OS: Ubuntu 24.04.3 LTS with daily updates. Partitions on USB2: W95 FAT32 (LBA)

After copying the files from USB1 to USB2 I can no longer change the ownership and permissability of the (sub-)files. I tried chown and chmod for eight hours with all possible options (-c, -R, -f, -Rf, +rwX, u=g, g+wrX... -- I tried everything), it tells me files only readable. Right-clicking on the device I get only readable. sudo doesn't help at all, I even can't change the permissions as a super-duper-user. The problem is: I can't even copy simple files to the new USB2, it's completely shut.

Is there a way apart from chown and chmod to force USB2 into a normal USB-drive where I can copy files into, change file and whatever? I need some super power far beyond sudo chown and sudo chmod, as they change NOTHING.

I'm a new hire in a B2B context, specifically at a CNC machining factory. My probation period is contingent on generating customer inquiries or orders. While the company, culture, and technical operations are excellent, I am struggling to get my first lead.

As a thought experiment and a potential way to jumpstart my pipeline: If you were in my position, how would you leverage your network or online communities (professionally and ethically) to demonstrate initial market interest? For example, if someone here genuinely needed a service like CNC machining, even a request for quote would serve as a valuable data point for my activity.

I'm seeking strategic advice on generating legitimate initial traction quickly.

This is probably a very easy thing to fix but all of the questions and answers I found are for problems using a BT USB dongle. I have a Ubuntu 24.04.3 LTS Desktop that is running on an ASUS Maximus VIII Formula motherboard that supports BT v4.0/3.0+HS natively (no USB dongle needed).

sudo service bluetooth status

shows that bluetooth is enabled but Active: inactive dead. In settings the bluetooth on/off slide control is greyed out.

I did install bluez and bluez-tools.

bluetoothctl power on

If I try to power BT on I get the error message Unable to open mgmt_socket

Someone running an ASUS M8F powered desktop probably knows the answer off the top of their head. I did have this running on 22.04 LTS but it stopped working after the 24.04.3 LTS upgrade

Again, this is NOT a USB BT dongle. The BT hardware seems to be discovered and has been enabled but there is still a small piece that's missing to create/open the socket and power on BT.

That said: inxi --bluetooth returns

Bluetooth: Device-1: ASUSTek Qualcomm Bluetooth 4.1 driver: N/A type: USB

Many thanks in advance.

Recently I decided to reuse an old laptop to start my first Ubuntu server to learn more about homelab and devops and setup my NAS. When I was poking around, I accidentally run this command chown -R $USER:$USER .. and it mess up my sudo files and lead to my problem, at that moment I was not able to physically turn on Recovery mode to do reset the ownership of sudo (fixed when I got home). But this wonder, can I revert or fix this over remote ssh. I did try to use a few method mentioned by ChatGPT but I still not convinced that I cannot fixed over the remote ssh. Is there another way for me to fix it if I can't reboot the machine?

P/s: This is my first time working with linux and I am still learning.

I just signed up for VPN.net and downloaded the linux for intel processors: vpnet-linux-3.7.4-00346.run. It says I don't have permission.

How can I perform an upgrade of Ubuntu 16.04.6 LTS (Xenial Xerus) to the next versions (18.04 → 20.04 → 22.04) on a PROD server without internet access?

What's the best practice to achieve this? Is there any official documentation I can follow?

thanks and regards !

I am not an expert Linux user. I've setup Ubuntu server 24.04 on an Intel N100 mini PC for use as a Channels DVR, getchannels.com. Could someone let me know if I've mounted an external drive correct to hold the recordings for the DVR? See fstab below. It shows when I run lsblk. See below. The Channels setup doesn't see the drive when I click Restore to go select a restore point on the external drive.

Update:

Not being familiar with using servers I discovered I could access the drive in the /mnt folder. I tried to enable it as the DVR server and I got this error message:

Error: no write permissions on dvr directory: open /mnt/dvr/.permcheck: permission denied

This drive was used when the Channels DVR had an image to use on a Raspberry Pi 4. They maintained the server besides the software. They stopped supporting that so I needed to setup a server myself instead of using Windows for it. I thought I could just use the drive from the Pi without reformatting. Does anyone know if I would need to reformat the drive on the server so it have the correct permissions to use as storage for the server?

I'm looking at the file structure I've created and maybe losing my mind. Somehow my terminal seems to be telling me there are different files/folders in what should be the same place

The OS is most recent Linux server. I hope to make into a media server. I'm using Samba to connect my MacBook (tho in this case of the ssh I don't think that should matter. In the screenshot you can see the GUI interface matches the second request.

Specifically there's 3 folders in the first ls and then there's 4 different folders and a file in the ls -l /mnt/media, but I'm currently in /mnt/media so that should be the same?!?

I can't understand why there's such discrepancy, but it is making me think I messed up something installing 22.04. I'd rather not start over again, but it might be faster and I would really like to understand what I did wrong.

I'm on Ubuntu 24.04.3 and getting very poor geolocation accuracy with Firefox's default setup (which relies on GeoClue). I tried switching Firefox to use the Google Geolocation API with my own key, but it still only returns coarse IP-based results.

After a fair bit of debugging, my current hypothesis is that the Firefox snap build is sandboxed in a way that prevents it from accessing Wi-Fi scan data (e.g. no network-manager interface in snap connections firefox). Without Wi-Fi BSSID data, Firefox falls back to IP-only location, which explains the poor accuracy.

Before I migrate to the apt-based Firefox, could someone confirm whether this is indeed a snap confinement issue, and whether the apt build restores proper Wi-Fi-based geolocation? Also, is this a known limitation, and are there any plans to address it in future Firefox snap releases?

When I start Firefox from Application or from Dash, Firefox start as I expect. All my setting are applied. If I start Firefox from "Startup Application" it looks diffrently. From System Monitor I find this command line:

/snap/firefox/7355/usr/lib/firefox/firefox

I put it into Startup Application and Firefox ask me to select one from four profiles and look diffrently from I expect in all four profiles.

When I start Firefox from Application/Dash I see only one profile "Original profile".

How to start Firefox from "Startup Application" to behave the same as start form Application/Dash?

I'm using Kubuntu 24.04 and when I first installed the OS everything worked fine with the microphone, when I plug my headset it detected the microphone without any problem, I could switch between the internal and the headset microphone and it correctly eliminated the headset mic when unplugged leaving the internal mic working.

I don't know when this happened, but one day I noticed that the sound picked up from the "headset mic" wasn't right and was instead the internal. Now even when the headset is unplugged it still appears the "headset mic", but it is really the internal and when I switch to the real internal it doesn't pick up any sound. The audio works fine though. Can this be a fix or do I need to reinstall all the sound drivers?

I reinstalled Ubuntu several times. The first 3 times, everything was normal. But on the 4th installation, a new 918 MB “Healthy (Recovery Partition)” appeared in Windows Disk Management.

I already have:

260 MB EFI System Partition

Windows C:

100 GB Ubuntu partition

260 MB recovery partition (original)

NEW 918 MB recovery partition

I’m worried because earlier when i want to install ubuntu I unplugged my USB during a stuck boot and got a kernel panic. Did that create the 918 MB partition? Why do I suddenly have 2 recovery partitions when other people usually have only 1?

Since Ubuntu 25.04, I have issues the wifi connection. My motherboard has a Qualcomm FastConnect 7800 WCN785x card. Three cases (appears random to me)

1. No Wifi "5 GHz" when listing available networks, but the 2.4 GHz appears. In such case, iw reg get returns

phy#0 (self-managed)
country 00: DFS-UNSET

2. Wifi 5 GHz looks fine, but the bandwidth is slow, right now, for example, 144 Mb/s (5.2 GHz). In such case, iw reg get returns

phy#0 (self-managed)
country FR: DFS-ETSI

3. Wifi 5 GHz works fine with good bandwidth (about 800 Mb/s). In such case, iw reg get returns

phy#0 (self-managed)
country FR: DFS-ETSI

The 3rd case seems to appear only when it's not working in the beginning and I do iw reg set FR (I'm in France), although it affects only global and not phy#0. It also appears that if I start the computer in Power Mode: Power Saver (or Performance?), I am more likely to be in case #1 and if I start in Balanced, I am more likely to be in case #2.

For sure, case #1 didn't happened prior to Ubuntu 25.10 upgrade but it's not clear when bandwidth issues started, but it's been few months. I first thought I changed something at home, so I put the wifi access point closer to this computer, but it didn't change anything.

If I boot with the previous kernel, 6.14, instead of the 6.17, I always end up in case #2.

iw reg get gives different output between Linux kernel 6.14 and 6.17

As reported in the topic On Ubuntu 24.04, Qualcomm FastConnect 7800, which supports Wi-Fi 7 and Bluetooth 5.3, has Bluetooth working, but Wi-Fi is not or here Install Qualcomm Wifi Driver this card was not working with the latest LTS Ubuntu 24.04, hence the update to minor versions. It was working fine with Ubuntu 24.10. I cannot pin point the time this issue started, but I think with Ubuntu 25.04, as the first symptom was a slow bandwidth, which I did not notice immediately.

There is at least an issue with regulatory (allowed frequencies), but it's difficult to investigate since wifi management changed recently and existing topic looks obsolete (no more iwconfig nor iwlist, crda seems outdated as well).

I was running snap remove cups on my Ubuntu 22.04 system because I wanted to re-install "cups" directly via "apt" instead of running it as a snap. While this snap remove cups was running, I wanted to kill a different process, but I accidentally chose the PID for that snap remove cups process, and that process was killed.

Now, I get the following output for the following commands (and note that I'm running all these commands as root):

snap remove cups
    error: snap "cups" has "remove-snap" change in progress
snap remove cups --purge
    error: snap "cups" has "remove-snap" change in progress
snap disable cups
    error: cannot disable "cups": snap "cups" already disabled 
snap enable cups
    error: snap "cups" has "remove-snap" change in progress
snap install cups
    snap "cups" is already installed, see 'snap help refresh'

    29   Undo    today at 16:22 EST  -                   Remove "cups" snap

When I run snap abort 29, this doesn't produce any output and exits with return code 0, and it doesn't change anything, and the snap commands that I listed above still give the same results.

I rebooted, and this doesn't change anything, either; I still get the same results for all those snap commands.

Obviously, my accidental killing of that snap remove cups process caused this situation.

Does anyone know how I can fix this and get the "cups" snap to be totally removed?

Thank you in advance.

UPDATE: Also, running snap refresh doesn't fix this problem. The refresh succeeds with return code 0, and all the above snap commands still return the same results.

FURTHER UPDATE: I'm hoping for a solution to this problem which doesn't involve something as drastic as a complete uninstall-followed-by-reinstall of snap ... if at all possible.

I am trying to run ubuntu 24.04 LTS on a (65 GB) partition alongside windows 10. I am doing this on an Asus UX530UQ (intel core i7, NVIDIA GeForce 940mx). I have tried many things and have attempted to use AI to assist in solving this issue. I will do my best to summarise everything. I created a bootable USB once with balenaetcher and another time with rufus. with rufus I selected GPT and UEFI. Every attempt to install ends with "something went wrong"

Beyond this point I have tried to use AI to help but have failed many times. Most of the stuff I tried was from within a live USB 'Try Ubuntu' terminal window or within the bios. Below are details of what has been attempted: disabling secure boot and fast boot. checked boot order (was already prioritising Ubuntu) updated bios (now 312, which is the latest) have tried Grub reinstallation several times verified mounts in chroot. used efibootmgr have tried MOK and got through to MOK menu but still resulted in the same outcomes.

regardless of what I have tried so far I end up either with "prohibited by secure boot policy", "bad shim signature" and "tried both default and fallback boot entries" or it boots directly into memtest.

I can still access windows and can access the 'try ubuntu' through the USB.In both cases I can access the internet. It does seem that ubuntu is installed I just cant get it to boot properly. I know AI has its limitations and was not necessarily the best course of action but I wanted to give it a go. Alas I have not been able to resolve the problem. If possible I would like to get it to work with secure boot and fast boot enabled. It is my first time posting, if there is anything I can improve in my query or any extra information I can add please let me know. Thanks in advance for your help.

I really have this problem since long ago, but despite extensive research I did not find any satisfactory solution.

The main issue is the laptop randomly freezes after I close the lid (sometimes it works, sometimes it doesn't).

I suspected it was an update issue, so I started doing sudo apt update && sudo apt upgrade every time before closing the lid, and checking if I was asked to reboot, but it didn't change much.

Sometimes after, updates were all ok, but after leaving (closing the lid) and coming back I funded the laptop freezed. Or not...

When I come back and open the lid, I see the light that indicate that the laptop is still on, but it doesn't respond to any keyboard key, and I'm forced to shut it down to turn it on.

After going on it shows the "Software Center" indicating the last updates and actualization it have done. Some times it have something to do with important system actualization, but not allays.

My system specs:

• (Linux 6.8.0-85-generic #85~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 19 16:18:59 UTC 2 x86_64 x86_64 x86_64 GNU/Linux)

In /var/log I have really a lot of lines, but I really don't know what I can post here that can help... Does someone may have any idea what can I do, or what I should check? gracias!

I’m having trouble getting my MediaTek MT7902 WiFi card to work on Ubuntu 24.04 the last version of Ubuntu with kernel 6.8.0-51. The card works fine on Windows, but on Ubuntu, no networks are detected.

Details:

1. The card shows up in lspci:

00:02.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902]

2. ip link output:

2: enx022376651f09: <BROADCAST,MULTICAST,UP> mtu 65536 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 1000

3. Firmware (linux-firmware) is up to date.

4. I loaded the mt76 driver (modprobe mt76), but it doesn’t seem to work.

5. dmesg gives:

read kernel buffer failed: Operation not permitted

What I’ve tried:

• Updated linux-firmware.
• Loaded the mt76 module.
• Restarted NetworkManager.
• Unblocked WiFi using rfkill unblock all.

Question:

How can I get this WiFi card to work on Ubuntu? Do I need a specific driver, firmware, or kernel version?

Thanks for your help!

i have this annoying warp-cli top bar icon on the Dash to Panel (normally on top bar) warp-cli icon

it indicates warp-cli status but i want to hide it. how i can do it? please help me.

Using Ubuntu 22.04.01 LTS, Gnome 42 for Extensions.

additional info (https://community.cloudflare.com/t/warp-taskbar-icon-on-a-linux-desktop/377862)

This used to work but after a samba server upgrade anything that I am trying to "get" via an smbclient is returning "getattrib: NT_STATUS_NOT_SUPPORTED"

In my client, I simply execute smbclient //mypc//sharename -Uusername and then I key in the password. This works ok and I can see directory listing and traverse into the directories.

As soon as I try to pull a file using smb's get command, it gives me this error

getattrib: NT_STATUS_NOT_SUPPORTED

The only thing that changed was an updated Samba server. My smbclient is up to date and I am sure it should be some configuration in smb.conf

PS: Before this problem I wasn't able to connect, and had to add client max protocol = SMB3 not sure if this helps.

I am trying to use smbclient in my Ubuntu to get a file from a Samba share into this ubuntu server. However, it gives me the mentioned error instead.

Any insight would be appreciated.

The webcam resolution during Microsoft Teams (and also Zoom and Meet) work video calls seems to be something like 16:9, which shows a lot more of my (messy working from home) background than I want.

I would like to set the aspect ratio as 4:3 and zoom in a bit so that my profile is centred on the screen. How can I do this in Ubuntu?

I installed V4L2 Test Bench from Ubuntu software and this allows me to set the aspect ratio for video within that app, but these settings do not apply to the video conferencing apps.

So I have upgraded from Disco to Eoan, so far quite 'interesting' I needed to rebuild Grub to get a GUI - took a while but finished and I'm using the PC. Today I've been getting numerous browser crashes so my first thought is to run both sudo apt update sudo apt upgrade. That was a disappointing exercise. here's the output from update "3 packages can be upgraded. Run 'apt list --upgradable' to see them."

so cool, I don't care what the packages are, just upgrade them so after I type in apt upgrade I see this in the terminal

This was unexpected so I did run apt --fix-broken install and lo !

So it would seem that I cannot update or upgrade because of some dpkg problem

Any tips or clues ?

Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
 The following packages have unmet dependencies:

linux-image-generic: Depends: linux-modules-extra-5.3.0-45-generic but it is not installed

I have no 3rd party repositories

How shall I install both curl and mongodb

The .cache folder(The folder with cache) is eating up my space most of the time and I always how to clear it. How do I get Ubuntu to automatically delete every cache file, including clearing the recycle bin whenever it deletes it but only files that were in the cache folder not the ones deleted by me?

In Ubuntu 17.10 the command

find /Home/khemtit/Documents/Tijdelijk/ -mtime +1 -type f -delete>$

delete my files older than 1 day. But I have no result in combination with a cron.

Could you please inform me about my mistake in the line below?

My command is:

15 00  * * * find /home/khemtit/Documents/Tijdelijk/ -mtime +1 -type f -delete>$

By Ctrl+O I do see the text:

File Name to Write: tmpcrontab.OV51lh/crontab

I believe the cron is installed correctly because “service cron status” gives the message:

cron.service - Regular background program processing daemon
   Loaded: loaded (/lib/systemd/system/cron.service; enabled; vendor preset: ena
   Active: active (running) since Mon 2018-01-29 18:29:16 +07; 5min ago
     Docs: man:cron(8)

    Tasks: 1 (limit: 4915)
   CGroup: /system.slice/cron.service
           └─861 /usr/sbin/cron -f

My Problem:

Ubuntu doesn't shutdown/reboot and is stuck on line like this:

/dev/sda: clean, xxx/xxx files, xxx/xxx blocks`

and sometimes with several similiar lines and sometimes with "recovering journal" at the top.

At first the problem was that it stucked with

CPU#X stucked for XXs

but I've managed it somehow from the list below :)

What I've done:

1. sudo update && upgrade && dist-upgrade and loaded updates with ubuntu-software-center.
2. sudo purge nvidia* and sudo apt-get install nvidia-361
3. switched to Intel HD card in "Nvidia settings" (nvidia prime).
4. fixed grub with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force
5. (tried apm=power_off and acpi=noirq too).(tried apm=power_off and acpi=noirq too).
6. disabled usb 3.0 legacy mode.
7. disabled swap partition with sudo swapoff /dev/sdaX and commented it's entry in fstab.
8. I changed something in /etc/modules that I've forgotten

My hardware:

MSI GE62 6QD (Laptop);
i5 6300HQ (4 cores);
intel hd530 + Nvidia gtx 960;
16gb RAM DDR4;
Windows 10 UEFI on default 1TB HDD;
SSD Intel 540s via M.2 (UBUNTU UEFI);
Dualboot via bootmenu (F11) yet..

I just didn't update kernel manually, but I can try if you'll help me a little with right way of doing it.

Installation process didn't go easy too. It got stucked on first "preparing" screen with "Ubuntu" logo. Solved with nomodeset in boot params. I've tried hackintosh OSX El Capitan on this M.2 SSD and it worked rather fine (of course not excellent).

I'm very sorry, cause I'm not a guru in kernels/terminal/bootargs/etc, so I tried almost every solution that helped somebody..

Hope for your help. I need my lovely OS working well on my new monster-laptop.

I am trying to run a java program which list all available ports using Eclipse IDE in Ubuntu 14.04. My program is as follows:

import gnu.io.CommPortIdentifier;

import java.util.Enumeration;


public class ListAvailablePorts {

public void list() {  
    Enumeration ports = CommPortIdentifier.getPortIdentifiers();  

    while(ports.hasMoreElements())  
        System.out.println(((CommPortIdentifier)ports.nextElement()).getName());
}
public static void main(String[] args) {
    new ListAvailablePorts().list(); 

}

}

But it shows the following warning followed by error:

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library     /usr/lib/jvm/java-8-oracle/jre/lib/amd64/librxtxSerial.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

Is there any way that drivers installed in one Ubuntu device can be installed in another device? Some type of transfer of drivers from one device to another.

If I try to launch firefox I get:

Bus error (core dumped)

When, until last week, I had Gnome 12.04 it was the same... then, during the upgrade (I now have 14.04) Firefox started working (without Flash Player). I installed Flash Player and Firefox stopped working.

Since I am no expert at all, in this answer I honestly don't understand what does "Simply activate it by going to System Settings>Software Sources>Other Software and check the boxes for Canonical Partners" mean (I have the box for Canonical Patners checked, if that is).

I tried the following things found on the Web:

• If firefox -safe-mode it's the same

• Tried sudo dpkg --purge --force-all firefox , then sudo apt-get install firefox , nothing.

• Disinstalled Flash Player, useless

• Like suggested here, rm -r ~/.mozilla . Too bad for me.

• Then nothing removing ~/.config/dconf/user, whatever

Help!
