ich kann leider nicht aktualisieren. Die Erst-Installation erfolgte ohne die UEFI Berücksichtigung soweit ich mich erinnere. Boot/efi ist aber eingehängt...Das Kontextmenü erlaubt das Aushängen...Kann jemand helfen? Ich möchte eine Neuinstallation vermeiden...Siehe Screenshot. Ich bin normaler Anwender...Danke schonmal.

Gruß Ralph

Trying to install Ubuntu on Samsung NP930QDB-KD3US, the installation copies files and so forth normally until a fatal error that grub-install fails.

There is no dual-boot, and Windows was removed.

I tried this with Ubuntu 24.04 and 26.04. I tried with full-disk encryption and without it. I tried numerous setting changes in CMOS/BIOS, including making sure Secure Boot was disabled.

Under 24.04, I tried formatting the internal volume /dev/nvme0n with a 256MB EFI partition as /dev/nvme0n1, a 2GB /boot as /dev/nvme0n2, and a 512GB / as /dev/nvme0n3. Under 26.04, the installer automatically assigned EFI to /dev/nvme0n2 when creating /boot as /dev/nvme0n1, but the configuration was otherwise the same.

I tried both installing GRUB to /dev/nvme01n and to the EFI partition.

I tried manually overwriting the first gigabyte of the volume

dd of=/dev/nvme01n if=/dev/zero bs=1M count=1024

What totally mystifies me is that MX Linux (MX-25.1_Xfce_ahs_x64) installs and works with no trouble; it is based on Debian 13.3 (trixie). Whatever the problem is must be specific to Ubuntu.

tl;dr how do I specify a user and password within a wget .wgetrc file for a specific website?

I want to create a ~/.wgetrc file for wget that stores a user and password, e.g.

user=user1
password=s3cr3tPass

But this username and password is only for website www.website.com. How can I modify the ~/.wgetrc so that this authentication data is only used when communicating with URLs with hostname www.website.com?

In my case, I cannot use the password on the command-line, so the pass value must be stored in some file which is loaded by wget.

I am trying to upgrade 22.04 lts to 26.04 lts. I understand I must upgrade to 24.04 first and then upgrade to 26.04. I have tried to do so, but the upgrade process fails. (I have a screen shot of the terminal window showing the errors.)

Note: I am a ham radio operator and want to upgrade WSJT-X to version 3.0.0. It apparently will not install on Ubuntu 22.04.

I've installed an ubuntu 26.04 on a laptop of mine to use it as a Minecraft server, I've retrived a map we were playing with friend to host it by myself on this laptop.

It is a modded Minecraft, the modpack name is Prominence 2.

I have succesfully installed the server, I run it, and I can join the world from my other laptop, but after around 1 minute I am loosing connection and disconnect from the server.

On the server log, just before disconecting there is an error saying:

[Netty Epoll Server IO #3/ERROR]: Exception occurred in netty pipeline

My friends have the same issue, and I tried to install and run a vanilla server and the issue is not present, so I assume my issue come from my Ubuntu installation but I cannot tell..

Does anyone have any idea what is happening?

Here are the server's and client's logs:

Thank you for your time and have a great day!

While upgrading from 25.10 to 26.4 I had power failure. Trying to continue I was prompted to partial upgrade which, when tried, is shutting out the upgrade procedure. Messages popping up when trying Partial Upgrade but nothing happens.

i'm playing a game called Mordhau, and there is a mod to play the lute. I tried installing it but i never succeeded. Anyone who can help me?

I was trying to download one SAP application but i got the error message that I have no space left in /var/tmp. After some search, I found that the /var/tmp/opt directory is the cause of this.

One file in particular is kern.error:

• kern.error inside /var/tmp/opt = 4.9 GB

• cache = 741 MB

• lib = 2.0 GB

• log = 1.4 GB

Can I delete those files inside /var/tmp directory or is it not allowed?

I have a question concerning the creation of a customized live CD. I have already found and followed the advice from the 'creating a custom live CD from scratch' page, but that was years ago and I found it to be quite a hassle.

I switched to Debian a while back after a system drive crash because I wanted to try the root distro of Ubuntu and the likes. I found its live-build package a very handy, simple and powerful tool to create customized Debian live CDs.

I use the live-build tool to create a clone (package-wise, with some custom config files added) of my current running system so I can reinstall it and have everything I use ready without the hassle of remembering and reinstalling everything after I install a new computer (or when I mess up my current install, which almost never happens anymore due to 20 years of Linux experience).

I discovered Ubuntu also has the live-build package and I found an entry on an Ubuntu dev website mentioning that they were switching from their in-house script to live-build (This was back in 2011).

I installed Lubuntu in a VM and installed live-build, but no matter how I configure the auto/config script, the process keeps quitting on me due to errors. lb config runs fine, but live-build build keeps spitting out errors.

The first error is due to start-stop-daemon not being installed. After installing this manually in the chroot (it's part of the dpkg package, but does not get auto-installed during bootstrap / creation of the base system chroot for whatever reason I cannot seem to discover) I encountered the second error.

The second error is:

'cp: cannot stat 'chroot/boot/.bin': No such file or directory'

I have no idea what the live-build script is even attempting to do here, besides that is happens right after it starts installing memtest.

Now I am wondering: am I doing it wrong? Did I misconfigure something? Or is the live-build script in Ubuntu broken, as someone on another webpage said? (I cannot find that source at the moment, so there's no link, sorry).

How are the Ubuntu devs building their live CDs nowadays? Do they still use live-build? What configuration do they use, and where can I find that configuration?

I have installed Ubuntu 24.04 on a new system Lenovo M90a Pro Gen 4 Desktop (ThinkCenter). Everything works fine except the sound from internal audio speakers. I can hear sound through Bluetooth headphones though. I have tried other LTS versions of Ubuntu including the latest Ubuntu 26.04. My sound cards and audio drivers are detected properly, but there is no sound. I tried every possible solution from ChatGPT and Gemini, but nothing worked. I am attaching the screenshots. Does anyone have any thoughts?

Unfortunately Lenovo denied support as they said they do not provide support for all OSs although my new machine is still under warranty. They only provide support for those that come with Ubuntu preinstalled.

Chrome crashes with "FD ownership violation" and exit_code=133 on Ubuntu 20.04, kernel 5.15.0-139, Intel UHD 620. Started after system reboot today. VS Code also broken. Firefox works fine. Error: "Crashing due to FD ownership violation" when running chrome --type=gpu-process --no-sandbox

I have used ubuntu on servers for many years but the file rights are still playing with my brain.

I don´t think I use ACL.s

I use samba and php running in a docker container with the folder mapped for read and write.

in a folder:

drwxrwxrwt 2 root     root           1160 May 21 11:08 ./

i have a file:

\-rw-rw-rw- 1 www-data www-data          9 May 21 11:06 queueFile.txt 

this file, in my mind, has access for read and write by anyone.

If the file was created by php, my normal user will not be able to write to it, chmod it or remove it.

If the file is created with samba, then php can not append, chmod or write to it.

it is not listed as locked by samba.

read access is granted ok.

I am loosing it a bit, that file rights seems to have become ghosts that just makes up their own rules.

Any helpful suggerstions?

the folder is mounted as a memory filesystem but i had similar problems with the normal file system:

tmpfs on /uf/proxy type tmpfs (rw,relatime,size=262144k,inode64)

/dev/xvdb on /uf type btrfs (rw,relatime,ssd,space_cache=v2,subvolid=5,subvol=/)

I also tested to run the php script as root from CLI but it still say I do not have access to write to the file. So it seems its not docker related...

tried opening it in nano as root and add some text, not allowed to save it.

fuser queueFile.txt

gives an empty response

smbstatus|grep query

gives an empty response

smbstatus|grep proxy

gives:

498026       1001       DENY_NONE  0x100081    RDONLY     NONE             /uf proxy   Thu May 21 15:08:03 2026

i am new to ubuntu and try to install ofbiz and one of the steps are to "run the gradle". In the terminal it say download failed - check the logs and fix the problem. Where do i see the logs and then how do i fix such problems

What's working thanks to @daniel-t:

#!/bin/bash

sudo XDG_RUNTIME_DIR="/run/user/$(id -u admn)" pw-play -p /usr/share/sounds/Yaru/stereo/desktop-login.oga

# or

XDG_RUNTIME_DIR=/run/user/1000 pw-play -p /usr/share/sounds/Yaru/stereo/desktop-login.oga

exit;

OS: Ubuntu 26.04 Resolute

Desktop: MATE Desktop Environment 1.28.2

Installation: Fresh (Not upgraded from any previous version). Installed Ubuntu Server 26.04 and then installed MATE Desktop on it.

Note: Sound is working just fine. I can play any audio or video file through VLC just fine.

I can even play sound from a terminal with the following command just fine:

pw-play -p /usr/share/sounds/Yaru/stereo/desktop-login.oga

And still, I get this error:

error: pw_context_connect() failed: Host is down

When the same command is run from a script with sudo:

#!/bin/bash

sudo -u $USER pw-play -p /usr/share/sounds/Yaru/stereo/desktop-login.oga;

# or

pw-play -p /usr/share/sounds/Yaru/stereo/desktop-login.oga;

# or

sudo -u admn XDG_RUNTIME_DIR="/run/user/$(id -u admn)"  pw-play -p /usr/share/sounds/Yaru/stereo/desktop-login.oga;


exit;

Output:

Any help is greatly appreciated.

Applications could be launched in 25.10 from the desktop. After upgrading to 26.04 all the desktop shortcuts have a red cross and at right-click there isn't any allow launch option anymore. The files do exist and were unmodified. Do you have any suggestion for the root cause of it or how to fix it? Changing files chmod to +x does not fix it, but all files have an x bit set.

The desktop files are in ~/Desktop and when opening the item from the desktop with another application (i.e Gedit) the file can be edited.

I'm running Ubuntu 26.04 LTS, 64-bit, Linux 7.0.0-15-generic, gnome version 50.

And using an NVIDIA GeForce RTX 3060.

I downloaded and installed the new Ubuntu, onto a newer computer. Installed Steam, and was met with the message:

"32-bit NVIDIA driver files were not found on your host system. It's best you install them for the best experience."

It then gives some terminal commands.

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libnvidia-gl-595:i386

Enter the commands in that order and it gives me this response:

Starting 25.10 Ubuntu (Gnome) installer could install alongside Windows even with Bitlocker ON, if there is a freespace already.

But today when I installed 26.04, there was no Grub installed in EFI partition (as I checked later through Windows). So there was no way to boot into the Ubuntu, the Bitlocker screen came up. I didn't face this issue with 25.10 when installing alongside Windows with Bitlocker ON.

Should I try Kubuntu 26.04 now? Although they still have Calamares, not Flutter installer, can it work?

I’m trying to diagnose a persistent read-only filesystem problem on an HP desktop and would appreciate ideas on what to test next.

System details:

• SO: Dual boot with ubuntu 18.04 and windows 10 on a HDD
• Machine: HP ENVY 750-500 Desktop PC series
• Motherboard: HP board ID 2B36
• BIOS version: 80.11
• BIOS date: 2015-04-01
• SATA controller: Intel 9 Series Chipset Family SATA Controller [AHCI Mode]
• Kernel driver: ahci
• Storage setup: SATA SSD connected internally

The SSD I tested is:

• Model: Crucial CT500BX500SSD1
• Firmware: M6CR072
• Capacity: 500 GB
• Interface: SATA III 6.0 Gb/s

Problem

After installing Ubuntu 24.04 on the SSD, the system would intermittently remount the root filesystem as read-only. The symptoms included:

• sudo touch /tmp/testfile failing with Read-only file system
• sudo apt update failing because it could not write to /tmp, /var/cache/apt, or /var/crash
• The system sometimes booting, but later behaving as if the root filesystem had become read-only

What I tested I tested the SSD and several different SATA cables:

• one brand-new SATA data cable
• two other data cables already in use with HDDs
• different SATA power cables
• disconnecting a HDD and reusing its SATA cables

Filesystem checks From a live USB, I ran:

sudo fsck -f -n /dev/sdc2

The result showed no filesystem errors. The output completed all passes without reporting problems.

SMART checks I installed smartmontools and ran:

sudo smartctl -a /dev/sdc
sudo smartctl -x /dev/sdc
sudo smartctl -t long /dev/sdc

Important results:

• SMART overall-health: PASSED
• Extended self-test previously completed without error
• No reallocated sectors
• No pending sectors
• No offline uncorrectable sectors
• But UDMA_CRC_Error_Count is 731

The full SMART output suggests the SSD itself is not failing in a classic way, but the CRC error count makes me suspect SATA link or motherboard-side issues.

Other observations

• The SSD benchmarks looked normal for a SATA SSD.
• The system is running in AHCI mode.
• I don’t fully believe all SATA cables and ports on the board are bad, so I’m wondering whether this could be a motherboard, BIOS, power, or controller issue instead.

My main question Given that:

• two different SSDs showed similar read-only behavior,
• multiple SATA data cables and power cables were tested,
• fsck found no filesystem corruption,
• SMART passed but UDMA_CRC_Error_Count is high,

what would be the next best step to isolate whether the problem is:

• the motherboard SATA ports,
• the PSU / SATA power,
• BIOS/firmware,
• or something else?

Would updating the HP BIOS be worth trying on this system?

Thanks in advance.

I have updated my Ubuntu from 25.10 version to 26.04, I received some error dusring the installation about the kernel.

At the first start I had a kernel panic error, I solved it starting my PC with the previous kernel version then I provided the following commands:

 sudo update-initramfs -u -k version

Now I can boot with any problem my PC with the latest kernel available 7.0.0-15.

But I think there is a problem, if I try to update my system via terminal this is what I have:

Same issue

I had to rebuild my FLASH disk after a rebuild that used Ubuntu Server 24 first (because the DVD no longer contains the full Ubuntu Desktop configuration). Neither logout/login nor full reboot after the described removals works.

The previous successful answer was to rm -Rf ~/.cache/thumbnails/fail

from Ubuntu 24.04 File thumbnails not visible on desktop

That no longer works for me.

I sincerely hope the only workable answer now ISN'T starting from Ubuntu 22.04 and doing an online full system rebuild.

Since updating to Ubuntu 26.04 on my laptop, I've been having an issue where the screen just goes black after Ubuntu boots up. I see the boot animation, but as soon as I reach the login screen, the screen goes black. When I connect a second monitor, I can see that everything works fine on it. I’ve already found a workaround to reactivate the primary screen: if I briefly close the laptop and then open it again, everything suddenly works as it should. I generated a GPU log of the startup. You can see that after 9 seconds, the graphics card tries to communicate with the screen and apparently fails. A clean install did not fix the problem. Does anyone have any idea how to fix this?

I've been using WSL on my work laptop and just recently I started getting store space errors, which is surprising because I have a 1TB SSD. I checked the storage settings and it shows Ubuntu 22.04.5 taking up 803GB of space, which is insane (see screenshot). On further examination, it shows that the app takes up 324 MB while the data is taking up 802 GB. I tried the repair and reset options, but nothing happened. I am unable to install any more applications on my PC because of this.

When going through the menu, I only see an option to back up the profile for Thunberdird whereas I want to backup e-mail. Version:

nicholas@mordor:~$ thunderbird --version
Thunderbird 115.4.1
nicholas@mordor:~$ 
nicholas@mordor:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04 LTS
Release:    22.04
Codename:   jammy
nicholas@mordor:~$ 

From tools how is the backup e-mail option selected?

I set USB provisioning_mode to unmap to allow TRIM discard for an external USB SSD that supports TRIM. The system reverts to provisioning_mode full after reboot. TRIM works great with provisioning_mode set to unmap, so that I can manually TRIM a partition or entire drive when I want to. I have more than one etc/udev/rules.d files - 10-uas-discard.rules, 10-trim.rules, 50-usb-ssd-trim.rules & 90-usb-discard.rules - all contain the exact same data - ACTION=="add|change", ATTRS{idVendor}=="174c", ATTRS{idProduct}=="55aa, SUBSYSTEM=="scsi_disk", ATTR{provisioning_mode}="unmap"

Is there any way to prevent this? Am I missing something?

I use a laptop connected to an external monitor with 18.04, and don't use the laptop screen at all.

It generally works great but the custom splash screen I added with Plymouth shows up when I boot, sized for my laptop screen, not the monitor, and it looks really tacky.

I've spent several hours on this but I don't have the proper knowledge to diagnose the problem. How can I scale up or resize the splash screen?

I just bought an Acer K272HUL 27" monitor capable of 1440 resolution to use with a 4k laptop running Ubuntu 18.04 and a Nvidia 960M GPU. I followed the directions here(I needed to use cvt - r since this model blanks)

https://wiki.archlinux.org/index.php/Xrandr#Adding_undetected_resolutions

Everything seems to work great. I get 2650x1440 on the Acer. My problem is how to make this permanent? The instructions say to create an entry in /etc/X11/xorg.conf.d/10-monitor.conf but I don't think I have that file under Ubuntu 18.04. How do I make this resolution option permanent?

These are the files/directories under /etc/X11/ ` app-defaults rgb.txt Xreset.d Xsession.options cursors xinit Xresources xsm default-display-manager xkb Xsession XvMCConfig fonts Xreset Xsession.d Xwrapper.config

I would like to understand what a masked service is and how to unmask it if need be.

I have been trying to start PostgreSQL on Ubuntu 16.04-LTS using the command

systemctl start postgresql.service.

Both as a user with administrative privileges, as well as root respectively.

Unfortunately, I got

Failed to start postgresql.service: Unit postgresql.service is masked.

printed in both scenarios.

I have a lovely mount: unknown filesystem type 'ubifs' error with Ubuntu 14.04. What package provides this functionality?

It should be included in some previous versions of Ubuntu. The mtd-* packages are not helping.

I ordered a new computer with Windows 8 to test before rolling out. It arrived with Ubuntu 12.04. Rather then just send it back, I decided to check it out first as I think the system is probably much better than the MS options. However, try as I might, I cannot get a PPA set up. I'm trying to install Pinta-Paint but can't find the line to copy into the software centre. Please could someone point me in the right direction.
