I'm unable since today to start the Postman application that I installed using snap.
I've been running it since years now and it won't start anymore.
I tried starting it from the terminal and it gives me this error +a large stack trace with references to ERR: Display.cpp:1083 ...

A JavaScript error occurred in the main process

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.

this is my first question, please excuse any noob mistakes. I am following the Installing Broadcom Wireless Drivers post Installing Broadcom Wireless Drivers on here.

The article states that if your pcid is not on the list then you need to create a new question. Once the new question is solved then the answer will be updated to the article mentioned above.

So I have run into the special case where I have a pcid that is not on the list. My pcid is: 44e4:4464 (rev04) I have a fresh new install of Ubuntu Studio on a 2018 mackbook pro. I have run the basic updates already by connecting my phone via usb.

Looking for steps to get this wireless card working. I am new to linux so I will need basic step by step instructions.

Using clean 2T disk in 1 bay of MacPro 5,1 with .iso flashed USB install, install seems normal until an 'unknown' problem occurs. Trying to start from resulting disk gives blank screen with question marked folder. I tried clean disk wipes, several USB sticks & flashes w/Balena Etcher & different .iso downloads. I tried w and w/o internet (wired) connection, w and w/o suggested installer update and restart. Tried 23.10, 25.10, with same error result. Mac Pro 5,1 3.33 GHz 6-Core Intel Xeon, ATI Radeon HD 5870 1024 MB, 32G RAM. Help?

I don’t know what I’m doing wrong so can you guys please help me?

I need to raise my file limits above the default. There are numerous web pages explaining how to do this, They are unanimous in recommending editing the appropriate parameters in /etc/security/limits.conf. Mine is a personal laptop that is on my home network and no one else has access. But when I open this file I see only commented out lines explaining how to edit this file; it has no active content, and yet somehow my limits are 1024 for both hard and soft. If I add the following two lines

*       soft    nofile 2048
*       hard    nofile 2048

and log out and in, the limit remains 1024. Is there some other file that this distribution uses for this config? And why do these changes not work?

I have a Dell OptiPlex 7080 SFF, BIOS 1.36.0, Intel Code i5-10500, Intel Ethernet Connection I219-LM. I am using Ubuntu Desktop 18.04, 22.04 & 22, Ubuntu Server 22.04 and 24.04.

I am using a variant of Ubuntu and my computer, the internet is not working. This is the simple solution, but it's not working.

The installation of Ubuntu started. The internet did not work, so had an update for the I219-LM. From Intel I installed it to download release_30.5.1.zip. I used the PRO1000 section and used make to use src. Then I tried to push to change updates and then reboot. This did not work. I'm still having problems.

I recently experienced a complete system freeze on my notebook (with no mouse or keyboard response), and the only solution was a forced shutdown. To avoid potential filesystem corruption, I formatted the machine and performed a clean installation of Ubuntu 20.04.6 LTS from Dell’s official website.

Installation details:

• ISO: Ubuntu 20.04

• USB drive: SanDisk Generic

• Bootable media created using Rufus

• Installed on SSD

• Installation finished normally with errors about reading files, e exactly 4 files

After reinstalling, the system runs perfectly during normal use. However, every time I shutdown or reboot, I consistently get these messages:

Failed to unmount /oldroot: Device or resource busy

Failed to unmount /oldroot/dev/**

Failed to finalize file systems; ignoring

This issue did not happen before the reinstall.

Commands I have already tried:

• sudo touch /forcefsck && sudo reboot

• systemd-analyze blame

• systemd-analyze critical-chain

• mount | grep oldroot

• Even after these tests, the error continues to appear during shutdown.

My questions:

1. What might be preventing /oldroot from being unmounted during shutdown?

2. Could the installation USB created by Rufus be responsible?

3. Should I recreate the boot media using Startup Disk Creator / Balena Etcher / dd and reinstall?

4. Which log files should I collect to find what is holding the mount?

5. Does this issue pose any real risk to my SSD or filesystem integrity?

Any help or guidance will be greatly appreciated. Thank you!

I am trying to upgrade my Kubuntu 25.04 to 25.10.

I am doing it through the command line, using sudo do-release-upgrade.

I am getting this error message:

...
Calculating the changes

Not enough free disk space 

The upgrade has aborted. The upgrade needs a total of 6,819 M free 
space on disk '/var/cache/apt/archives'. Please free at least an 
additional 534 M of disk space on '/var/cache/apt/archives'. 

My /var partition (ext4) has a size of 119 GiB, of which 33 GiB are used. So there is plenty of space available. Why am I getting this error?

Could this be an issue of the upgrade option? Should I do a clean installation?

These are my partitions:

I use VLC to monitor a DVR via RTSP. Suddenly it stopped connecting. I have tried everything I can find, but it still fails to connect.

VLC version is 3.0.16 Vetinari. It used to work, then about a week ago, it started to fail, giving:

"Your input can't be opened: VLC is unable to open the MRL rtsp://192.168.1.195:554/ch04/0. Check the log for details."

I have tried removing and reinstalling, both with Symantic and sudo apt install, which I think means snap. I tried sudo apt-get install, but it makes no difference. I have a log output, very long, but I cannot understand what it is telling. I can post it if it would help.

This first started on my daily-use Desktop, for a day the backup laptop worked, then it also failed. I assume there was some kind of update that borked it. The laptop has 3.0.20 Vetinari.

EDIT

I followed the instructions in Sotirov's abswer, but it did not solve the problem. After doing exactly what I was told, the command: vlc rtsp://192.168.1.195:554/ch04/0 led to the usual hint as to how to get 'help', and also it opened vlc with, again, the same fault as before.

Rebooting made no difference. I am thinking of seeing if I can install an earlier version of vlc, to see if that helps. I think this is 'editing my question post'. If not, I can only apologise. Results:

david@desktop-2:~$ which vlc
/usr/bin/vlc
david@desktop-2:~$ vlc rtsp://192.168.1.195:554/ch04/0
VLC media player 3.0.16 Vetinari (revision 3.0.13-8-g41878ff4f2)
VLC media player 3.0.16 Vetinari
Command Line Interface initialized. Type `help' for help.

and it waited for input. This time, it did not launch vlc, which it did before.

Using an HP Elitebook 845 G7. I have attempted several times to perform a clean install of Ubuntu 24.04 with TPM-backed full disk encryption (FDE), but I am unable to get my recovery keys after the install because the first boot asks for my recovery key, so I am unable to get to the login screen.

My Steps

1. Insert the installation USB

2. Enter Startup Menu (Esc on HP devices)

3. Go to BIOS Setup (F10)

4. Go to Security and Restore Security Settings to Factory Defaults

   1. There is a prompt asking you to confirm that you want to reset security settings (yes)

   2. Then another prompt asking you to confirm clearing the TPM (yes)

5. Once it reboots, go to Startup Menu again, then Boot Menu (F9)

6. Boot the installation media, select Ubuntu (Safe Graphics)

7. Update the installer when prompted

8. Open terminal and do: sudo fwupdmgr refresh; sudo fwupdmgr update (I heard from this Reddit reply that it fixed the same issue for someone else, but in my case it didn't work)

9. Restart installer

10. Choose to install Extended selection ("offline-friendly collection of...")

11. Choose to install media formats but NOT third-party drivers (I have heard this can interfere with TPM FDE during installation)

12. Under Advanced options for installation choose TPM-backed FDE

13. Create login info, etc.

14. After the installation, close installer

    1. At this point I even tried sudo snap recovery --get-keys from the live USB just to try it but I knew that I needed to actually do this from the installed Ubuntu environment.

15. Restart and remove installation media when prompted

I was then presented with a command line asking me for my recovery keys, which I did not have because I could never log in in the first place.

Any help appreciated.

Note: This thread doesn't really answer my question because this problem occurs on first boot, so I have no access to my recovery keys, therefore I cannot update the kernel

I am unable to install openssh-server in Ubuntu Budgie 24.04.3. I tried the install first and got a message saying that it couldn't find the package, so check your repositories. I found that the repositories for main and universe were unchecked in the Software app - no idea how they got unchecked. So I checked those boxes and ran an update. Then tried the install again, and got the following output showing a conflict with openssh-client:

dan@kirby:~$ sudo apt install openssh-server
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 openssh-server : Depends: openssh-client (= 1:9.6p1-3ubuntu13) but 1:9.6p1-3ubuntu13.13 is to be installed
                  Depends: openssh-sftp-server but it is not going to be installed
                  Recommends: ncurses-term but it is not going to be installed
                  Recommends: ssh-import-id but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

So I ran an apt-cache policy query and got:

dan@kirby:~$ sudo apt-cache policy apt openssh-client
[sudo] password for dan:

     1:9.6p1-3ubuntu13 500
        500 http://archive.ubuntu.com/ubuntu noble/main amd64 Packages

So somehow I've got the wrong version of openssh-client, which you can't remove because it is a dependency of about a hundred desktop packages. I tried apt --fix-broken install but it doesn't do anything. Any ideas on how to fix this?

Hello I am attempting to change the ownership of the /data and /docker mount points I created to the 'thomas' user I created. When I run:

thomas@media:/data$ sudo chown -R thomas:thomas /data

I get the error:

chown: cannot read directory './lost+found': Permission denied

The user thomas has already been added to the sudo group.

Thanks

I try to install Ubuntu Desktop 24.04.2. But when I create an user in installation guidance, the user's password is seemingly required to be stronger than 4 digits.

But I want to use 4 digits password.

How I can remove this regulation in the installation step?

(I really don't need the kind of "You should use stronger password" advice.)

For some time now I have been wondering if verifying the PGP signature and sha256 hash are actually needed to check if there is any malware in the downloaded ISO. Evertime I try to google this, i get the same answer: sometimes/maybe/it might be useful. I'm trying to find a yes or no for this question since all the answeres I can find are doubtful.

So I have the folling questions: Do I need to verify the PGP signature to be sure that my OS has not been compromised from the start? Do I need to verify the sha256 hash to be sure that my ISO file has not been compromised?

Thanks in advance!

I am currently taking lots of screenshots of online presentations. I get a notification for them all. I cannot find a toggle switch in Settings to turn off for ONLY this application.

Where do I turn off the notifications for the "Take a Screenshot" tool s there are no configuration options obvious.

Thanks

I posted this question a few days ago.
I tried to reinstall the driver by downloading it from official NVIDIA website and also reinstalling it from Additional Driver app or ubuntu-driver autoinstall command but none of them solved the problem. I can install them without any error but after reboot I face some problems (whem PRIME profile is on-demand). Now nvidia-smi doesn't work:

┌──(root💀ubuntu)-[~]
└─$ nvidia-smi 
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

nvidia-persistenced.service has beed failed to start and I get this message:

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 have a Logitech G512 Carbon (wired USB keyboard) and am sick of using the FN key to pause music or adjust the volume. I use Logitech software on Windows to turn on the fn lock to access media keys directly (without holding fn). Is there a way to do this on Ubuntu? I haven't been able to find a solution for this.

EDIT:

Things I tried:

• Solaar
• Bunch of key combinations that are meant to activate fn lock. Looks like this keyboard does not support that

The computer still seems connected to the wifi but it says there is no connection to the internet; When I try to open the wifi settings I get the "Oops, something has gone wrong. Please contact your software vendor. NetworkManager needs to be running". Moreover, everything looks incredibly slow, When I try to run any sudo command in the terminal to try to restart the network manager it just does nothing and let me in "blank space" in the terminal. Plus I can't turn off the computer from the Power off/Log Out option, and I have to restart it from the mechanical button. Once restarted it works, but it's extremely annoying and unpredictable, plus, working on cloud systems, it causes me to lose stuff most of the times it happens.

Here is my concerning.

a. the size of kernel1.cpio was changed from 56M to 31M, something seems to be losted.

b. the size of kernel2.cpio was changed from 56M to 21M, something seems to be losted.

c. the total size of split zip files xk.zip xk.z01~z07 is around 110M, why the combined zip file yk.zip is only 51MB?

Am I wrong?

Things I tried and did NOT solve the problem:
I tried to disable autosuspend for USB ports by adding linux kernel cmdline: usbcore.autosuspend=-1 among many other options and they all failed.
I also tried to change multiple BIOS options related to USB, nothing helped.


Useful Facts:
- All USB 2.0 4-ports are causing the problem.
- The board has single USB 3.0 port which seems unaffected by the problem.
- Using powered USB hub connected to the USB3 port, then connecting all USB devices to it seems to solve the problem.
- Using 32bit version of the same OS seems to solve the USB problem. Tested some kiosks with 32bit installation for 3 days uptime and there were no single dmesg warning or error.

Question:
How can I solve this problem on my 64bit Ubuntu 16.04 ?

Converting to 32bit is an unrealistic solution for me as it requires the reinstallation of over 100 devices. Besides, some of my equipment comes with 64bit proprietary SDK.

Update 1:
The problem seems to be unrelated to the CPU architecture and it happened after a while on Ubuntu 14.04-32bit and 16.04-32bit

My Ubuntu 16.04 WiFi is not getting connected to my Bluetooth speaker. Even when I try searching for the new device it is not showing anything though the speaker gets connected to my smartphone. My smartphone also doesn't show my laptop's Bluetooth though the visibility is on.

I have checked blockage, it says no.

There is a similar problem for Ubuntu 14.04 but the solution doesn't work for me 16.04. Bluetooth not detecting any devices

This is the error I get: E: Unable to locate package rtl8723au-bt-dkms

I tested for this:

lsusb; dmesg | egrep -i 'blue|firm'

The output was:

Yesterday I posted a question detailing that my system was reacting badly to proprietary NVIDIA graphics drivers. Having now tried at least 5 different NVIDIA drivers (304, 340, 368, 375, 381 - I think, it's hard to keep track of them all) I'm beginning to shift my sights to only use the Nouveau drivers.

However, I noticed that a "nvidiafb" kernel is installed when using lspci to diagnose the drivers that were currently installed.

From what I gather Nouveau does not play well with proprietary NVIDIA drivers and the two cannot run simultaneously. As the resolution is currently locked to 640x480 within Nouveau I pose 2 questions:

1. What exactly is nvidiafb? I did not install this manually to the best of my knowledge.
2. Would nvidiafb have any impact on Nouveau's behaviour? If so, how do I uninstall the former to test this?

I see also that Nouveau actually had an update yesterday. It was suggested that this may have broken the compatibility with the display device. Therefore: is there anyway to revert to the previous version?

Operating System Version: Ubuntu 16.04 LTS

Graphics Card: NVIDIA GTX 670

I have been using Ubuntu for: 6 days (So I'm still very new!)

I downloaded my professor's "shell" program and am trying to run it on my machine to do some homework. When I tried to run it from terminal using ./shell I got a "Permission denied error". After running chmod 777 shell I tried runninging it again, only to get the "no such file or directory" error. I'm not sure why this is happening as I can still see the executable using ls. When I check the permissions of shell I get -rwxrwxrwx 1 ubuntu ubuntu 9403 Feb 16 03:45 shell so I'm not sure what the matter is. Can someone help me get this thing running?

Output of file ./shell:

./shell: ELF 32-bit LSB  executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

Output of uname -a:

I am experiencing the problem described here: https://productforums.google.com/forum/#!topic/gmail/n1cpJq1mC8U.

Google Hangouts appears to be resetting the levels of my microphone.

That post has a solution:

To turn off the auto adjust:

cd ~/.config/google-googletalkplugin    # get to google chat's directory
cp -p options options.bak        # make a backup before changing stuff ! 
gedit options                # edit the config file

now change one of the lines so that it reads as follows:

audio-flags=1

So far, so good. The problem is that I don't have a folder ~/.config/google-googletalkplugin.

My Hangouts works perfectly apart from the mic, so I guess I don't need to install anything, but how do I configure it?

I can write æ and ø by pressing down Alt Gr + a and o, respectively.

However, trying all keys on my keyboard using Alt Gr, I've not yet found a way of writing the letter å.

I've been looking into character codes, but by pressing down Alt and entering the character code 0224 etc. nothing happens.

Can someone show me how to solve the problem (I am a danish user...)

I own a new Lenovo S20-30 laptop which came with Windows 8.1 preinstalled with the hard drive partitioned. I want to convert this laptop to Ubuntu 15.4. with NO dual boot. I want it to be an exclusive Linux machine. This laptop can boot off the E Drive with a USB Drive.

I used a brand new Kingston 4 GB USB Drive. I followed Ubuntu installation instructions to the letter

1. I went to Pendrivelinux.com and downloaded the Universal USB Installer V1.9.5.9 to my USB Drive.

2. I went to Ubuntu and downloaded Ubuntu Linux V15.04 to my USB Drive.

3. Using The Universal USB Installer I installed Ububtu Linux 5.4 on my USB Drive.

4. My BIOS is updated to the latest BIOS from Lenovo's Website, which was posted on March 9, 2015, Filename/BIOS Version: accn22ww(v2.08&v1.1).

5. My BIOS is configured to boot from the USB Drive first

6. When I reboot the USB Drive is not recognized as a boot drive and the system still boots into Windows.

Again, I want to boot up and install Ubuntu Linux 15.04 and have the system be an exclusive LINUX machine. I have an identical Lenovo S20-30 rynning the standard Windows 8.1 and want to compare functionality and performance running the same applications on identical machines.

Has anyone installed Ubuntu Linux on a Lenovo S20-30 before?

What do I need to troubleshoot and check?

I am an experienced Windows person but new to Linux so please be gentle and don't assume I know much about Linux. That's what this is all about, I want to become Linux expert and hope I can one day soon be fully on Ubuntu Linux and never look back

I went back in to my BIOS and look at the configuration very carefully setting by setting. I was finally able to find the best combination of BIOS settings to get my Lenovo S20-30 to boot up from my USB Drive and Ubuntu 15.4 is fully installed now as the ONLY operating system on myS20-30.

I have painstakingly documented every BIOS setting below along with the settings I changed to sucessfully boot up from my Ubuntu Boot USB.

So now its time tolearn learn learn Ubuntu. I hope my post below proves helpful to others.

Here is some additional BIOS Information

Note for Boot Mode:the information window states: Windows 8 or 8.1 64 Bit please useUEFI Boot Mode. Other Legacy OS please use Legacy Support Mode

Additionally I havereset the Bios to Legacy Support with the same result whenbooting up

When selecting BootMode of Legacy First I am presented with two choices for“Boot Priority”. 1. Legacy First 2. UEFI First

Withthe following note: Determine EFI Device first or LegacyDevice first. If Enable it is the EFI Device first,If Disable it is the Legacy Device First

I did cold boots with each combination selected: UnsuccessfulBoot configuration to boot from the USB Drive: LegacySupport UEFI First

I have an 8GB SSD that had Windows 8.1. I was using a text editor and it locked up on me. I tried to format add a new partition and nothing happen. So I'm using Ubuntu on a external SD. I can read the drive in the BIOS and in the OS, but I can't delete or do anything to it. I checked online on how to erase and clear the 8GB SSD by using the command shred. I did and I got this error message: fdatasync failed input and output error. How can I wipe the SSD and reformat it? I know it can be done, because I have done it with another machine that had Windows 8.1 but was using SATA and diskpart. When I try to mount it I get this error message:

Error mounting /dev/sda1 at /media/bigby/6A9CA8A19CA868F1:

NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

so I have a simple sh file I want to run whenever someone logs in. I tried adding it to startup applications. This didn't work. I tried editing the .desktop file for the startup application to set Terminal=true. This made it open temporarily but shut it down. I tried editing .bashrc by adding the command bash /path/to/my/file.sh and it had the same effect. This seems like it should be really simple to do, even in linux, but I have tried lots of ways and had no success. I am on Ubuntu 14.something.
