I have a laptop with Ubuntu 24.04.3 with LUKS encryption set up at the time of installation. I wanted to an "key-file in a USB drive" based unlock option in addition to entering the passphrase. To this end I followed the guide LUKS with USB unlock. Unfortunately I made a mistake somewhere and now my laptop does not boot and takes me to the intiranfs prompt.

How do I revert the changes I made to /etc/crypttab and other files using live-USB?

We have these new laptops from dell (max premium 16) and when we install the OS (jammy) on them WiFi/Bluetooth and camera is not working. A solution to fix WiFi/Bluetooth is to install a newer kernel using deb packages from ubuntu (https://kernel.ubuntu.com/mainline/v6.14.1). After installing this the touchpad stops working on the device.

I did try to unload and reload the module, but no luck

I am doing this to get logs:

sudo libinput debug-events --device /dev/input/event7

I don't get anything from touching it, but if I try to press the button I will get the following output randomly

On Ubuntu 24.04 with HAProxy 2.8.15-0ubuntu0.24.04.1 I use the default /etc/haproxy/haproxy.cfg file for my configuration. Many applications/services offer an option to place config files in a conf.d or appname.d directory.

As I understand it, HAProxy supports supplying the -f argument with a filename or dirname multiple times.

Who could add a /etc/haproxy/conf.d directory and utilize -f /etc/haproxy/conf.d (or /etc/haproxy/conf.d/*.cfg) in the haproxy.service systemd unit file by default? Is there a package maintainer that can improve this?

i have google-chrome-stable 142.0.7444.175-1 installed, and im trying to use manifests v2

when i open chromes from the shortcut, it runs a exec commands that i think is configured here /usr/share/applications/google-chrome.desktop there is three different configs [Desktop Entry], [Desktop Action new-window], [Desktop Action new-private-window]

the exec commands looks like this Exec=/usr/bin/google-chrome-stable %U for the [Desktop Entry], and similar for the other exec commands. i tried adding flags to the exec commands config, and i do not think that it worked, i didn't test a manifests, but i looked at the chrome://flags, and it didn't tell me about v2

these are the flags i tried to add, and it looked like this

Exec=/usr/bin/google-chrome-stable --enable-features=AllowLegacyMV2Extensions --disable-features=ExtensionManifestV2Unsupported,ExtensionManifestV2Disabled,ExtensionsManifestV3Only %U

well here is the entire file, well most of the file, this page is have problems understanding korean, so i have to remove that

and yeah im not sure what i should actually do so i can use manifest v2, or if i even should use manifest v2... i also want it to work from the desktop shortcut

it could be i actually want to edit /usr/bin/google-chrome-stable or it could be i just use firefoxs

thank you

I am dual booting W 11 and Ubuntu 24.04.3, all updates are current, on a Dell 7060 computer with a HP 2510 printer. Ubuntu is my main OS. My problem is the printer works in W 11 but has lost the print from printer in Ubuntu. Two days ago I could print anything in Ubuntu but yestertday the only option I had was Print to File. I have tried everything I can find but nothing works. Yesterday I uninstalled and reinstalled several times but still I only have print to file. Am I missing something that isn't being downloaded in HPLIP? Thanks for any advice.

I am attempting to dual boot Ubuntu onto my Lenovo Thinkpad P14 Gen 4 (AMD). Windows 11 will be my primary OS, but I wanted to experiment with dual boot, and wanted to do it this way as opposed to a VM.

I followed the tutorial at this link https://ubuntu.com/tutorials/install-ubuntu-desktop#3-create-a-bootable-usb-stick, and I am stuck on the F12 boot menu. The displayed drive shows the NVMe and USB HDD, however Ubuntu does not show up as a bootable OS.

To troubleshoot:

• I utilized both Rufus (see: https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#1-overview) and balenaEtcher software to create a bootable USB.

• Secure boot is off.

• This Thinkpad model has official support for Ubuntu 20.04 LTS per the Lenovo website.

I'm using Ubuntu Server 24.04.

I don't know exactly when this appeared first. Maybe after messing with ethtool. At least that's when I saw it on the laptop screen.

I have an external HDD with a permanent mount is /etc/fstab. Everything seems fine there.

I'd like to set up a Samba-share that is read-only for all devices in my LAN, except for a select few devices (based on IP address) that have write access. I explicitly want to keep the read/write access IP-based as this works best with my devices and network configuration.

I did not find a way to do this in a single share definition, so I tried a solution with two definitions for the same share (seen elsewhere as suggestion), see below. This does not work, however, as the first definition is overruled by the second. In the current order that means that no devices have access to the share except the few with write-access (that part works). When flipped, only the read-only share works and the devices that should have write-access get no access whatsoever.

How can I solve this issue?

I'm using a new laptop. It's the ASUS TUF a14 with Ryzen AI9 370hx + Nvidia GeForce RTX 4060.

After installing Ubuntu I faced a problem today where I was using the Firefox browser and was about to close it when everything froze. My keyboard wasn't working, neither was the touchpad. What could be the reason for this?

Before I faced a similar freeze up issue. When I was fractional scaling my screen to 150% using the display settings, the fractional scaling wouldn't work and the laptop froze after applying the settings.

What could be the issue, and can someone help me with this? Personally I suspect it's the graphics drivers or a hardware compatibility issue.

clevis tmp 2 successfully auto decrypts the disk and boots Ubuntu, however it did not start the docker services.

Prior to using clevis and tmp 2, docker container was able to start after reboot without login in to the OS.

But once I installed clevis, luks and TMP 2 and successfully auto decrypt the disk and booted to Ubuntu (without login in), it didn't start the docker container. I did a curl command to call a rest API from another PC and I got connection error.

Strangely, once I logged in to Ubuntu (without issuing any sudo command) , I was able to issue a curl command from another PC and I got a returned of JSON data. This shows that the docker service only starts once I have logged in. I'm using Ubuntu 24.04.

Could anybody tell me where did I go wrong? Thanks

After sound miraculously worked suddenly in 25.04, I have now the same problem like before in 25.10 (upgrade):

Sound shows just dummy output after boot. When loading a card profile manually ( pactl set-card-profile alsa_card.pci-0000_00_1f.3-platform-sof_sdw pro-audio ) there is no speaker in the sound test window.

Ubuntu 25.10, Linux ith-Yoga 6.17.0-7-generic,

inxi -A
Audio:
  Device-1: Intel Lunar Lake-M HD Audio driver: sof-audio-pci-intel-lnl
  API: ALSA v: k6.17.0-7-generic status: kernel-api
  Server-1: PipeWire v: 1.4.7 status: active

It might be a kernel problem (Regression in kernel 6.17.8)

Suddenly sound works but no speakers in test.

In Ubuntu 25.10 GNOME / Wayland (physical machine) it seems that it is not possible to change the cursor style for all applications.

When I try to change the cursor style from gnome-tweaks → Appearance → Styles → Cursor to something else than Adwaita (default) all GNOME applications and most non-GNOME applications like Thunar, VirtualBox, Remmina, Google Chrome, MS Edge, etc. still continue to use the default style.

The style change seems to have effect only on some applications like Firefox, Thunderbird, Geany, or LibreOffice; but not in general.

There are some similar reports that suggest logging out and re-logging into the desktop session, but this makes no difference in my case.

_{Note: This problem may be related to the problem of an Ubuntu 25.10 GNOME / Wayland VirtualBox guest where the mouse pointer does not change when hovering over window borders, so making resizing windows difficult.}

In Ubuntu 24.04.3 I have in the settings the Automatic Date & Time and Automatic Timezone. I can change manually via GUI, configure the continents and cities with sudo dpkg-reconfigure tzdata but I can't make it be automatic and since I travel quite a lot It kind of bothers me not having that automatic change and having to change it everytime.
(Don't know if it matters but I'm using a dual boot system where windows is really just a fail safe)

This is the timedatectl output while I'm South Africa and still displays Portugal's time/zone

timedatectl

Any tips or is this a known issue?

On another post I accidentally wrote I had version 20.04. It is not so and I have 24.04. My mistake. The post got closed.

A few days ago I decided to work to bring an old laptop I have into a movie server. It worked great until today when a speed test reported 100mb/s of download. It should be 1000mb/s as it was the days before. The cable is correct. I searched forums and some guy recommend to paste this ethtool command:

ethtool -s (network-id) speed 1000 duplex full autoneg off

What it only did was to immediately disconnect me from SSH and not let me connect again. It messed up a lot of things that some I was able to fix it by myself.

I have 3 problems:

1. The boot process is suddenly very long, about 4 minutes. It was about a minute before.

2. There seems to be a couple problems at the login screen. See attached: https://imgur.com/a/QWgbMAY

3. The problem with the network speed continues. I've discovered that it has normal 1 GB speeds and after some time it caps at exactly 100mbs. I speculate it's some power-saving setting. I've already edited "HandleLidSwitch" on logind.conf.

After years I had problem with the AMD driver. Discord crashed while I was sharing my webcam. I tried to update or change to the Ubuntu driver, but I am stuck.

Could not find both graphics and present queues

glxgears is working, but makes a noise on the speaker (tested this with the old driver, was not so intense. I'm not sure if it's related.)

At the moment the aim is to be able to use Discord, Steam, and Lutris again. The main window does not launch, just frees the display until I close it.

I tried to uninstall all packages, remove the PPAs that I do not need, and reboot and update and install the packages for AMD support, but that did not work too well. What have I missed? I would like to continue using Ubuntu until Ubuntu 26.04 before doing a clean install.

Edit: The Ask output, I checked the motherboard GPU, should not be configured to be used, as far as I can tell. @user7215 or what are you looking for?

I've got what I think is a noob problem. After several hours of trial and error I've managed to add one folder to Samba which is now accessible in Windows after entering credentials to Samba server. Then, I decided to add more folders to be shared via Samba.

Unfortunately, even though I can see the folders after connecting to Samba, I can only access the very first folder I added (i.e. folder named "sharing").

I've tried to replicate the steps that led me to successfully set up the first folder (using these guides: https://www.antixforum.com/forums/topic/how-to-create-a-samba-shared-folder-your-private-network/ and https://phoenixnap.com/kb/ubuntu-samba) but so far have been unsucessful.

What am I doing wrong? Why is only one folder accessible, while others aren't?

Below you'll find my smb.conf file. The "sharing" folder is the only one that is accessible in Windows.

[global]
server string = samba_server
workgroup = WORKGROUP
security = user
map to guest = Bad User
name resolve order = bcast host
ntlm auth = yes
usershare allow guests = yes

[sharing]
path = /home/sharing
force user = smbuser
force group = smbgroup
create mask = 0664
force create mode = 0664
directory mask = 0775
force directory mode = 0775
public = yes
writable = yes

[Windows]
path = /home/michal/Windows
force user = smbuser
force group = smbgroup
create mask = 0664
force create mode = 0664
directory mask = 0775
force directory mode = 0775
public = yes
writable = yes

[One Touch]
path = "/media/michal/One Touch"
force user = smbuser
force group = smbgroup
create mask = 0664
force create mode = 0664
directory mask = 0775
force directory mode = 0775
public = yes
writable = yes

[Seagate]
path = /media/michal/Seagate
force user = smbuser
force group = smbgroup
create mask = 0664
force create mode = 0664
directory mask = 0775
force directory mode = 0775
public = yes
writable = yes

FIX:

After trial and error, I've changed the above to the following, and the folders and files are now accessible in Windows. Unfortunately, it seems that I had to let go of some security, as the files are accessible without a password now.

[global]
server string = FILESERVER
workgroup = WORKGROUP
security = user
dns proxy = no

[OneTouch]
path = /media/michal/One Touch
valid users = michal
writable = yes
browseable = yes
read only = no
guest ok = no

[Seagate]
path = /media/michal/Seagate
valid users = michal
writable = yes
browseable = yes
read only = no
guest ok = no

I have THIS BUG only in one project, that's driving me crazy and I don't know what else to do to fix it:

After uploading pending changes to GitHub, the bug persists:

But in the other projects looks good:

The bug in question only appears here and it displays that >R> which I'm not sure which glyph it refers to.

To give you some context:

• My operating system is Ubuntu 24.04.3 LTS

• When I run it echo "\ue0b0 \u00b1 \ue0a0 \u27a6 \u2718 \u26a1 \u2699" it shows me this:

  

• In the terminal preferences I have this:

  

• I've tried different fonts that I downloaded from here: https://github.com/powerline/fonts

  git clone https://github.com/powerline/fonts.git
  cd fonts 
  ./install.sh
  sudo fc-cache -fv  //to refresh the cache without having to restart
  

• As you can see, they appear for me. I've tried several and none of them fix the bug.

  

Any ideas on how to fix it? Thanks in advance 😊

I've already run sudo apt update and sudo apt upgrade as well as sudo apt install libc6, but it says it's the latest version. It's running on Ubuntu 22.04.5 LTS.

Hardware:

• CPU: Intel Core Ultra 9 285K (Arrow Lake)
• Motherboard: Supermicro X14SAZ-F (BIOS 1.0, dated 04/17/2025)

Problem: All Ubuntu installer ISOs freeze immediately after GRUB while only printing 1 (or 2 depending on TPM) lines:

EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Measured initrd data into PCR 9

Complete lockup - no keyboard, no output, inoperative numlock, despite testing with earlyprintk.

AlmaLinux 10 (kernel 6.12.0) boots perfectly from USB installer, so the Hardware and Bios are fine.

Tested (all failed):

• Ubuntu 22.04.5, 24.04.3 (standard + HWE 6.14), 25.10
• Boot parameters tried:
  • nomodeset
  • nomodeset acpi=off
  • nomodeset noapic acpi=off
  • nomodeset acpi=off noapic nolapic nosmp
  • nomodeset intel_iommu=off iommu=off
  • nomodeset debug ignore_loglevel earlyprintk=vga,keep (no extra output)
  • nomodeset earlyprintk=efifb debug (no extra output)
  • gfxpayload=text
  • Various video= parameters
  • dis_ucode_ldr
• Multiple displays, TPM on/off

Any ideas welcome.

I couldn't find any questions with solutions on this site or on Google for the following info message in the syslog

Feb  3 21:15:17 XXXXX ModemManager[860]: <info>  [base-manager] couldn't check support for device '/sys/devices/pci0000:00/0000:00:1f.6': not supported by any plugin
Feb  3 21:15:17 XXXXX ModemManager[860]: <info>  [base-manager] couldn't check support for device '/sys/devices/pci0000:00/0000:00:1c.2/0000:02:00.0': not supported by any plugin

Ubuntu version: "Ubuntu 22.04.3 LTS"

What I'm trying to do: Switch Linux server (running on Dell Latitude laptop) from Google Nest to Nokia Wifi 6 router (model XS-2426X-A).

I may not be making the correct assumption that it's the support message that is the cause of the internet connectivity issues. I was able to make the same switch a few days ago on a Ubuntu 20.04 server, Dell Inspiron, running these same steps:

1. Edit the netplan yaml to point to the new router ssid
2. Run sudo netplan try

On the older device that succeeded, the ModemManager info message never showed up.

After running these steps on the server with the newer OS, it is visible in the device list of the Nokia wifi app. I started wondering if it's a firewall issue because of this message in the syslog

kernel: [1021318.200175] [UFW BLOCK] IN=wlp2s0 OUT= MAC=xxxx SRC=xxxxxx DST=xxxxx LEN=112 TC=0 HOPLIMIT=64 FLOWLBL=601761 PROTO=ICMPv6 TYPE=1 CODE=3 [SRC=xxxxxx DST=xxxxx LEN=64 TC=0 HOPLIMIT=254 FLOWLBL=0 PROTO=ICMPv6 TYPE=136 CODE=0 ]

But then a similar UFW block message showed up in the syslog of the older server after the switch, and it persists today, with the application there running fine and communicating with the internet.

Should I look for plugins to be installed for this Nokia device, or is it something else that's keeping the application on the newer machine from talking to the internet?

I execute the command:

sudo do-release-upgrade

and I get this output:

I am happy that grep does support Perl Compatible Regular Expressions with the -P option.

Is there a reason why the tool sed does not have this feature?

Is there any tools/ commands to extract a mht file to its component html, js, css and other resource files on Ubuntu 16.04 ? One of my bank'suse this format and though I can open it in chrome was wanted to convert it to html.

Save as saves the html but the styling does not stay.

I'm trying to migrate to my new NVMe Samsung 950 pro.

chroot /mnt/boot-sav/nvme0n1p3 update-grub
grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.

Process:

• Copied/pasted via Gparted (lastest gparted live-cd)
• Ran boot-repair (with 15.10 ubuntu desktop)
• failed on update-grub

http://paste.ubuntu.com/13244403/

Old drive had:

• sda1 fat32 EFI
• sda2 ntfs
• unallocated (had to shrink a small amount for new drive)
• sda3 ext4
• sda4 linux-swap

My first guess is that I'm no longer using an sd, but an nvm prefixed device.

Any thoughts/help is appreciated.

When I look in /boot/grub I do NOT have a device.map. I read that I don't need one for grub2, but I generated one, ran update-grub and ran into the same message as above.

I attempt to reboot anyway, and my EFI only shows a Windows Boot Manager as a bootable item, for which it lands on a windows recovery screen. The Ubuntu partition isn't listed as a bootable drive in EFI.

I am experiencing problems when trying to read DVD-Rs or DVD+Rs recorded by different TV DVD Recorders. Usually the problem is that when I try to manually Mount the dvd with the udf option (with auto option same output):

I think this is not a problem with my hardware because on the same machine W7 (I have dual boot) can read the disks and extract the files (most of those disks must then be decrypted since they are CPRM encoded coming from a Japanese DVD recorder). However the drive is an ATAPI DVD A DH16ABSH. I already tried switching to IDE mode from AHCI (bios setting) but nothing worked.

I must add any other disk (including DATA DVD and original Video DVDs) is correctly mounted. Is there a way to Mount these particular disks? Is this a known bug (I have found some short references of people having the same problem online, but no solutions like in this discussion)?

Here is what I can exctract from one of those disks by Nero, KB, and a Windows util I downloaded:

On ubuntu server here and I'm trying to unpack 300M image files from a compressed file format using Java.

My unpack rate is 0.5Mbytes/sec, abysmal (34 days to unpack 1.5TB at this rate).

I'm trying to figure out why, and the only oddity I notice is that updatedb.mlocate is always working when I'm doing the unpack process. I want to turn it off to see if it's getting in the way, but I don't understand much about what it is.

I am about to set up box to basically be a file server. I plan on having multiple drives in the box, and would like to set them all up so that they appear to be a single drive. So I could essentially have it mounted at say /media and not really care which drive gets used. I am not sure what the correct terminology for doing this is, so my Google fu is useless in this situation.

So how do I set up multiple hard drives to appear as one single drive?
