I am trying to install clang but ubuntu keeps saying the package isn't found or hits me with "This script must be run as root!", which wasn't mentioned in an article that seemed to address the issue. It recommended that I paste a line of test to install clang and then hit enter to confirm installation. Then it also gave a way to check if clang downloaded successfully. Unfortunately, the solution didn't work for me. I also tried changing the version number as someone else mentioned that it worked for them. However, it also didn't work when I tried it.

Please help me, ai can not solve it, I need a human like you.

I (with the guessings of GEMINI deep research) can not get Ubuntu 26.04 LTS to boot unless I hit 'e' at the boot menu to modify the Linux line to {nomodeset acpi=off}. I flashed the Ubuntu ISO to a PNY 32GB flash drive using {rufus}

After dozens of failed attempts and countless hours to install {ubuntu} to a {ssd}, I plugged the SSD into a laptop in a ssd enclosure via usb and successfully installed 26.04 into the HP laptop but never booted ubunto OS in the HP laptop . Then i installed the SSD directly onto the asus MOBO. The problem is that I can not make full use of the 24GB VRAM because i can only boot into the 26.04 with that {nomodeset acpi=off} to force ubuntu to boot with ancient drivers VGA/etc. A normal boot ends up in a solid black screen everytime after the Asus splash screen {unless I click esc and type 'e' next to the ubuntu option}

Ubuntu 26.04 LTS is not meant for old workstations like this.

System: It was built in 2018 so it's old

MOBO: {ASUS PRIME X299-DELUXE II}

CPU: {Intel Core i9-9980XE (18 Cores, 36 Threads)}

Video: {NVIDIA Titan RTX (24GB VRAM)}

Drive: {Samsung SSD 970 EVO Plus 2TB}

BIOS: {4301}

Intel firmware: {Intel ME firmware 11.12.98.2655}

Install media: {PNY 32GB USB 3.2 flash drive}

Install file: {ubuntu-26.04-live-server-amd64.iso}

please and thank you immensely

I have confirmed that this is not an issue with other OSs and cannot find any solution. The mic works fine on Windows and Fedora. Extreme pulsing static only in Ubuntu.

For my first time I installed kubuntu with crypt option with a Live USB. It was automaticaly done creating a lvm partition and luks crypted it. It worked fine, thanks.

I cautched cpu load (Plasmashell process) problens on kubuntu 25.10 ; and then tried to early upgrade to 26.04. Not a good idea, or I maked mistakes. I realy have to reinstall from live USB (that works fine without cpu overload).

Before, I always had setup /home partitions. It is the first time I have to reinstall without this security. Inside luks container, I worked on lvm to separate /root and /home (yes I maked backups before) ; but in the installer I did not find anyway to reinstall on the /root partition I made. It is going tu take all the luks volume

Do I have to understand that installing in luks partition does not let us the choices off partitions to use ; or I did not find the way to do that ?

Even If I loose everything for this time ; I would like to use a separate /home partition in the luks container for the next reinstallation in some years. How is it possible ?

New person here. Loaded Ubuntu 26.04 Desktop today. Checked for Windows 10 to be deleted. I took a break and when I came back, the PC still booted to WIN 10 and I had to use the Flash drive to get into Ubuntu. The motherboard battery needs replaced, could this have caused the issue?

This is similar to How do I make F13 not open settings? (Ubuntu 24.04.2 LTS), but I'm in KDE now instead of GNOME, and I now have a physical F13 key on my keyboard. Every time I press it, Settings opens. This time, I don't really know what to try. How do I stop this nonsensical behaviour?

Please help me here. I am running at home old Linux server. Recently figured out that it's services (photo sharing etc) is not working.

Checked it out and seems something went wrong with internet connection.. Etherner isstill working as I can connect to server via PuTTY soft.

I have a brand new fresh install of Ubuntu 26.04 on a Dell laptop. Ctrl + . ("control period") opens up the emoji picker. I would prefer to reserve Ctrl + . for other functions, for instance it is the default keystroke for my password manager to fill in passwords in a web browser; GNOME seems to override this and the emoji picker pops up. I cannot find the setting to disable the default mapping (I would like to disable emojis completely if possible). I have looked in keyboard settings and ibus-setup. Suggestions?

In Dolphin, I set “Remember display style for each foler”, because I want, say, the Images folder to use “Icons” view, whereas most other folders to use “Details” view. However, this setting doesn't just apply to things like that, and instead applies to other things like “Show Hidden Files” and “Hidden Files Last”. How do I tell Dolphin that I want options like these to apply globally?

For the past 1–2 weeks, I haven't been able to install updates via VPN. I also can't access https://launchpad.net via VPN anymore: “Error: connection refused.”

I have no issues using my ISP's IP address. What's going on? Are VPNs now permanently blocked? I've tried several different ones, and I can't access the site even with the Tor Browser.

Offline PC: Ubuntu 24.04.4

sudo apt update (Online only at this point)
sudo apt install apt-offline_1.8.5-1_all.deb (Online only at this point)

Online PC: Ubuntu 24.04.4

sudo apt update
sudo apt install apt-offline

I tried to install various packages on the offline PC using apt-offline, following instructions I found online.

However, when I transfer the sig file generated on the offline PC to the online PC and try to download the packages as instructed, I get the same message for every package, and the download fails, creating a zip file with 0 bytes.

VERBOSE: http://archive.ubuntu.com/ubuntu/pool/main/m/mozc/mozc-data_2.28.4715.102%2bdfsg-2.2build7_all.deb - 403 - Forbidden

I can download the corresponding deb file by accessing this URL directly from my browser (Firefox) at online PC.

I don't understand why downloading with `apt-offline get *.sig --bundle *.zip` results in a 403 error, even though I can download it from the browser.

How can I obtain the zip file using apt-offline?

Both my offline and online PCs are mostly in their original Ubuntu 24.04.4 state, except for enabling the firewall.

I haven't touched any repository settings. The image used to install Ubuntu 24.04.4 was "ubuntu-24.04.4-desktop-amd64.iso," which was downloaded from the official Ubuntu website.

Both events are scheduled to take place around May 8, 2026.

The following are the details of the execution in the terminal on the offline PC.

Any advices how to debug the issue?

For KDE Plasma SDDM (all names intenionally given here to allow search hits)
The default greeter "maya" uses a tiny CONDENSED "Font" and cannot be set to anything else by normal means, e.g. in /etc/sddm/font.conf .

Now, this looks awful on anything with a slightly modern resolution.
So a change is "urgent"; how to do it?

This appears to be disregarding "highdpi" settings and the scaling referenced in many postings. Here we are at the FONT setting, disregarding SCALING.

Tiny image due to restrictions:

I use this to start a script via double click :

if [[ ! -t 0 ]] && [[ -x /usr/bin/konsole ]]; then
    /usr/bin/konsole -e "bash -c \"$0 $*; read -s -p 'Press enter to continue...'\""
    exit
fi

Via double-click it does open the script and I expect a Terminal will be opened before the respective script will be started.

But sometimes it works, but sometimes not ?

Any idea to improve it ?

I decided to upgrade from Ubuntu 25.10 to 26.04 today and everything has gone well apart from I now get the following issue when starting any VMs I have, using virt manager:

This is a weird problem. I have two Ubuntu servers. One, running Ubuntu 25.10, is fine, no issues, the other one runs Ubuntu 24.04.4 and is the host for my Apache webserver and postfix/Dovecot email server.

After the last NetworkManager update last week, the use of network aliases no longer work for Ubuntu 24.04.4 server.

For instance if I want to connect to my webserver, www.abcvde.net that resides on the 24.04.4 server, I get a "Destination Host Unreachable." Nor can I use the IP address (192.168.0.22), it times out. However, if I use the localhost alias or its IP, it works. Using the server's own IP, 192.168.0.11 fails as unreachable.

Pinging the alias name, BBB fails, as does pinging its IP. However, I can ping other PCs/servers in my home network using either IP address or the alias.

What is more puzzling, since this occurred at the same time, I'm no longer receiving emails. I believe there's a connection but don't see how. I only have one server set up as a email Dovecot Imap/POP3 server and postfix so I can't just redirect the incoming email packets to another server. Outbound emails work, no issue. Email app is Thunderbird.

I also checked to see that the firewall is off. I'm behind two other firewalls and a NAT. A firewall isn't needed. The router is TP-Link.

Thoughts? Ideas?

Update. Checking with my external mail gateway, mu inbound emails are beging rejected at my end with "400 Network error: Could not connect: No route to host." The gateway confirmed my DNS entries are correct.

As an aside, I can connect to other servers in my private network from outside.

So, some thing happened with that update.

I updated my system from 24.04 LTS to 26.04 LTS. I wanted just to update, not upgrade the Ubuntu version. Don't ask ... I was very stressed and copied some commands without thinking about. Stupid - I know.

My problem is, each time I try to "sudo apt upgrade" I get this error:

I'm new to Linux (about 6 weeks) and have been testing multiple versions of Linux on my NUC which resulted with an SDD with three OS partitions. The sequence of installation was:

1. Windows 10
2. Ubuntu 
3. Winux

My goal: I want to remove Winux from the boot list as I migrate away from Windows and embrace Ubuntu.

My Situation: I've read other posts about multiple OS's and the removal of 1, but nothing seemed to match what I have unwittingly created.

In the PC's Intel BIOS, there are only two entries:

Windows Boot Manager
Winux 11

From Ubuntu using efibootmanager I have the following boot entries:

BootCurrent: 0001
BootOrder: 0001,0000,0002,0003
0000  Windows Boot manager
0001  Winux 11

When I select Winux 11 from the first boot list presented, I see a completely different list of boot options:

Winux 11 GNU/Linux
Advanced Options for Winux 11 GNU/Linux
Memory test (memtest86+x64.efi)
Memory test (memtest86+x64.efi, serial console)
Windows Boot Manager (on /dev/nvme0n1p1)
Ubuntu 24.04.4 LTS (24.04) (on /dev/nvme0n1p7)
Advanced options for Ubuntu 24..04.4 LTS (24.04) 
UEFI Firmware Settings

Now to add more confusion ... from Ubuntu when I list it's boot list:

awk -F\' '/menuentry / {print i++, $2}' /boot/grub/grub.cfg

I get yet another different boot list:

0 Ubuntu
1 Ubuntu, with Linux 6.17.0-23-generic
2 Ubuntu, with Linux 6.17.0-23-generic (recovery mode)
3 Ubuntu, with Linux 6.17.0-19-generic
4 Ubuntu, with Linux 6.17.0-19-generic (recovery mode)
5 memtest86+
6 Memory test (memtest86+x64.efi, serial console)
7 Windows Boot Manager (on /dev/nvme0n1p1)
8 Winux 11 (24.04) (on /dev/nvme0n1p6)

My Concern: I'm confused with the various boot lists and their differing sequences. So using any of the other articles I've read didn't give me confidence to just "try" one of their methods. I don't feel like I could afford to lose my Windows system just yet ... although EOL is coming for it soon!

I have an even older dedicated Linux machine with a GTX-560 on an old ASUS Maximus IV motherboard with an Intel i7-2700K, and after upgrading to 26.04 it still feeds two monitors just fine. (Might be a clue here?); (I am not a gamer, hence the continued use of the GPUs, they are fine for work.)

On my MSI 399 Pro Carbon, 24 thread AMD, with the 760, I have tried to use the 470 Nvidia driver to no avail, and I went back to the recommended Nouveau. Is there a legacy procedure of any kind or software mod to get two screens again on my best machine? Incidentally, the card runs both monitors on the Windows O.S. different drive, both drives are NVMe.

E.T.A.: Oops, (not 'USB'), the monitor feeds are DVI and HDMI direct from GPU, no vid on motherboard. Mea culpa...

I am unsuccessful in establishing a RDP remote login connection to Ubuntu 26.04LTS.
I followed the instructions here. It is a fresh installation of Ubuntu.

As a client I use Remmina on 24.04. Authentication works, but the screen remains black, with no error. Please see screenshot. The top border of the screen shows some "colors" when looking at it exactly.

In contrast, RDP Remote Desktop sharing works. Connection from other client devices equally do not work.

P.S. I did some further testing today, using a Windows 11 machine to connect. In fact, the Windows RDP client connects and logs in successfully to the Ubuntu 26.04 machine. So it is likely to be Remmina having some issues here?!The Windows RDP client only gives a warning about encryption:

Remmina logs as follows:

The latest upgrade few days ago broke my desktop private key loading stack, in the sense that I have a passphrase protected private key, and I am used to SSH login to other sites with that key. The "normal behaviour" is that after any reboot Gnome ask your host password and somehow with that password it can open the private key and the SSH works normally. Now, I still have the pop-up asking my user/host password (not the passphrase), but the SSH login attempt just do nothing. I need to manually add the key with ssh-add ~/.ssh/id_rsa, and then it works.

Am I the only one with this strange behaviour ? Any workaround to get it back that the login "open automatically" the private key ?

I have a computer running Ubuntu 24.04 LTS desktop where I have QEMU/KVM running. One of the guest OS is Windows 11. This VM has secure-boot on as required by Windows. The secure boot certificates originally issued in 2011 will expire next month. The new certificates were issued in 2023.

The above page shows a table of expiring certificates:

| **Expiring Certificate**                  | **Expiration date** | **New Certificate**                  | **Storing location** | **Purpose**                                          |
| ----------------------------------------- | ------------------- | ------------------------------------ | -------------------- | ---------------------------------------------------- |
| **Microsoft Corporation KEK CA 2011**     | June 2026           | Microsoft Corporation KEK 2K CA 2023 | Stored in KEK        | Signs updates to DB and DBX.                         |
| **Microsoft Windows Production PCA 2011** | Oct 2026            | Windows UEFI CA 2023                 | Stored in DB         | Used for signing the   Windows boot loader.          |
| **Microsoft UEFI CA 2011\***              | June 2026           | Microsoft UEFI CA 2023               | Stored in DB         | Signs third-party boot loaders and EFI applications. |
| **Microsoft UEFI CA 2011\***              | June 2026           | Microsoft Option ROM UEFI CA 2023    | Stored in DB         | Signs third-party option ROMs                        |

It looks like my VM is not using the new certificates. When I check the secure boot status from within Windows guest, it says:

Secure boot is on, but your device is using an older boot trust configuration that should be updated. There is not yet enough data to classify your device for automatic update.

This page says if I see this message then:

Your device might need additional validation before the update can proceed automatically. Visit aka.ms/getsecureboot for more information.

The link takes me back to the original page linked above.

This made me think Windows update failed to work with QEMU's UEFI firmware called OVMF.

The XML tab of the Overview section of the Virtual Machine Manager shows in part:

    <loader readonly="yes" secure="yes" type="pflash">/usr/share/OVMF/OVMF_CODE_4M.ms.fd</loader>
    <nvram template="/usr/share/OVMF/OVMF_VARS_4M.ms.fd">/var/lib/libvirt/qemu/nvram/win11_VARS.fd</nvram>

The files OVMF_CODE_4M.ms.fd and OVMF_VARS_4M.ms.fd have the modified date of December 10, 2025. The file OVMF_CODE_4M.ms.fd is linked to OVMF_CODE_4M.secboot.fd in the folder /usr/share/OVMF/.

I looked at the OMVF UEFI configuration menu and couldn’t find anything regarding the secure boot certificates or anyway to add new ones.

Here is the Windows 11 System log:

My searches have led to some solutions for Red Hat, and Proxmox, but nothing specific to Ubuntu.

From the Linux perspective most solutions refer only to updating to the Microsoft UEFI CA 2023 certificate. I have not seen anything on how or if one should update the three other certificates expiring in 2026 when running Windows in a VM.

Q: How do I make sure that the OMVF is using all the secure boot certificates from 2023 so that Windows 11 works as expected beyond June 2023?

Thanks

I recently installed Ubuntu 26.04 and I noticed that the thumbnails for my comics aren't showing in the Files file manager. I tried installing different thumbnailers, but nothing seems to work. Instead it just shows the default Ubuntu document icons.

I do not have Evince or mcomix installed. I'm using the default document reader that comes with Ubuntu 26.04.

I get this error when I try to change the Ubuntu desktop settings in Ubuntu 26.04 LTS. I have uploaded the error message. If there is any solution please share.

I'm experiencing an issue with my earbuds on Ubuntu 25.04 and I am on the latest kernel version 6.14.0-32-generic and the earbuds I am trying to connect to is Redmi Buds 6 and that issue not only happens on Ubuntu but Other Linux Distros like Arch Linux, Pop!_Os and Fedora. I am currently using pipwire.

Unlike normal bluetooth connection, when the bluetooth is connected there will be a sound that notify the state of being connected but now I there's no notification sound from earbuds and I have tested with other operating system like old arch Linux kernel and Windows they both works.

I am able to search my bluetooth device. I am able to connect via bluetoothctl.

I am actually malding right now. I've just set up Input Remapper to map Caps Lock to F13 so that I can use it as another button in games. In Windows, I would do this with Razer Synapse (also remapping Fn+Caps back to Caps Lock) and it would work fine, but it seems I have another reason to dislike Razer.

Anyway, now everytime I press F13 (Caps Lock), it opens Settings. I tried removing the useless bind by setting /org/gnome/settings-daemon/plugins/media-keys/control-center-static to [''], but that didn't work. I tried remapping key 179 (previously XF86Tools) to F13, but that also didn't work. Of course, Google's as useful as it always is in these situations, so I'm out of ideas. How do I stop this from happening? Bonus if you can tell me how to map my Synapse keys on Linux as well.

Edit: I also tried mapping key 66 (Caps Lock) to F13 via xmodmap (below code), and that doesn't open Settings, but now it both presses F13 and engages Caps Lock. What?

keycode  66 = F13 F13 F13 F13 F13 F13 F13 F13

Since the update yesterday (yes, the linux update), eclipse denies me to run even the most simple helloworld:

I tried to update the JRE (and JDK):

• window -> preferences -> java -> installed JREs. I could check: java-8-openjdk-amd64 (which is currently) or java-11-openjdk-amd64.
• window -> preferences -> java -> compiler. Compiler compliance level is set to 1.8 (it doesn't know java 11. It does know java 9.)
• window -> preferences -> java -> Installed JREs -> Execution Environment. When clicking on JavaSE-1.8 in the left list, 2 options appear in the right one: java-8-openjdk-amd64 and java-1.8-openjdk-amd64. First one is checked. (But I don't think, that matters, because these should be the same.)
• I tried to update eclipse. (No updates available)

So anything is set to Java8. Why does the error still occur?

Btw, some of my projects (the helloworld including) are marked with a red exclamation mark, but the error appears in any project, not in these only.

• I use XUbuntu 18.04 now (before the update anything worked fine)
• I use eclipse Photon
• I use java standard API only
• I use git and the eclipse git plugin

i am running a program on ubuntu linux server at the background using setsid <program name> normally, the programs prints its output in the terminal but i want to see the output in a file, like a log file even while the program runs at the background. How can i achieve that?

Here is:

I try to find in gnome-tweak-tool, but I have no luck. I'm using Gnome Shell v3.8.3 on Ubuntu Gnome 13.04.
