I am trying to boot Tails (tails-amd64-7.5.img) from a USB drive, but I cannot get it to boot.

The image was downloaded from the official mirror: https://mirrors.edge.kernel.org/tails/stable/

I wrote the image to the USB drive using:

• balenaEtcher
• Rufus

Both tools completed the write process without errors.

In the BIOS Boot Menu the device appears as VendorCoProductCode 3.0.

When I try to boot it I immediately get:

Missing operating system

If I disable Legacy boot and leave only UEFI enabled, the USB device completely disappears from the Boot Menu and only Windows Boot Manager remains.

If I enable Legacy boot again, the device appears again but still shows "Missing operating system".

However if I write a Windows installation image to the same USB drive, it is detected as a UEFI device and boots normally.

So the problem only occurs with the Linux/Tails image, while Windows images boot without issues.

System configuration:

• Motherboard: Gigabyte B760M DS3H DDR4

• BIOS/UEFI: Gigabyte UEFI

• CPU: Intel Core i5-12400F

• GPU: ASUS RTX 3060 8GB

• Storage: Patriot P210 512GB SSD + ST3500418AS HDD

• Secure Boot: Disabled

• Tested USB ports: USB 2.0 and USB 3.0

Does anyone know why a Linux USB would fail to boot while a Windows USB works normally on the same machine?

Problem Description:

I cannot get write permissions on my Windows 11 share. I can access and read all files in Nautlilus, but when I try to copy a file TO the Windows 11 share, I get permission denied.

What I’ve Tried:

I have permissions open on the Win11 share and I can read and write on that share from another Windows machine, I just cannot write to that share from Linux. Not sure what config files in Linux I need to adjust to achieve writing permissions to this share. I am happy to post any config files I need to but am just not sure which ones need tweaking.

Appreciate any pointers on this subject. Thanks in advance.

I recently upgraded from Ubuntu 22.04 to 24.04. Cinnamon DE. Since the upgrade, reminders are overriding power management and keep the screen enabled well past the power management display inactivity timeout. I understand these reminders are generated by the Evolution service. I like the reminders, I just don't want it to override power management. This didn't happen in 22.04, power management worked fine. Is there a way to fix this or am I stuck with either getting rid of the reminders altogether or remembering to turn off the monitor, which I don't?

I am not sure if this is a software or hardware issue.

On my Ubuntu 24.04.4, my capslock button is showing as activated (led on), when it is inactive and vice versa. Could this be a software issue and if so, how would I fix it?

I am using Ubuntu Studio 24.04. When I try to open my DAW, about 50% of the time it starts to open, but then freezes. I have to use the System Monitor to quit the application. Then I start it again and it starts up OK.

I wonder if anyone knows why this might be happening. I sometimes have Firefox open while opening the DAW. I wonder if it might be a Pipewire thing. I have tried keeping Firefox closed before opening the DAW, but it still happens.

I just installed Ubuntu 24.04 LTS succesfully on a PC, and it runs nice and smooth...

When finishing installation I chose encryption of the disk (LMV and encryption), and I agreed on a encryption password. I got the password notet, so no problem there.

But it's a PC...

When I'm prompted for the password (please unlock /disk dm_crypt-0) , it is under boot-up and therefore before my blootooth keyboard is activated. For this reason I would like to unlock the disk permanently without a password.

How and where in the setup can I do so, if possible?

Thank you very much in advance.

Regards, Ole

I'm on Ubuntu 22.04. Only a few months ago, I had Webmin installed, but I had to remove to free up space. When I try to install now, I get an error message about an unmet dependency:

Trying to install perlapi-5.28.0 with APT told me that it couldn't be found or sometihing. I found this Launchpad page that says the package I can download from there provides perlapi-5.28.0. I downloaded it and tried intalling it manually. I got some errors, so I reinstalled perlapi-5.34.0 and now I'm getting this on trying to install Webmin:

Given that I had Webmin installed not too long, this should be working. How do I fix it?

When I see a stable, well-accepted package like coreutils get removed, my initial reaction is something of shock. However, I know the danger of "speaking without knowledge" to use the biblical wording, and that the Ubuntu people know way more about this than I do, but:

Why did the Ubuntu team want to change from coreutils to uutils?

I know there's a big push for "safer" languages like rust right now, is simply that the reason? or is there a more complex reason? It seems like a mature project like coreutils would no longer have any memory leaks or similar errors that might make the Ubuntu team have second thoughts about using it. So, why?

Just a note for those who don't know, this is not in an LTS release yet, just in intern releases.

The Problem

So I recently updated my ubuntu desktop from 25.04 to 25.10, and ever since i did that i haven't been able to get into ubuntu anymore, anytime i boot it goes through the loading screen into a black screen that just sits there forever, trying to open TTY just flashes the terminal for a split second before going away.

What I've Tried

I've tried the older kernel, I've tried fixing system packages and cleaning up everything in recovery mode, and I've also tried using boot-repair on a live usb, nothing has solved the issue. I'm running off amd and suspect it is a driver problem but im not sure. I've tried running ubuntu with nomodeset in the grub menu but it gives the same output and claims dkms.service failed to start. I've tried using chroot on a live usb to rebuild dkms modules but i have no idea how to use chroot and couldn't get it to work with DNS. I have no idea what I'm doing and I desperately need help please.

Ubuntu 24.04

usually using VS code multiple workspaces but when need to switch beetween diffrent workspace from task bar icons of vs code, then always use to click on All Windows option and then it opnes list of all windows and we need to select a window. same for chrome and other applicaton also. see attached screenshot

so I was looking for any keyboard shotcut for the same, to get all open windows and choose/pick, although showing multiple dots near task bar icons means there are multiple instances of the application windows.

I know hard links can't cross filesystems, but trying to link files via bind mounts that physically live on the same filesystem fails as well. I detailed things below to visualize it better, but the TLDR of my question is why is ln treating the mounted directories as though they live separately?

Basically, copying files into a share folder would be best-served with hardlinks so I'm not duplicating space:

mymedia/
├─ share/
│  ├─ pics/
│  │  ├─ pic2.tif
│  ├─ vids/
│  │  ├─ vid1.mov
├─ homevid/
│  ├─ vid1.mov
│  ├─ vid2.mov
│  ├─ vid3.mov
├─ homepic/
│  ├─ pic1.tif
│  ├─ pic2.tif
├─ training/

mymedia/share is on one drive (Media1), whereas homepic is on Media2 and homevid on Media3. The two folders in share are mounted from Media2/Media3. This is from fstab:

/dev/disk/by-uuid/UUID_1 /mnt/Media1 auto 0 0  
/dev/disk/by-uuid/UUID_2 /mnt/Media2 auto 0 0  
/dev/disk/by-uuid/UUID_3 /mnt/Media3 auto 0 0  
/mnt/Media1 /mnt/mymedia none bind 
/mnt/Media2/homepic /mnt/mymedia/homepic none bind
/mnt/Media2/share /mnt/mymedia/share/pics none bind
/mnt/Media3/homevid /mnt/mymedia/homevid none bind
/mnt/Media3/share /mnt/mymedia/share/vids none bind

I can create the link while using the "real" path, like so: ln /mnt/Media2/homepic/pic2.tif /mnt/Media2/share/, and see the new file in both directories; stat confirms the inode is the same for the files, as well as same device:

Unfortunately, using the bind mounts would be way better for my workflow (this fails): ln /mnt/mymedia/homepic/pic1.tif /mnt/mymedia/share/pics/pic2.tif

What am I missing?

I run into a well-known problem that was actually already widely discussed on the web. However, I unfortunately could not solve the problem yet.

I recently replaced the Wifi network adapter into a new one, Intel(R) Wi-Fi 6 AX210 160MHz, in a Dell Rugged 5414 laptop, several years old.

I'm still fairly new to Linux/Ubuntu and appreciate any assistance.

I just installed Ubuntu Budgie 22.04 on my new ASUS Vivobook OLED S15 S3502 (2022). The keyboard is not working while the touchpad is working. But the external keyboard is working fine.

How can I make it work fine?

I have researched this error, and from what I can understand I ought to install gcc-multilib to resolve it. But I run into problems with this too:

The following packages have unmet dependencies:
 gcc-multilib : Depends: gcc-9-multilib (>= 9.3.0-3~) but it is not going to be installed

Trying to install gcc-9-multilib gives further and further dependency problems. Researching this, I found this thread, where they solved the gcc-multilib issue, but unfortunately it doesn't work for me. I get the same dependency issues as in the original post. Their solution was to downgrade libc6-dev running "sudo apt install libc6-dev=2.31-0ubuntu9.2". When I do this, it says:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
libc6-dev is already the newest version (2.31-0ubuntu9.2).
libc6-dev set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So I already have the version that resolved their problem, but my problem remains.

Any suggestions on how to resolve this, and most of all get the HTK library running would be very appreciated.

For the life of me I can't get that network icon back. I have restarted the X server, ran "nm-applet" and restarted NetworkManager. Any ideas? I can provide output for commands if needed.

I'm trying to configure a dual boot between Kali Linux and Ubuntu. I have already installed Kali in one partition with about 40G. The rest of the size will be asigned to install Ubuntu. This is how my kali linux partitions looks:

Kali partitions

As you see the kali linux is encrypted with luks and use lvm. I want to do the same with the Ubuntu distro. I have created the partitions for ubuntu like this:

Ubuntu installation partition

the /dev/sda4 is the partition where i need to put ubuntu.

This is the lvm configuration, with a root filesystem and a swap.

Ubuntu lvm

Then when i try to install ubuntu, it show this error The 'grub-efi-amd64-signed' package failed to install into /target/ . Without the GRUB boot loader, the installed system will not boot

I'm using uefi to install the partitions.

What i've done wrong with this setup?

I am following the steps listed here to try to get my WD Passport Wireless Pro 3TB HDD to work with Lubuntu 18.04: http://tutodir.com/how-to-mount-wd-my-passport-wireless-pro-on-ubuntu/

I run into the title error below:

Windows 10 has a feature to enter BIOS/UEFI directly from the OS, which is handy for machines that do not allow you to enter them during startup.

I would like to install Ubuntu on an OEM device and obviously I will be using the Windows feature to do this, but I will still require BIOS access in the future.

How can I access the BIOS from Ubuntu?

I performed a fresh install of Ubuntu 18.04 LTS on my desktop that I've been using Ubuntu on since Ubuntu 11.04. As I'm setting everything back up and installing all of the 3rd party software I regular use, I noticed in /var/log/syslog that everytime I press the Backspace key on my keyboard is generates the following errors one after another:

Aug 4 18:44:49 mycomputer org.gnome.Shell.desktop[3044]: Window manager warning: Overwriting existing binding of keysym ff09 with keysym ff09 (keycode 17).

Aug 4 18:44:49 mycomputer org.gnome.Shell.desktop[3044]: Window manager warning: Overwriting existing binding of keysym 73 with keysym 73 (keycode 27).

I also notice a short stutter anytime I press the Backspace key (small delay then Backspace starts doing it's thing). Any ideas what the heck this might be and how I can resolve it?

I'm using a Corsair K90 keyboard which hasn't had this issue the past and I didn't configure any custom hotkeys yet so it's not related to anything that I specifically changed regarding key mappings.

One thing I can mention is while I didn't upgrade over my existing Ubuntu installation, my home directory hosted on separate drives was already populated with my personal files and configs from my apps so I'm wondering if something in there that was carried over may be causing this.

Any help is appreciated and please let me know if you need any additional information.

I was having problems answering a call in Skype, no answer button, and so I decided to reinstall Skype from scratch.

This is Xubuntu with lsb-release showing

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.4 LTS"

Ran this morning

apt-get update
apt-get dist-upgrade
sudo apt-get autoremove --purge skypeforlinux

Get Skype from https://www.skype.com/en/get-skype/

Downloaded skypeforlinux-64.deb

sudo apt install ./skypeforlinux-64.deb

Started Skype from the menu.

Obtained the Skype window outline but no body, just what was showing under where the body should be. It just hangs there and I have to kill the pid to close it.

Gnome-boxes begins to start then crashes on my account. However, I created another account and boxes loaded fine. I tried to delete the files in ~/.config and ~/.share but no luck.

I am trying to install TeamViewer but I'm getting this error:

dependency is not satisfiable libpng12-0

How do I resolve this issue?

I'm currently using two 2k monitors and a third 4k monitor. Is there any way to use max resolution on all of them and scale things up a bit on just the 4k monitor? I've been digging around for ages but it seems the only option is to use Windows 10.

If it's not obvious - things look tiny on the 4k monitor, it's hard to read. And using 2k resolution on a 4k monitor looks terrible.

sudo chown proftpd /etc/proftpd/ftpd.passwd sudo chmod o-r /etc/proftpd/ftpd.passwd sudo service proftpd start

At this stage proFTPd is running but I am unable to log in,

sudo chmod o+r /etc/proftpd/ftpd.passwd

And now I can log in to FTP However if I change the permission on the ftpd.passwd to sudo chmod o+r /etc/proftpd/ftpd.passwd before I start the proFTPd , the proFTPd won't start and will give me the error:

mod_auth_file/1.0: unable to use world-readable AuthUserFile '/etc/proftpd/ftpd.passwd': Operation not permitted Fatal: AuthUserFile: unable to use /etc/proftpd/ftpd.passwd: Operation not permitted on line 36 of '/etc/proftpd/proftpd.conf'

What my suspicion is that proFTPd is not a member of a specific group, if I execute:

groups proftpd

proftpd : nogroup is the reply.

Any ideas?

What is the difference between:

sudo chown $USER:$USER

and

sudo chown $USER

Why is it 2 times? Is the one user wrong? When I look at permissions with namei -l, I often see things like root root or proxy proxy.

Why does the owner have to be defined and listed 2 times?
