Ubuntu 24.04.4 LTS

Linux 6.17.0-22generic

X86-64

Ethernet controller RTL8125, Network controller Fastconnect 7800

Command line input "ping -c 4 8.8.8.8" gives "Network is unreachable" but Command line input "nmcli device show" gives "lo, loopback, 00:00:00:00:00:00, 65536, 100 (connected externally), lo, /org/freedesktop/NetworkManager/ActiveConnection/1, 127.0.0.1/8, - -, ::1/128, - -"

It's not seeing the cabled modem or WiFi, and cable hotspot too. Headphones are also not working, and it seems to be ignoring the graphics card. Are there any other options I can use to try to fix this, so I can try to "un-update" it?

It was working ok before, although RSSEED32 has been broken for a few months, so the corresponding Cruid? had been disabled. I believe it was some kind of workaround for an unfixable physical security flaw.

I have run out of ideas with this one.
I have found similar questions, but the suggested methods didn't work for me.

Basically, every time I boot I get a lot of these errors. dmesg shows that this occurs several times before the system gives up with usb 3-2-port3: unable to enumerate USB device.

I have searched a lot, but nothing seems to be working. Here's things I have done/noticed:

• Cleaning, unplugging everything, restarting, removing battery, ...

• lsusb -t doesn't list anything with bus 3 port 2.3

• I think the faulty device is the fingerprint reader, since it never worked properly and now I noticed that the laptop doesn't even detect it anymore (and I don't see any device resembling it when running lsusb)

• I can't lock it from the bios. I tried to lock other devices just to try, like the entire touchpad (on which the fingerprint reader sits), but the error persists.

• I tried writing a udev rule to unauthorize the device, but it didn't work.

I don't really know what to try anymore, but the problem is really annoying, since it occurs every time I "unsuspend" or boot my system, and sometimes shutdown and suspend freeze for some time before succeeding, and I think it's because of this.

Thank you in advance for your help!

I'm on Ubuntu 24.04 LTS. I sometimes edit large numbers of audio clips according to some set rules, and I have a macro set up in Audacity that does exactly what I want. Unfortunately, if I run this macro on 20-50 files or so, Audacity's dialog boxes pop up and seize focus every time one of the files is processed with the macro. This means I basically need to stop using my computer while it's running, since I can't do anything else for more than a second or three at a time before Audacity interrupts me. Depending on the number and size of the files, this can take 5-15 minutes at a time.

I've tried a variety of ways to mess with focus raising and focus stealing settings to make Audacity work quietly in the background, including using CompizConfig Settings Manager to modify the Focus & Raise Behavior, and running Audacity in a different workspace to my main workspace. I also tried a couple of other one-off suggestions I found scattered around the web as well that I can't remember. All to no avail.

I don't really mind how I do it and what levers I have to pull. I just want a way to let Audacity run its macros without interrupting anything else I'm doing on the computer. Is there some way to achieve this?

24.04 LTS: Launching the ubuntu guide (blue question mark icon), shows a working 'hand' pointer for a few seconds then freezes (no mouse or keyboard) requiring a hard reset. Never used the guide before so it may have always been broken.

Is there a way to identify all the changes that have been made to a specific install of 24.04? If I wanted to go back to a point before I installed package x and its dependancies, I would at least need to list all packages by date of install.

Running Ubuntu 25.10 and during a recent update my WiFi strength indicator dropped to one bar even though signal strength is strong. How can I fix? My WiFi adapter is an Intel AX210NGW 6E however the issue started with my original adapter that came in a Dell Inspiron 15 notebook computer. My actual signal strength is -49 dBm:

We have a payment system currently running windows 10 on Raspberry Pi's. A Linux platform is now in development instead.

Right now we can access those RPI's via Teamviewer over a MiniPC or an Intel Stick in each location.

Making to move to Linux, it makes sense to transform those MiniPC's to Ubuntu Server (jumphost) and connect to the PI's through SSH.

I have installed Ubuntu Server 24.04 on one of them.

Now I just need to get a connection through on the LAN adapter.

Got a script on how-to from the developers off our payment system.

Netplan for this.

Changing parameters to this.

And that's where the guide sort of ends.

When I save it, what should I call it?

It suggests the same name as when I opened Netplan, but that can't be right.

I asked Gemini, but that's just as unclear as the guide.

I installed Ubuntu 24.04 on a Mac with Intel chips. But when the first screen appeared where I would select the language, the screen froze, no movement of arrow keys or mouse was possible.

I was trying to use openbox login in session at startup (the light bluescreen ofLubuntu 22.04 where I can choice Lubuntu or lxqt or OpenBox (I am specking about this openbox of start up I mean session login, and not about window manager of Lubuntu session).

I use Lubuntu 22.04 with2 GB RAM so I was thinking that open box would be an interesting alternative..

Lubuntu has openbox, I don't need to download openbox

I was trying because I failed to use openbox: the terminal from menu popup do nothing. and the pop up menu only work gnome charmap and tint2

I installed (I saw vids on yout...) obmenu tint2 and terminals: Terminator, xterm an lxterminal from my distro (now 5 was uninstalled) because never I could use terminal ...

What is the terminal that openbox use?

Thank you and Regards!

After installing Ubuntu my laptop keyboard is not working some button are not working and my touch pad is not working too and my laptop is Dell Ubuntu window 10 server 25.10

I'm not sure what happened, but I am running 4 Dell Optiplex machines and they all have the same problems going back several weeks. General slowness, choppyness, high CPU, slow load times on web pages and so on. The telltale sign is choppy mouse that freezes momentarily when a tooltip pops over the GUI or when the machine is processing.

All machines are from the Dell Optiplex series. They all have integrated, Intel video cards. They're all running 24.04. I've tried rolling back the kernel, switching from Wayland to Xorg, and disabling Gnome extensions. I have not read of others having this specific problem but it can't be a coincidence if it happened to all my machines at the same time. Any ideas how to fix this?

Ubuntu 22.04 LTS. In Settings, the Printers dialog has recently started to challenge me with a login to unlock it every time I touch it. Same for its Additional Printer Settings. I have not found where to turn it off.

Is it in Gnome? Cups? PolicyKit?

I was editing a file that I assume was originally created with MS Office power point. When I was done with my edits and saved the file, LibreOffice added blue dots and a box with text "Responsible: Text" on every page. How do I remove them?

I had an identical machine HP 14s dq3xxx with absolutely no problem running 24.04.4
Except one coffee spill too many and it died.

New Laptop came with Win 11, turned off Bit Locker, installed 24.04.4.
On installation I turned Windows Bitlocker off. Just like last time.
Only the hard drive has gone, the only drive is described as a "card reader".
Has anyone got any thoughts on what I've done?

Thanks. Paul

I am about 3-4 weeks new to Ubuntu, downloading it in a bid to not install Windows 11, and for those weeks I've been trying my hardest to get my Steam games working on this device, to no avail.

Some games do work. I was able to get PEAK working on my computer after a LOT of setup, and single player games/really old point and clicks (e.g. Dave the Diver, Sam and Max Hit the Road, IHNMAIMS) work perfectly (though this could just be because of how simplistic they are).

Games such as Deadlock, Marvel Rivals, and The Outlast Trials, more high-fidelity games with a high amount of multiplayer however don't boot up. The best I've gotten is Deadlock, which I've been able to get the launch screen up until it crashes. Unfortunately all the answers I've seen on this website are either not working, or are simply too complex for my newbie brain to comprehend. I have gamemode installed and configured, GeProton is installed and applied to all desired games, ProtonTricks is installed, though I have no idea idea how to use it, and my Driver package is nvidia-driver-535.

Here is the last terminal log I recorded with Deadlock, gained by running Steam through Terminal. If I had to guess what the problem was, it would be the system is not recognizing libgamemode.so, despite it being on the device.

Please help me with this. I'm at my wits end, am not going back to Windows for the life of me, and I not really welcome to the idea of booting another OS such as Arch and drafting all my files to that system just to have a better chance. It's already been a pain in the ass just to get Ubuntu working.

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?

None of the comments were in any form helpful. I mentioned it clearly the problem is the Broadcom wireless chip for which I'm not able to find a working driver. Of course the behaviour of the Ubuntu installation program is not helpful at all. Knowing, not having a valid driver for the wireless, I connected the LAN-cable, to install this way. Big Error! Choosing Internet available, true by LAN-cable, the Installation program crashed without any valid message, and in a very ugly none irrecuperable way! Very bad bug! On selection no Internet for the moment, the installation was possible, and Oh wonder, On connecting the LAN-cable even the Internet was available! And No, wireless and Bluetooth still doesn't work. But for this problem I put a new question. But first, I'll install windows 10 again, just to verify if this ugly Broadcom chip is working as it should! Question closed!

The HP x2 Elite gen 8 laptop was designed for Windows, and Bang & Olufsen worked on improving the sound for it. Ubuntu 25.10 is installed. Apparently they made some changes to the design (maybe the chip; by the way, some Realtek worked with Windows 11). Currently the sound device only works in mono mode.

Audio by Bang & Olufsen. 2 Premium stereo speakers (74dB). Realtek ALC3292 Audio codec and 2 NXP TFA9894 discrete amplifiers. 3 Integrated microphones including one world-facing. I'd like to fix this if possible.

I am contacting you in order to receive help to repair my Ubuntu OS. Two weeks ago I tried to install a protection against viruses and other cyber threats on my Ubuntu 22.04 system, but I did something wrong, which resulted in the APP Center being completely deleted and therefore, the applications for Mozilla Firefox, Chromium, Music Player as well as Clementine, among other applications, being uninstalled. To try to solve the problem, I upgraded from Ubuntu 22.04 to Ubuntu 24.04, thinking that all the packages would be reinstalled and everything would go back to normal. But that was not the case, now everything remains the same and the software updater does not work when installing updates, warning me that: The package system is broken. I would greatly appreciate your help in this regard. My laptop is a Lenovo G50-70 and the OS is Ubuntu 24.04.

I have a strange thing I cannot figure out. Have checked manpages, etc. So hoping someone else had the same issue.

To convert from a normal .list file to a .sources file, as is now used in Ubuntu 24.04 LTS, I will use tor as an example:

Old way (tor.list):

deb [arch=amd64> signed-by=/usr/share/keyrings/tor-archive-keyring.gpg] https://deb.torproject.org/torproject.org jammy main
deb-src [arch=amd64> signed-by=/usr/share/keyrings/tor-archive-keyring.gpg] https://deb.torproject.org/torproject.org jammy main

New Way (tor.sources):

Types: deb
URIs: https://deb.torproject.org/torproject.org
Suites: jammy
Components: main
Signed-By: /usr/share/keyrings/tor-archive-keyring.gpg

The problem I have is this:

In the tor.sources, from what I can find, there is no way to specify the arch / architecture. I've tried arch, architecture, system, etc. Nothing works.

This is the error I get:

N: Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'https://deb.torproject.org/torproject.org jammy InRelease' doesn't support architecture 'i386'

I know this is a cosmetic thing and it mostly just effects logs, etc. But, simply finding a way to specify the arch would fix this entirely.

Anyone has any ideas?

• Note: in this example jammy is used, because tor does not yet have noble and jammy does actually work on noble for most repos! This is not the cause of this issue and is not going to solve it :)

• RESPONSE TO BEING DUPLICATE (Skipping acquire of configured file 'main/binary-i386/Packages' as repository 'xxx' doesn't support architecture 'i386') ... That is for Ubuntu 22.04 and discusses ".list" files. ENTIRELY DIFFERENT FORMAT AND NOT AT ALL SAME AS ".sources" files.

On my Ubuntu 20.04 machine, when I run:

mkdir -p /home/parent/{child1,child2}

These folders get created in /home.

• parent
• parent/child1
• parent/child2

However, when I try to run this in a python script using

bashCommand = "mkdir -p /home/parent/{child1,child2}"
# print(bashCommand)
subprocess.run(bashCommand.split(), capture_output=True)

I end up having these folders in my /home directory instead.

• parent
• parent/{child1,child2}

How can I fix this?

I have now three hard disks in my desktop. A Samsung SSD that boots Win7, a Toshiba HDD which is not bootable, and yesterday I added a Crucial SSD which boots Ubuntu 21.04.

If I now simply start my computer, Linux on the Crucial will boot..

If at startup I press F11 this allows to choose between these three and surprisingly, a non-existing fourth named "Ubuntu"(?). If I click on the Samsung then Windows will boot, if I click on the Crucial (or Ubuntu) Ubuntu will boot. As you can see on the left of the two pictures:

The right picture shows what I get when press F2, the boot order setting at the ASRock Motherboard, while booting, I only get to "choose" between the identical Crucial and Ubuntu...

I want the Samsung to boot Win7 as default. From what I have heard, I have to do this in Ubuntu, and I know absolutely nothing about it. How do I make this change?

It was suggested to use grub-customizer for this, but as the picture shows, it does not even see the Samsung disk with the Windows.

My Win7 is not an UEFI, it is a legacy installation. Could that be the reason?

I downloaded Ubuntu 18.04.3 LTS and put it on a USB flash drive. Rebooted the MacBook into recovery mode (Command+R) and enabled booting of external media and unsigned operating systems. Rebooted again holding Option and selected to boot from my USB drive ("EFI Boot" in the boot menu).

The Ubuntu boot menu (GNU GRUB version 2.02) shows up, but no matter what I choose in the menu, it just goes into a kernel panic with a lot of ACPI related errors, including this one:

As a classroom for learning Unix/Linux, I'm using Microsoft's Ubuntu App in Windows 10. I want to run:

gedit somefile.txt

But I get the following:

Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused
(gedit:27829): Gtk-WARNING **: cannot open display: :0.0

None of the following solutions have worked:

1. As per this page I tried gksu gedit and just get the final line of the above error, and I tried sudo nano and can edit the file (but isn't really a solution as I want to use gedit).

2. As per @WinEunuuchs2Unix's solution I downloaded VcXsrv, added export DISPLAY=localhost:0.0 to ~/.bashrc, installed ubuntu-desktop and yad and still get my original error when trying to open gedit.

3. As per this page I installed Xming and vim-gtk and tried gvim instead of gedit and get:

   E233: cannot open display

4. I followed this PC world tutorial probem-free up until dbus-launch --exit-with-session ~/.xsession, which gives me:

   /usr/bin/startxfce4: X server already running on display :0.0 xrdb: Connection refused xrdb: Can't open display ':0.0' xfce4-session: Cannot open display: . Type 'xfce4-session --help' for usage.

And now I don't know what else to try, so I'd love some help! I also hope this is a good question and apologize if I'm making a typical newbie error.

What is the best practices to leave this kind of file? I dont want to leave it on /Downloads folder

I have been using Rhythmbox on Ubuntu 14.04 to play music from my iPhone for a while now. Sometimes I get the annoying "initialize your iPhone" dialog box, but I just cancel it, unmount and reconnect my phone, and the problem is solved.

Background: Getting things to work with iOS 10

Recently, I updated to iOS 10, and mounting the iPhone stopped working. I somehow fixed this by cloning libplist, libimobiledevice, libusbmuxd, usbmuxd, and ifuse [note: ifuse doesn't seem necessary if you use gvfs], checking out the master branch in each repo, and installing via

./autogen.sh
make
sudo checkinstall

so that the package versions and dependencies could be managed via dpkg.

For libimobiledevice I also did ./autogen.sh --disable-openssl so that I'd use GnuTLS instead.

Because I had originally installed most of these packages via apt-get, I installed libplist as the dpkg package libplist1, libimobiledevice as libimobiledevice4, and libusbmuxd as libusbmuxd2. I also did echo /usr/local/lib > /etc/ld.so.conf.d/libimobiledevice-libs.conf and some extra symlinking when programs complained that /usr/lib/libimobiledevice.so.4 and such were missing.

Getting gvfs to work

ifuse will now successfully mount the iPhone, but my actual goal is to get gvfs to detect and mount the phone so that it'll work with Rhythmbox. I may have needed to do additional symlinking to even get the gvfs-related programs to run, I forget.

If I naively try to plug in my phone at this point, I (with high probability) get the error message Message did not receive a reply (timeout by message bus). I have to run /usr/lib/gvfs-gvfs-afc-volume-monitor 3+ times until I get lucky enough for the phone to mount; this seems very wrong.

Running sudo usbmuxd -f -v spams me with messages like

New client on fd 19
Client 19 connection closed
Disconnecting client fd 19

over and over, plus an instance of Receive from client fd 19 failed: Connection reset by peer and Connection reset by device 4 (3->62078). Basically, I have no idea why mounting only works intermittently. Things seem to work more often when I run usbmuxd in the foreground with -f, but that may just be confirmation bias.

When I finally do get the phone to mount, Rhythmbox will start and display the "initialize your iPhone" dialog, with two problems: (1) it hangs for a long time while loading this dialog (trying to connect with phone, possibly, or maybe Rhythmbox is just ultra slow?) and (2) if I hit "cancel," I can no longer see the phone mounted on Rhythmbox. Before, after cancelling once, I could unmount and reconnect my phone and the dialog would no longer pop up, but this method is far less reliable because I can't reliably mount my phone! So after all this...

Questions

1. Is there a "more correct" way that I should have gone about the installations from source?
2. How do I get gvfs to reliably mount my phone on the first try?
3. Should I stop using gvfs/rhythmbox and start using ifuse+something else?

I was trying to delete a folder and messed up. I'm getting this error while I'm trying to use sudo:

sudo: error while loading shared libraries: libsudo_util.so.0: cannot open shared object file: No such file or directory

How can I fix this?

I would like to find a utility that can find the hidden URL to eg this streaming radio

so I can use that in mocp (music on console player). URLsnooper is there for windows, but I can't find an alternative for Linux.

I want to be able to do one or all of the followings:

• Talk to my computer and be heard over a network (Crazy O.o)
• Live Video Streaming (Watch a Video and share over network)
• Live Audio streaming (Listen to song and share over network)

How do I limit the updates that are installed to those from a specific set of repositories? Is this at all possible?

Before i try to install a program in ubuntu, where can i see how much disk space the package including the needed dependency packages will need. Perhaps a commandline way?
