTS (Clean install, LUKS encrypted LVM)

Kernel Version: 6.8.0-45-generic

2. Issue Summary No Wi-Fi connectivity post-installation. The proprietary Broadcom drivers (broadcom-sta-dkms / bcmwl-kernel-source) fail to compile via DKMS on Kernel 6.8 due to deprecated kernel API usage (specifically, the old init_timer function instead of the modern timer_setup).

3. Troubleshooting Steps Performed To rule out user error, missing dependencies, or broken package states, the following steps were executed using a USB tethered connection:

Clean State & Prerequisites: * Performed a full system update (apt update && apt upgrade -y) bringing the system to Kernel 6.8.0-45.

Installed required build tools: sudo apt install build-essential linux-headers-$(uname -r).

Package Cleanup: * Forced removal of previously failed GUI installations to break the apt broken-install loop using: sudo dpkg -P --force-all bcmwl-kernel-source broadcom-sta-dkms

Cleared cache and verified system integrity (apt clean, apt --fix-broken install).

Driver Installation Attempt: * Attempted to install the community-maintained package: sudo apt install broadcom-sta-dkms (also attempted bcmwl-kernel-source).

4. Result & Root Cause Analysis The DKMS build process fails consistently. Upon inspecting the make.log (/var/lib/dkms/bcmwl/.../build/make.log), the compilation aborts with the following critical error:

error: implicit declaration of function 'timer_setup'

Conclusion: The source code provided in the current broadcom-sta-dkms (and bcmwl-kernel-source) packages within the Ubuntu 24.04 noble repositories has not been patched to support Kernel 6.8. The proprietary Broadcom code still relies on the deprecated init_timer function, causing an inevitable compilation failure on modern kernels.

Request: Looking for information on whether a patched version of broadcom-sta-dkms for Kernel 6.8+ is planned for the 24.04 repositories, or if there is an officially recommended PPA/workaround for BCM4360 chips in the meantime, aside from manually patching the .c files locally.

In Ubuntu, configuration of settings such as the following can be done via console as mentioned in this question, including:

• Choice of compression algorithm
• Choice of the compression strength
• Enabling and disabling deduplication.

With which GUI based open source software, can one perform ZFS configurations such as the above?

I recently upgraded to 22.04LTS, and ever since the upgrade, my Dock-Icons have started to wiggle when there is an unread notification. Apparently, not all 22.04 users are experiencing this behavior, so I am unsure what could cause it. Does anyone have an idea how to stop this behaviour?

By default Ubuntu 21.10 (should be the same for 20.04) does generate temporary/privacy IPV6 addresses. I would like to disable this behavior in order to make my computer into a server, and to do so I would like to have an IPV6 address as stable as possible (notably to ease of process of configuring a DNS name without using DDNS, at least for the IPV6 address).

When looking at ip -6 address it looks like this:

    inet6 2a02:a03f:a0bb:abcd:ea4b:d152:592e:74da/64 scope global temporary dynamic 
       valid_lft 83659sec preferred_lft 69259sec
    inet6 2a02:a03f:a0bb:abcd:3c0d:e2ad:569e:2536/64 scope global dynamic mngtmpaddr noprefixroute 
       valid_lft 83659sec preferred_lft 69259sec

I want an autoconfigured permanent addresses like this (taken from a server in the same network, the address seem to have been generated using the modified EUI-64 algorithm):

    inet6 2a02:a03f:a0bb:abcd:211:32ff:fe59:76be/64 scope global dynamic 
       valid_lft 64840sec preferred_lft 50440sec

Please note I don't want to configure a static IPV6address!

That's why I ask this question today. Most Google searchs about this issue ends in nonsensical advice explaining how to configure a static IPV6 address. It's not the same thing than a permanent autoconfigured address. To generate those the OS must listen for the router to get the first 64 bits of the address and the complete the remaining bits with its MAC address.

I've looked at many similar questions but unfortunately the solutions didn't work for me. I have recently installed Ubuntu 18.04 and my speakers are not working nor are they are detected in the settings, they are actually listed as not available after running pacmd command. They are working fine on windows so the problem must be related to the compatibility with the driver in ubuntu, but I suppose there must be some settings to fix it. here ill pastebin what I get from the sinks list:

I want to restart the network service in Ubuntu 18.04. I tried /etc/init.d/networking restart but the command didn't come out as expected. Can someone help resolve my issue?

Even though I entered the right password to my machine I'm unable to login.

Issue I start my machine and for the first time I'm able to login with my password. Now I lock my machine or I suspend my laptop and try to login again. Then the Incorrect Password Issue appears.
Even though the password is correct I'm not able to login.

Temprorary Solution Whenever I switch the user and login with same user then I'm able to login or I restart the machine.

Has anybody, encountered this Issue? And are there any permanent solution?

The latest version of Ubuntu that works for me (in legacy mode) is 10.04 with the 2.6.32 kernel. Starting with 10.10 and 2.6.35 it won't work. I'm also able to boot Trinity Rescue Kit with the 2.6.37.1 kernel.

What are the differences between thee two releases that could prevent me from running it?

I had a 14.04 installation inside VirtualBox, and today I tried to update it to 16.04. It fails to boot after this. Selecting an older kernel version from the boot menu and/or recovery mode doesn't help. Do you have any ideas?

I want to count the number of lines in a file using wc -l but only output the number, without the following space and filename. Edit from comments: The filename may have numbers in it.

Currently if I do:

wc -l /path/to/file

On a file with 176 lines, the output is:

176 /path/to/file

This is within a bash script, and the resulting number will be assigned as the value of a variable.

I've been using Arch Linux with a patched kernel on my Surface Pro 3.
I switched to Ubuntu now and want to use the kernel that includes all the patches from Arch with Ubuntu. What is the best way to add the kernel? Can I simply copy the vmlinuz and initramfs and update-grub?

I copied the files and updated grub, which worked fine, but when I boot the new kernel I get a kernel panic: Unable to mount root root fs on unknown-block(0,0).

The kernel here was provided precompiled with with /usr and /lib as a .tar.gz archive. The kernel package I used does not provide that. It just contains the patches, so I can't just copy /usr and /lib from the archive.

I could copy them from my arch distribution running this kernel, but what specific directories would I have to copy, the whole /usr and /lib?

I just received an e-mail from Canonical warning me that the Ubuntu One service is going to shutdown. Is this real? Has anyone else got the same e-mail? Why is this happening?

Any information would be appreciated :S

Email:

Hi,

We are writing to you to notify you that we will be shutting down the Ubuntu One file services, effective 1 June 2014. This email gives information about the closure and what you should expect during the shutdown process.

As of today, it will no longer be possible to purchase storage or music from the Ubuntu One store. The Ubuntu One file services apps in the Ubuntu, Google, and Apple stores will be updated appropriately.

As always, your content belongs to you. You can simply download your files onto your PC or an external hard drive. While the service will stop as of 1 June, you will have an additional two months (until 31 July 2014) to collect all of your content. After that date, all remaining content will be deleted.

If you have an active annual subscription, the unused portion of your fees will be refunded. The refund amount will be calculated from today's announcement.

We know you have come to rely on Ubuntu One, and we apologise for the inconvenience this closure may cause. We've always been inspired by the support, feedback and enthusiasm of our users and want to thank you for the support you've shown for Ubuntu One. We hope that you'll continue to support us as together we bring a revolutionary experience to new devices.

The Ubuntu One team
