I'm using Ventoy
When i'm trying to boot any ISO, it gives me errors
error: invalid magic number.

error: you need to load thekerel first.

Press any button to countinue

I installed Linux before on different laptops with that flash. I've already tried to update it, or re-install Ventoy. Nothing. Now It has the same problem when im booting on mine regular laptop. I cannot use Rufus cause i don't have any Windows devise

Quisiera probar fedora porque algunas características me llamaron la atención, sobre todo algo que escuché fue el creador de Linux, utiliza esta distribución. Soy desarrollador web, docente y creador de contenido de videos sencillos.

Fedora sería una buena distribución para mí?.

No lo voy a utilizar para juegos ni para diseño gráfico ni nada muy pesado para las computadoras, más que todo porque tengo especificaciones un poco deficientes.

He utilizado ubuntu y Debian, o sea que estoy familiarizado con el entorno linux.

My friend's laptop needed an upgrade and because of how much I glazed linux he decided to try it, i went to his home and had my tools ready, a laptop, a usb drive, and a bunch of ISO's, i showed him different DE's and distros, we tried to install arch (i told him i would be his tech support lol) but for some odd reason the iso was broken, we tried cachy os but it didn't work either, even when using other cachyos boot options, his laptop is dell Inspiron n5110, it's too old to have secure boot, it has an Intel gpu ALONGSIDE an NVIDIA gpu, and they are ANCIENT i tried ISO's on my machine and they worked just fine, on cachyos it stuck at loaded graphical interface, also his font was strangely weird, i decided it was another nvidia problem so i went and made intel the default from bios, but it still didn't work out. I didn't want to try mint and Ubuntu because he wanted something that's new, fast and cool, while mint is just a super fast windows (from the outer shell ofc) I'm so frustrated and I'm taking it as a challenge, please help. Sorry for bad English

I was given the above computer, and thought I'd set up a self hosted server on it as an experiment. I have now spent over 12 hours trying to get it to connect to my internet, to no avail. I first tried Lubuntu due to me being scared of running a headless is, immediately ran into issues, troubleshot, gave up, installed Ubuntu server instead, same issue.

I feel like I am not savvy enough to even explain what's wrong, but I have scoured every damn forum I can find with similar problems.

From what I'm gathering it's lacking drivers and support, that need to be installed, but I can't install them due to no internet...

I realize this is a worthless plead for help because of no real world info, but my brain is so burnt out that this is all I have.

I guess what I'm wondering is if anyone has the same computer, managed to get anything to work, or if this machine is just a dead end and I should give up...

I'm using Kubuntu and the default printing menu doesn't have even have half the features as my windows PC.

I'm looking for a program that has options for double sided printing (both long and short side binding), print multiple faces per page, select which pages to print (odd, even, custom selection), and a preview screen to show what your print will look like.

These are standard features on every other printing interface I've used, I'm astonished I can't find anything on linux that has these (not to mention when I look for "linux printing software" 95% of what comes up is related to coding and not paper).

Any ideas? Thanks reddit army.

Hello! I’m not new to Linux; I used it as my primary (and only) operating system from 2011 to about 2018 (Ubuntu, Fedora, Arch, Debian, etc.). Since then, I’ve used Windows exclusively—mainly because the PC was intended solely for gaming, and I didn’t want any unnecessary complications (please don’t crucify me for switching to Windows!).

I’d like to start using Linux again from time to time, and I want to run it on actual hardware rather than in a VM. Since I’ve rarely (if ever) set up a dual-boot system, I have a few questions about how to partition my drive for this.

My setup includes an i7-13700KF, an RTX 4080 Super, and 32GB of DDR5 RAM. I’m running Windows 11 in UEFI mode with "Fast Startup" disabled; Secure Boot is enabled (and must remain so, due to certain games).

Regarding storage, I have two 2TB NVMe drives. Windows and some games are installed on the C: drive, while the D: drive holds a large collection of other games. I can’t dedicate an entire drive to Linux (and I don’t need that much space for it anyway), so I could free up about 500GB on the D: drive for a Linux installation.

How should I partition that 500GB space? Do you have any recommendations for this dual-boot setup? In the past, I’ve run into issues where the system time would be incorrect when switching back to Windows after using Linux—how can I prevent that?

My goal is to minimize any impact on my current Windows installation. I even considered using a small-capacity external USB SSD, but I feel that wouldn’t quite be the same as a "real" hardware installation, given the limitations of a USB connection.

Any general tips on how to set up this dual boot? Thanks!

So, i fairly recently moved form windows 10 to mint, then to cachy and Ive now moved to Arch. I used Arch install because im still a noob, but i really liked the idea of having an absolute barebone install that i could slowly build up myself with exactly only what i wanted on there. I did however use this system for gaming very successfully in CachyOs, so I opted to install the Cachy Kernel and repos. So I now have my Arch install + Cachy Kernel and i setup snapper with BTFRS. I am pretty happy with this setup, but I have thought to myself.. have I just basically installed CachyOS the hard way? is this setup pointless? or is/was there some benefit to my setup aside from the sometimes fun..sometimes infuriating learning process?

So, i have a problem which idk how to fix. My Mercusys red antenna just doesnt work, and i tried installing some drivers i found on GitHub but nothing worked

System: Nobara Linux + KDE Plasma

My model: i think MU60HE or something like that

Drivers: rtl8812cu/5.8.0.14 (or similar)

Good morning linux users.

This is one of my first times using linux, for a laptop I’m converting into a writing-only distraction-free device.

I’m using Linux Lite 4.8 and LibreOffice 6.0.7.3

I just want to use a Dark Mode type theme for LibreOffice Writer. In the theme settings it requests a Firefox theme URL, or to search/browse within the same window in the app.

But no matter what I try, I can’t paste a URL, download a compatible theme, or search in the built in theme window.

Can anyone help me apply a dark theme in this old version of LibreOffice please? Thank you

my partitioning is really bad I'm sorry😭😭 I don't have a spare drive or anything to back up my data so it has to be like this for now. I know that it's not a very good practice to put ntfs and ext4 partitions on the same drive

so I'm trying to go from mint to debian while keeping my /home and all the other directories and I got super confused about the boot loader

I tried mounting sdb1 as /boot/efi on the new install, but debian complained that it has to be at least 300 MB in size, so I guess that's the windows' boot loader? where is the grub's installation then? or /boot/efi I guess

also if I go to my boot priority settings in UEFI, grub shows up as ㅤㅤㅤㅤ for some reason so i have no idea which drive it is on

i really wish I could just wipe that other windows nvme but there's like 2 programs that don't work on linux no matter what i tried

honorable mention fuck AI, if it wasn't for data centers I could just buy a bigger nvme for windows stuff and not have to go through all of this

Rtx 3060 12400f 16gb ddr4 adata legend 700 512gb m2 ssd (This is the disk I will use for the installation) samsung evo 870 evo sata

Nobara 44 Official and KDE ISOs both fail Media Check.

ISO SHA256 checksum is verified successfully.

Tried Rufus in DD mode and Linux Mint USB Image Writer, with similar results.

Nobara Live Desktop boots, but installation fails during the final nobara-sync stage with an external command error.

Garuda Linux fails to install the NVIDIA driver, resulting in extremely poor desktop performance.

Btrfs (also ext4) installation fails with:

The installer failed to create

partition on disk 'ADATA LEGEND 700'.

LVM reports:

Device /dev/nvme0n1p3 has size of 959206984 sectors which is smaller than corresponding PV size of 994787944 sectors.

The ADATA NVMe previously contained Windows and multiple Linux installations. It was repeatedly cleaned using Windows DiskPart clean before attempting new installations.

The Samsung SSD contains Windows and personal data and is not the target installation disk.

Question: Could stale LVM metadata, GPT partition table inconsistencies, or a Calamares partitioning issue explain the installation failure? Has anyone experienced the same combination of errors?

Previously, I had set up this system with Windows 10, Windows 11, and the default Ubuntu-based Linux Mint distro. GRUB let me boot to Mint or the Windows boot loader where I could boot into 10 or 11. But I wanted to replace the default Mint partition with Linux Mint Debian Edition, and after installing it my system instead boots to a GRUB command line prompt and sits there waiting for me to enter commands.

If I run a few commands I can boot to LMDE or my Windows partitions from there, but I have to look them up on another system each time and I don't know how to make it stick. I want to keep at least Windows 10 otherwise I would have just wiped the entire disk.

What is wrong with my GRUB that it doesn't know how to point to my partitions anymore, and how can I install LMDE so that I get the expected GRUB behavior where it gives me the option to boot to LMDE or Windows and automatically selects one after a few seconds? Thanks.

ETA: Also, how does the boot process work now anyway? I used to feel like I had a grasp on it a few decades ago but not anymore. How can there be a Windows Boot Loader and GRUB at the same time? Could there be more than one GRUB instance now?

I tried running update-grub after booting to LMDE but after I rebooted I had the same problem as before.

I recently installed Arch and have been frequently running "sudo pacman -Syu" as I thought it kept the system up to date, but I saw someone talking about updating scripts in a video. Does the command I've been using not fully update the system? If not, I'd like to learn how to actually update it before my system ends up all out of whack or something 😅

Let me give you a little context: This is my first time installing Ubuntu, and I’m slowly starting to realize the problems that come with it. I mean, I’ve already finished the installation, but I’ve run into the huge SNAP space issue, the library dependency problem, and who knows what else. I just wanted a program that could save or get my old PC—which is about 5 years old—working properly again. With Ubuntu, I’m managing to do that more or less, but I wanted to explore other alternatives or just get some recommendations
I realize it's impossible to make my 2018 laptop perform like my main desktop computer, but I want to see if I can get the most out of my old computer (since it runs relatively well on Ubuntu)

sorry for the read

Situation:

I’m building a pc to mainly play bg3 with my brother but no distribution so far has install and play support, so I start troubleshooting. Over the course of somewhere north of 50 hours of total troubleshooting, I’m spent and asking for help.

Problem:

As stated, I’m stuck at the reboot phase of changing drivers so as to fully use the 1080. Got bazzite to start up with the correct iso as per the bazzite website. When starting bg3 it would drop to 10 fps or less. I forced display through the 1080 and got 800x600 resolution, at the time I didn’t know what drivers were so I swapped to Pop!_OS because I thought Bazzite was the problem. Since then I’ve learned about the 470-580 drivers required for the pascal architecture inside the 10 series and learned about the Software&Updates application found in the cosmic store. When trying to swap between any of the available drives it would apply but the restart within the app wouldn’t respond, so I would restart through the power icon in the gui, and later through the terminal. When it starts the boot process it shows the Pop!_OS logo for roughly 10 minutes then a black screen with a blinking white horizontal bar, typing doesn’t seem to do anything, no matter which driver I try. I’ve learned this is likely a conflict with nouveau and the nvidia driver and figured out how to blacklist nouveau but it still keeps happening. I’ve tried inputting all the major specific drivers between 470 and 580 through the terminal to no avail and trying to use the apt-mark hold because I found something that said the drivers get automatically updated to past 580. I’ve tried downloading from the NVIDIA website and patching it into the file system. I‘ve been through the grub menu to input a command at the end of some boot code to try and force boot into a shell and fix the configuration there but it never managed to boot into the shell. I know it’s not a secure boot issue. I have tried both 24.04 and 22.04 versions of Pop!_OS with both the nvidia versions that are said to not work as well as the non-nvidia versions for everything pre-1600. I honestly don’t remember everything I’ve tried but after following so many directions to a T and it not working, I’m just done.

Specs:

HP EliteDesk 800 G1 TWR

Intel Core i7-4790 (8) @ 4.00 GHz

Intel Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics

NVIDIA EVGA FTW3 GTX 1080 ti

asrock 750w psu

tried bazzite-nvidia:stable, pop_os 24.04 & 22.04 so far and from reading around I might try mint just cause, and thank you to anyone who puts some thought into this.

Is Samba Registry for File Shares still a valid method nowadays? Or is it deprecated?

vssh — Dynamic Libvirt/KVM Guest SSH Helper

vssh is a lightweight Bash helper function with dynamic tab-completion designed to make SSHing into local libvirt/KVM virtual machines effortless. Instead of manually looking up changing IP addresses via virsh net-dhcp-leases default or maintaining static /etc/hosts entries, vssh resolves guest hostnames to their active DHCP IP addresses on the fly.

Features

• Dynamic IP Resolution: Queries virsh net-dhcp-leases default at runtime so you always connect to the VM's current IP, even after DHCP lease renewals or reboots.

• Dynamic Tab-Completion: Automatically populates available active guest hostnames when you press Tab.

• Interactive Login Prompt: Prompts you for a target username (defaulting to root on Enter) before passing control to ssh for password or key authentication.

• Pass-Through SSH Flags: Supports standard ssh options (e.g., -p, -X, -i, -v) appended after the hostname.

• Quick Lease Overview: Running vssh with no arguments displays all currently active DHCP leases on the default network.

Prerequisites

• A Linux host running libvirt / KVM.

• virsh installed and accessible by your user (ensure your user is in the libvirt group, or configure LIBVIRT_DEFAULT_URI="qemu:///system" in your environment if needed).

• Guest VMs configured to report their hostname to the default libvirt DHCP server (dnsmasq).

Installation

1. Add the code to your ~/.bashrc

Open your ~/.bashrc file in your preferred text editor (e.g., nano ~/.bashrc or vim ~/.bashrc) and append the following block to the bottom of the file:

# Dynamic SSH to libvirt/KVM guests with interactive username prompt
vssh() {
    local target="$1"
    shift # Remove target from arguments so remaining flags can be passed to ssh
    
    if [ -z "$target" ]; then
        echo "Usage: vssh <hostname> [ssh-options]"
        echo "Active leases on 'default' network:"
        virsh net-dhcp-leases default 2>/dev/null
        return 1
    fi

    # Dynamically find the IP address for the given hostname
    local ip
    ip=$(virsh net-dhcp-leases default 2>/dev/null | awk -v host="$target" '$0 ~ host {
        for(i=1; i<=NF; i++) {
            if ($i ~ /^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/) {
                sub(/\/.*/, "", $i);
                print $i;
                exit;
            }
        }
    }')

    if [ -z "$ip" ]; then
        echo "Error: Could not find an active DHCP lease for hostname '$target'."
        echo "Check available hostnames using: virsh net-dhcp-leases default"
        return 1
    fi

    # Prompt for username interactively (defaults to root)
    local user
    read -p "Username [root]: " user
    user="${user:-root}"

    echo "Connecting to $user@$target ($ip)..."
    
    # Connect (SSH will prompt for the password interactively)
    ssh "$user@$ip" "$@"
}

# Enable dynamic tab-completion for vssh based on active DHCP leases
_vssh_completions() {
    local cur="${COMP_WORDS[COMP_CWORD]}"
    local hosts
    hosts=$(virsh net-dhcp-leases default 2>/dev/null | awk '{
        for(i=1; i<=NF; i++) {
            if ($i ~ /^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/) {
                if ($(i+1) != "" && $(i+1) !~ /^[0-9]+/) print $(i+1);
            }
        }
    }')
    COMPREPLY=( $(compgen -W "$hosts" -- "$cur") )
}
complete -F _vssh_completions vssh

2. Reload your shell configuration

Apply the changes to your current terminal session:

source ~/.bashrc

Usage

List active VMs and DHCP leases

Run vssh with no arguments to see usage instructions and a live table of active leases:

vssh

Connect to a VM using tab-completion

Type vssh , press Tab twice to view or autocomplete active VM hostnames, and press Enter:

vssh ubuntu-server

You will be prompted for the username:

Username [root]: ubuntu
Connecting to ubuntu@ubuntu-server (192.168.122.45)...
[email protected]'s password:

(Pressing Enter without typing a username will default to root*.)*

Pass additional SSH options

Any flags provided after the hostname are forwarded directly to the underlying ssh command:

# Connect on a custom port with verbose output
vssh fedora-workstation -p 2222 -v

# Enable X11 forwarding
vssh debian-desktop -X

Troubleshooting

• Tab-completion returns nothing / virsh returns empty output: By default, running virsh as a non-root user may connect to qemu:///session instead of qemu:///system. To fix this, add the following line to your ~/.bashrc above the vssh function:export LIBVIRT_DEFAULT_URI="qemu:///system"

• Password prompt does not appear (Permission denied (publickey)): Ensure password authentication is enabled inside the guest VM (/etc/ssh/sshd_config -> PasswordAuthentication yes) and that the SSH service has been restarted.

Hello! I'm looking to switch onto linux, and i've got some programs i need to keep for university use, arcgis pro, google earth pro, steam and R Gis.

I was looking at endeavour os but im unsure about the compatibility, or if i should start with a simpler distro like mint. Thank you so much for the advice!

I have just about zero experience coding or using the command on windows, just for reference to my inexperience. I'm confident I'll learn as I go and know the risks in using Linux. My question is very straight forward; how do I everything from back up of original hard drive, to where I download all the necessary files and whatever system would be most compatible with my HP for Linux, to installing drivers, etc. I'm also curious if I could fluidly run windows and Linux with this base version laptop, and not have problems. I appreciate any of y'all that choose to answer and let me know if you have any questions please, and thanks again!

I bought a switch specifically for starcraft 2, which is only avaliable on the blizzard client. What do i use?
