I am in the process of upgrading from Ubuntu 22.04 to Ubuntu 24.04, and I'm having a problem with recovering some 10 plus years of Firefox bookmarks. The last few months of 22.04 Firefox became prone to freezing so I would have to reboot to clear it. In frustration I tried Chromium, but found it only slightly less prone to freezing, so I decided to upgrade to Ubuntu 24.04 to see if it would be any better.

That's when I discovered that Chromium had without any notice to me converted all my HTML Firefox bookmarks to JSON formatted Chromium bookmarks.

Is there:

1. A way to turn JSON back into HTML
2. A way to get Firefox to accept JSON bookmarks
3. Do I have to accept the fact that I am permanently cursed with Chromium?

I am trying to connect to my Ubuntu 25.10 running on a Dell XPS15 9550 using Windows 11 (24H2) RDP. I cannot make it work. I have spent many, many hours working both with Gemini and Claude, but neither of them have succeeded making it work. Does anyone know how to do this?

So I've bought a JBL Quantum 100M2

I've tested it on windows and It works flawlesly when I select the option "Headset" when I plug it. (Illustation bellow)

⬆️ Realtek input type select selection.

When I try to do the same thing in Ubuntu 25.10 there's no option for selecting the mic from my headset, and the default mic selected (family 17h/19h/1ah HD Audio Controller), only outputs white noise.

I've tried adding these headset options, individually, to the alsa config in /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=headset-mode
options snd-hda-intel model=alc287-acer
options snd-hda-intel model=dell-headset-multi

I've also tried disabling fast boot in combination with the configs above, but with no success.

I have no experience at all with this type of configuration, is there an easy solution for this? Is this a known bug?

Additional info:

• Motherboard model: Nitro AN515-46
• Using pulseaudio 1.4.7
• I've tried using Analog stereo Duplex and Pro audio. Neither of those worked

I just installed Ubuntu for the first time on my MacBook Pro 2023, and I didn't have the option to connect to wifi at all. I searched here and tried everything, but nothing worked. Here's my terminal output with the Broadcom stuff.

01:00.0 Network controller [0280]: Broadcam Inc. And subsidiaries Device [14e4:4434] (rev 04)

And then right below it:

I run Xubuntu version 25.10 with Nvidia driver enabled in system settings. After installing the latest updates the screen shows some flickering. When I try to change to Xorg X open source driver on next reboot I have a black screen. By entering into recovery console I can sort of 'purge' the nvidia settings but still I cannot enable the open source driver without black screen. What is going wrong here?

Thanks for any advice on resolving this issue.

I am a long-time Ubuntu user, and have been using this laptop with Ubuntu as the only OS since I bought it six years ago. I am currently running Ubuntu 25.10. The laptop has always booted up in around a minute or so. Recently I added a second screen for my coding work so I can ssh to Arduinos, ESP32s and my new toy, a Jetson Orin Nano. At first booting was as before, but I noticed that sometimes the Ubuntu symbol appeared on the second screen but without the login box, so I had no way of logging in.

I held down the power switch (I should have ran Alt-Print-reisub, but I forgot about that until now), and then powered it back on. This time both screens remained blank. I powered down again by holding down the power switch (bad I know) removed the second screen and powered back up. Nothing was happening on the screen, but the HDD LED was flashing now and then and sometimes the fan started up, but the screen remained blank for several minutes.

After a while I left the laptop to go and do something else. When I returned the login screen was there and everything worked as normal. I intend to shutdown properly now without the second screen connected to see if I can logon in a reasonable time frame next time, but I thought I'd ask if anyone here has had experienced this first.

Recently, I have been noticing that for Ubuntu 24.04.4, whenever the computer resumes from an automatic suspend mode, it actually did not suspend and resume. Rather, the computer logout and I was required to login again. I say this because a resume screen does not appear but the GDM login screen appears. Also, after login, I have to restart all my apps again.

Below are some info I can gather about the system, GPU and suspend log related to the suspend and resume event.

The system used to be able to suspend and resume.

How to fix this issue?

Update: I noticed this gdm log for the Automatic Suspend event. These are its final few lines.

I use fzf to searched for error and session at the timestamp of the automatic suspend event, and found a fatal server error.

I upgraded from Ubuntu server 24.04 lts to 25.10 and after that I can't connect to Tor (though my Snowflake proxy which I run is up and no issues), login manager having issues in boot, half of sites are not loading (Not a problem with internet I checked) and rdr2 installer isn't working. Weird thing is in logs, there doesn't seem to be any issue and this is like a pause/hang even when my specs are good enough (i5-13450 hx, rtx 4050, 24+512). Before upgrade, there wasn't any issue, and system was stable and working. But suddenly after upgrade, half of my system isn't working. This is my first upgrade, so maybe I think I missed something. Any advice on what I should do? Thanks

It all started today. Whenever I try to update anything using the sudo command the terminal throws an error. See the error as attached.

I already tried removing and purging these two specific packages, but I can't reinstall them at all or else it gives the same error. I am new to Ubuntu, so help me in ways that don't wreck my system. I found information on some other forum about deleting the kernel altogether, but I don't know how to boot from an old kernel.

Xubuntu 25.10 > do-release-upgrade -d > 26.04 beta

The firmware is now split by vendor. One would expect only the x86 firmware to be included. But I also see e.g. a /lib/firmware/arm directory. None of the "what package provides" methods I found via google finds the providing package. Are these files left-overs from the previous monolithic firmware package? Can I safely purge those arm firmware files?

Also it is not unthinkable that a vendor provides x86 and arm firmware. How would that situation be handled?

I rent two virtual servers at Strato. A few days ago I upgrade both machines via do-release-upgrade to Ubuntu 24.04 coming from 22.04. On one machine everything works fine, on the other one I have DNS name resolution problems. I found this question: DNS at systemd's 127.0.0.53 is ignoring some lookups and tried following the answer to that. I also had a look at https://wiki.ubuntuusers.de/systemd/systemd-resolved/

As far as I could say, the systemd-resolved looked like it should. /etc/resolv.conf was a symlink to /run/systemd/resolve/stub-resolv.conf in /etc/systemd/resolved.conf I had the same content as on the other server where it works fine:

[Resolve]
DNS=85.214.154.81
DNS=2620:fe::fe
FallbackDNS=85.215.236.86

But after the upgrade to 24.04 name resolution was just impossible. I changed DNS server addresses, I removed the symlink und recreated it. I checked if there is any other software triing to make dns, but there wasn't. If I try to ping a domain like google.com I only get Temporary failure in name resolution

The only possibility I found to be able to have name resolution is to remove the symlink and instead make a plain file /etc/resolv.conf with nameserver 8.8.8.8 as the only content, other strato nameservers don't work there.

Then I can do apt update and upgrade and ping domains. But after a while without touching (I am not yet sure how long it takes, but it is less then 12 hours) name resolution again doesn't work. Even though systemd-resolved status says it runs, without failures. A restart of the service makes name resolution functioning again.

If I google for my problem, beneath the resolved things I mentioned above, most likely it is suggested I should check my netplan configuration. But there is no netplan configuration, beacuse netplan is not installed (on the other server, that doesn't have any problems, it is not installed either).

I checked local firewall, if there is anything outgoing blocked, but there isn't. I reinstalled systemd-resolved.

On this server I am only hosting a nextcloud, nothing else happens on this server.

I am pretty sure I forgot some information you would need to help me and also forget to write soemthin I already tried as I invested multiple hours in this till now. I appreciate any hint and help with this.

The weirdest part for me is, that 8.8.8.8 as nameserver in /etc/resolv.conf works, other servers, that are reachable by there IP don't. And if I set the symlink and write 8.8.8.8 as nameserver in /etc/systemd/resolved.conf it doesn't work either. I sure miss somethin here, but I don't get what...

Thanks in advance.

Okay, again I did now:

resolvectl log-level debug
resolvectl query example.com
journalctl -u systemd-resolved -b0

And here is the section from the log I think is relevant.

I am new to all this so I probably screwed up a lot, but Xubuntu 24.04.4 was working last night. This morning it got stuck on initramfs before the login screen. I don’t even know what I did to ‘fix’ that (I know I probably broke it here, but I don’t know what I did. I’m sorry.) I think I used fsck with sda1 and sda4 and that did something. Now I’m stuck at the login screen, and nothing will type where my password would go. It’s as simple as that, it's not even typing.

I burned Ubuntu onto a 2TB SSD using balena etcher on a Mac.

I started running Ubuntu on a PC that previously had installed a Start9.com server on the hard drive. Formerly it would default to booting into the Server.

My plan was at Bootup to always select which drive to boot from.

At bootup I am able to select the USB drive that has GRC.com SpinRite installed.

But now at bootup the default it goes to is Ubuntu. When I try to select the original drive that had the Server on it, it always goes into Ubuntu anyway, even if I remove the 2TB drive Ubuntu was installed on.

Has Unbuntu hijacked my machine and destroyed my Server? Can I restore the option of picking which OS to boot into: Spinrite, Ubuntu or Start9 Server?

This forum is poorly run. I added a bunch of comments that got deleted. Someone "closed" the question which deleted them all.

===== My Server was trashed by Ubuntu. Completely erased. How do I recover?

I only want to install Ubuntu on the single SSD where I flashed the iso: ubuntu-24.04.4-desktop-amd64.iso

Was the SSD changed when I first ran Ubuntu such that I need to re-flash the Ubuntu iso onto it? I want to be able to take the Ubuntu SSD to another PC and run it without trashing that PC also.

What options should I choose running Ubuntu the first time so it doesnt trash the pre-existing OS that was installed (uncorrupted) on the HDD? So that I can choose either OS at bootup?

I have a tower running Ubuntu server and I had it configured to always display the motd on ssh login. It has been doing so without error for months and it suddenly stopped displaying today. Went through the pam.d to see if the lines were there for it and they are. The sshd_config is set to use PAM and the print motd is uncommented and set to yes. The run-parts command prints the expected results of the motd as well, no errors. I don't know what could have caused this. tried rebooting to see if it was something odd with startup and it still wasn't working. All the files have execute privileges as well

Any ideas?

This was an active issue and incident as of March 21, 2026, with resolution on or about March 24, 2026.

This issue recurred on April 1, 2026.

I am seeing a question mark on my networking in Desktop and Network Manager but my network is functioning with internet. Sometimes I am told to 'sign in' to my network even though I am already connected. (Or in some cases, people are being asked to sign into Wi-Fi when they don't have Wi-Fi.)

Why is this?

Playing audio like Spotify playlist doesn't keep Ubuntu from suspending, when "suspend after [] minutes" is turned on. I tried to find a solution for a good long while in the process of switching to Ubuntu before giving up and turning off 'suspend automatically' entirely.

Playing videos, on the other hand, works just fine and will keep my PC's screen from turning off or my PC from suspending. It also doesn't suspend while downloading files.

To be clear: I don't want to prevent my screen from sleeping while there's only audio (no video) playing.

I tried this script but I'm not sure if I installed it correctly, or if there's some other issue. It didn't work when I tested it with Spotify and it in fact seemed to stop me from manually turning off my PC by clicking 'power off' (it froze on a half dimmed screen until I clicked the physical power button).

Of course, I'd like to suspend automatically after a set time when my PC is not playing audio, to save power. Is there any way to do this? Is it maybe Spotify itself that's the problem, and if I play my music in another app it won't automatically suspend?

I want to stop my PC from suspending while Spotify is playing, even when it's playing in the background (which is why the programs that keep your PC awake when there's a full-screen application aren't suitable).

I've been trying to get an HP Omnibook X 14" 2-in-1 to work with Kubuntu 25.04 for a while now. While I've found great success, I've recently run into an issue where the touchscreen stops responding after using the stylus.

The only error that shows up in the system journal is the following, which shows up whenever the stylus is used:

i2c_hid_acpi i2c-ELAN2514:00: i2c_hid_get_input: incomplete report (67/5631)

A few things of note:

• This only occurs when the input from the stylus is used, such as by Xournal++ or Konsole, but not when libinput debug-gui is observing input.
• When using libinput debug-events, the touchscreen appears to respond normally.
• When using libinput debug-gui, the blue rectangle representing the screen tracks input properly. However, the red dot representing the cursor itself does not move when the issue is presenting.
• The stylus continues to work.
• The touchscreen works again after logout, including sleep.
• Sometimes this temporarily resolves itself.

Specs:

• Kubuntu 25.04
• KDE 6.3.4
• Kernel: 6.14.0-28-generic
• HP Omnibook x 14"

I'm happy to share log files, given you tell me where to look.

Any help is appreciated. Thank you in advance.

I have a Lenovo P1 Gen6 and recently installed 24.04.1 on it. Through my dock (Lenovo 40AN thunderbolt 3 dock) Ubuntu recognized 3 monitors (1 laptop display and 2 external monitors), but it only has picture on one external monitor. There's also another monitor that isn't recognized. These all worked with Ubuntu 22.04 as well with an early release of 24.04.

I switched to the nvidia-driver-550 and installed the synaptic DisplayLink driver.

This is what I get on rebooting now:

[    2.330459] ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-95)  
[    2.417906] ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-95)  
[    3.402894] ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-95)  
[    3.498167] ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-95)

This has been on my screen for about 10 minutes now, so I'm pretty sure I'm stuck at a black screen here.

I can't get a shell to run any commands.

I had 3 different kernels installed. I rebooted twice more selecting a different one each time. 6.8.0-40-generic worked, even without recovery, however there are a few issues:

1. Only the built-in display is recognized.
2. The built-in 4k display is only at 1920x1200 resolution.
3. Before switching to Wayland display, the console shows ^@ and when returning to console (e.g. reboot) I see there are a bunch more ^@
4. Everything else seems to work.

I guess recovery mode is out of the question ...

Now what should I do?

I have an AWS EC2 FIPS compliant 20.04 instance, I have applied the DISA STIGS to this instance, except for one. Every time I set the password for Single User mode I am no longer able to boot the server. Is this not possible on AWS? I have discovered some new information, this is only an issue with systems that are in FIPS mode. It seems like the prompt for the username and password comes up before TTYS0 is available for input. If I grab a screenshot of the machine it shows the prompt for a username, but the EC2 serial console is not available. For reference the instructions are below:

Discussion: To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems (e.g., web servers and web portals) must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access.

Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement.

Access control policies include identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include access control lists, access control matrices, and cryptography. These policies and mechanisms must be employed by the application to control access between users (or processes acting on behalf of users) and objects (e.g., devices, files, records, processes, programs, and domains) in the information system.

Check Text: Run the following command to verify the encrypted password is set:

$ sudo grep -i password /boot/grub/grub.cfg 

password_pbkdf2 root grub.pbkdf2.sha512.10000.MFU48934NJA87HF8NSD34493GDHF84NG 

If the root password entry does not begin with password_pbkdf2, this is a finding.

Fix Text: Configure the system to require a password for authentication upon booting into single-user and maintenance modes. 
 
Generate an encrypted (grub) password for root with the following command: 
 
$ grub-mkpasswd-pbkdf2 
Enter Password: 
Reenter Password: 
PBKDF2 hash of your password is grub.pbkdf2.sha512.10000.MFU48934NJD84NF8NSD39993JDHF84NG 

Using the hash from the output, modify the /etc/grub.d/40_custom file with the following command to add a boot password:

$ sudo sed -i '$i set superusers=\"root\"\npassword_pbkdf2 root <hash>' /etc/grub.d/40_custom 

where <hash> is the hash generated by grub-mkpasswd-pbkdf2 command.

Generate an updated "grub.conf" file with the new password by using the following command:

$ sudo update-grub

Origanally I have posted this question on stackoverflow, due to the fact it is the wrong forum. I'm asking the question again here with some extra information I have gathered.

I'm looking into creating a script in bash for automating my update-u^grade process for all my virtual machiens as a homelabber.

I'm a developer but currently not have that good knowledge of bash:

My current script is pretty simple:

#!/bin/sh

apt update -y
apt upgrade -y
apt autoremove -y

After some answers on Stack Overflow and some research on this forum I missed the DEBIAN_FRONTEND=noninteractive part, so I tested with this command: sudo DEBIAN_FRONTEND=noninteractive apt upgrade -y but still without good results.

The problem is that all my virtual machines have the sh config file edited with a /etc/issue.net included since this is a standard security practice founded on every information I could gather. Due to the fact that this file has been edited, while upgrading the ssh-server package it asks what I want to do. By default it will take the local edited version but it requires the user to press Enter When trying the command above I still had to press Enter, however after the upgrade was done I discovered in the terminal NEEDRESTART DEBIAN_FRONTEND=noninteractive service.

Is it possible after env variable change it need a restart to take affect? Due to the fact that the ssh package does not always have an upgrade available is there something I can do to test this?

And/or as last question: Does the env variable not change the effect for the user input?

I haven't tested my script on cron tab to see if it's is working or not due to the fact again that there is not always an upgrade available.

I am deaf in one ear and want Ubuntu to mix both left and right audio channels to mono audio. There is an Accessibility Setting for this in Windows, but I cannot find one in Ubuntu. The only Hearing Accessibility Setting I can find is for Visual Alerts. I am currently using 21.10, but also couldn't didn't see anything on my other computer running 20.04 LTS.

I saw a couple of older search results for mono audio in individual programs, but would prefer a solution that handles audio for the entire OS.

Thanks for any help.

In my current network topology I have multiple VLANs - each of which has it's own routing:

VLAN 10:
  DHCP:    10.0.10.10-10.0.10.255
  Subnet:  255.255.255.0
  Gateway: 10.0.10.1

VLAN 11
  DHCP:    10.0.11.10-10.0.11.255
  Subnet:  255.255.255.0
  Gateway: 10.0.11.1

The machine(s) I'm automatically provisioning have a single NIC. This is why I would like to avoid using static configurations and rather relay on the DHCP to provide the "correct" settings.

My yaml looks like this:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp5s0:
      # Designate the connection as "critical to the system", meaning that special care will be taken by systemd-networkd 
      # to not release the IP from DHCP when it the daemon is restarted.
      critical: yes
      dhcp4: no

  vlans:
    cloud:
      id: 10
      link: enp5s0
      dhcp4: yes
      dhcp4-overrides:
        route-metric: 200

    office:
      id: 11
      link: enp5s0
      dhcp4: yes
      dhcp4-overrides:
        route-metric: 100

The problem is it only gets the DHCP settings for the cloud vlan and does nothing with the office one. Am I missing something here?

NOTE:
This is not a duplicate of netplan with multiple vlans on single interface - help needed.

I just installed Ubuntu Server 20.04.2 LTS and have a situation where it 'hangs' after booting up.

It gets to (what I guess is) the end of the boot process, and hangs on a line saying:

cloud-init [1781]: YYYY-MM-DD HH:MM:SS,182 - cc_final_message.py[WARNING]: Used fallback datasource

The date and time changes with each boot - not sure if the '182' is part of the timestamp - I think it is, since it also changes each time.

Initially, I could press 'Enter' and it would go to login, but now it is just hanging there, and never gets to login.

I can access the server over SSH no problem, and I cannot see anything that is not working once I am in.

I found these from a while back:

https://ubuntuforums.org/showthread.php?t=2446855 https://stackoverflow.com/questions/64486060/cloud-init-not-executing-vra-cloud-config-script

which imply that it is not an issue, but pressing Enter does not get me to the login prompt now.

I have a "HP ZBook 15v G5" which I'm trying to get the "recommended" Nvidia graphics drivers working with.

Running the following suggests nvidia-driver-455 are the recommended ones:

But when I try to install them automatically I get:

Not sure if it's worth noting I did upgrade from Ubuntu 18.04 but hadn't got them working on that either.

Apologies if this is obvious, don't have much experience with graphics drivers on Ubuntu yet.

Appears I'm using the Nouveau display drivers at the moment, and I'm trying to update them to the Nvidia ones because occasionally my second monitor will go black for 10 or 15 seconds when switching applications, and then come back again:

I recently bought a new laptop (Acer Aspire One Cloudbook 14) and wanted to install Ubuntu (14.04.3) on it. I put it on a USB following this guide: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

I erased Windows 10 and installed Ubuntu. I honestly don't remember how the installation initially went as I have been trying to fix this issue for over 12 hours, I know it didn't go too smoothly, as I remember the screen showed a few errors during installation but it eventually loaded, and other than the touch pad not working, it seemed fine.

On the reboot however, I was unable to even log in.

Boot mode: Legacy:

If I have the boot mode set to Legacy, it takes me to a GNU Grub thing if my hard drive is highest priority in boot order, listing a few options (see the picture bellow).

If I select Ubuntu, that is when I get the messed up screen and Kernel panic - not syncing: IO-APIC + timer doesn't work error.

If I have USB as highest priority (again in Legacy mode) it takes me to the installation menu, though I suspect it doesn't look the way it is suppose to, but that's how it looked when I first installed it, the difference now is whether I select install Ubuntu or try without installing I get the same kernel panic error that I mentioned earlier.

Boot mode: UEFI:

If I run it in UEFI mode, it says "No bootable device" whether my hard drive (or whatever the equivalent is on this laptop) or USB is priority.

I believe I installed Ubuntu in Legacy mode by accident, which maybe caused this issue?

I have been searching online for many hours, but could not find an issue that was close enough to mine, and already tried many of the solutions of problems that were similar. Like disabling secure boot, trying different boot modes, and nothing is listed if I try to select a trusted UEFI file when hard drive is priority, if USB is priority, it just lists files that are on the USB, none of which can be selected.

I'm looking for a graphics program that will permit me to make a watermark on photographs. Can anyone advise me on this? Thank you.

I installed Ubuntu as a dual boot on a Lenovo X1 Carbon 3rd gen (with Windows 8.1, UEFI etc.; let's call it "Machine A"). I had some issue with Ubuntu there, so I removed like 3 partitions (from Windows tool) - one had 1MB, the other was main, the other was seemingly Lord fix this partition. I did not remove any other partitions that looked like the ones aimed at dealing with some internal stuff (such as deep sleep or recovery).

When I created startup disk (USB) on some other Ubuntu machine (let's call it "Machine B"), and restarted Machine A to boot from USB stick, then selected custom boot source (the mentioned USB), I saw boot loader (GRUB?) with option to Install Ubuntu, but when I selected it, I saw the following boots screen:

As you can see, there is a kernel panic related to this installation, and I am not sure what could I do to debug the issue.

Windows 8.1 is starting properly when selected as boot source, but I have some issues with virtual machines running Ubuntu (they look like they're experiencing the same issue that my machine had with that first Ubuntu installation).

Do you have any ideas on how to fix the problem, or at least can you fetch more information on it?

Today I installed:

1. Ubuntu 12.04
2. Oracle JDK 7 and 8
3. IntelliJ 11.1.4

I setup my JAVA_HOME path to point to JDK 7.

When I run IntelliJ I get this message:

Gtk-Message: Failed to load module "canberra-gtk-module"

Is this a problem or can I over look this?

I have one speaker next to my computer which I use mostly as a headphone amplifier. On occasion I need to use it as a loudspeaker. Is it possible to quickly change the audio output from stereo to mono, either system-wide or as a plugin for a media player?
