I am using Ubuntu 24.04. I'm afraid some hacker might have tampered with my repositories.

All I did was search for the name of a package that I would like to download in the App Center, and this message appeared:

The software is not from a trusted source.
Do not install this package unless you are sure it is safe to do so.  

It appears in all .deb packages from the official Ubuntu repositories.

The funny thing is that my default language in Ubuntu is Portuguese, so why did this message appear in English?

I did not install any unknown fonts from the repositories, and it's not snap

The message that appears when trying to install it is

The software is not from a trusted source.
Do not install this package unless you are sure it is safe to do so.

In summary: I find a program in the software center. I click to download it. The above message appears, and then it asks for a password to install.

The output of the apt update terminal is:

To add an application to my favorites or ensure the icon is visible in the GNOME Shell application dock, I need to enter the StartupWMClass value in the desktop file. Sometimes this is simple, such as recoll but other times it is long and complex such as com.transmissionbt.transmission_66306_105514770. When it is long and complex I would like to be able to copy it from the Looking Glass interface. However I am not sure how to do this. There is a clipboard icon next to the crosshairs (visual picker) icon in the upper-left corner but it does not appear to save any text to the clipboard. This copy function was found to be working in 2021, so I figure I must be doing something wrong. How can I copy the wmclass value for a window in Looking Glass?

I'm using the latest LTS version of Ubuntu (24.04).

I’m looking for a good alternative to Internet Download Manager (IDM) on Ubuntu.

I’ve already tried Xtreme Download Manager (XDM), and it works fine for normal downloads, but I’m having trouble when it comes to downloading videos from YouTube — sometimes it doesn’t detect videos at all or fails to download them.

So I’m wondering:

• What is the best download manager on Ubuntu that feels similar to IDM?

• Is there any tool that reliably supports downloading videos from YouTube?

• Should I stick with a download manager like XDM, or switch to something else (like command-line tools)?

I’d prefer something with:

• Good browser integration (especially Firefox)

• Stable video downloading support

• Easy-to-use interface (if possible)

Any recommendations or setups that worked well for you would be really helpful.

Thanks!

I know this question was asked 1000000n times and it was answered 1000000 times. Nevertheless none of these solutions works for me. I installed Ubuntu 24.04 as Virtual Machine in Hyper V on my laptop. Laptop has resolution: 3456x2160. I completed initial setup and everything works fine now. But I still cannot change resolution of the Virtual Machine higher than 2560x1600.

On Linux:

• I set: GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash video="hyperv_fb:3456x2160" in grub
• I run: update-grub

On Windows:

• I run set-VMProcessor -VMName "name-of-my-machine" -ExposeVirtualizationExtensions $true
• I run Set-VM -VMName "name-of-my-machine" -EnhancedSessionTransportType HvSocket
• I run set-vmvideo -vmname "name-of-my-machine" -horizontalresolution:3456 -verticalresolution:2160 -ResolutionType Single

And still when I connect to this VM it's open with max resolution as 2560x1600. I imported this VM on my desktop machine with 4K monitor and I have the same result - max screen resolution of VM is 2560x1600.

I run virtual Ubuntu on the same laptop before using Hyper V. I don't remember exact version. Maybe it was 22. An I was able to use the full screen mode. But now it is limited by 2560x1600.

So is there any special solution for this issue for virtual Ubuntu 24.04 in Hyper V environment?

I connect to the internet at public sites, usually my local library, which involves a network login page.

My problem is that before that can happen, the network xfinity often hijacks the login process by connecting itself to my laptop.

How can I permanently ban xfinity network from connecting to me. I use Network Manager on Lubuntu 24.04

Until now, Snap was used in Ubuntu to install specific applications, such as Firefox, but those applications and snapd could be removed (and the applications could be replaced by packages, in some cases, such as those from Mozilla, or with Windows apps running in wine, such as 7-Zip).

Online, I've read that various components intrinsic to Ubuntu 26.04 are using snapd, and that it no longer can be removed simply. Is that the case, or is it feasible to remove snapd, still?

After connecting a new Bluetooth keyboard to my desktop computer with Ubuntu 24.04.4 LTS, I removed the new keyboard from the Bluetooth devices screen by telling Ubuntu to ignore it (by mistake, I now see). Now it's ignoring it and won't discover it anymore.

What would you suggest I do to fix my mistake and let it discover the new new keyboard again?

Just did a fresh install of Ubuntu 24.04.4 LTS and there is no HDMI sound out device listed to select for sound. Only "Digital output (S/PDIF) - USB Audio and HID" and "Analog Output - USB Audio and HID".

Did a bunch of digging, and tried any potential solution I could locate from updating intel drivers, to installing/using pulseaudio, and any other troubleshooting steps I could find. Even swapped out HDMI cable for a new one.

Also, for whatever reason, I can't get a command line listing of devices.

Still not seeing HDMI as a sound output option and sound out remains elusive.

At wits end.

Note that the HDMI audio works just fine for other devices connected to the monitor.

I have created a simple Java application (Spring MVC with one REST service) and I need to perform high-load testing after deploying it on Ubuntu 24.04.2 LTS.

I have already done some optimization of both the application and the operating system, and I am now achieving roughly the desired throughput and latency during testing. However, I’m not confident that my testing approach is entirely correct.

I understand that to simulate more realistic traffic, requests should be generated from multiple client machines. In my case, I only have one client (my laptop) and one server (another laptop), connected via a 1-meter Ethernet cable.During testing, I generate a large number of HTTP requests, and the packet flow for each request looks like this in Wireshark (see screenshot below. Total packets size is 1049bytes for 1 http request. I also use virtual IPs to workaround limit with ports).

For now, I’ve managed to achieve throughput of up to 100,000 requests per second(average wall clock time since Java HttpClient::send is invoked and after response synchronously received), given that both laptops use Ethernet cards with a maximum speed of 1 Gbps.

At a high level, I understand the TCP communication between one Ubuntu host and another as shown in the diagram (see screenshot).

I would like to also point out that I understand the difference between parallel and concurrent requests well.

My question is:

Is there anything in the Ubuntu (Linux) kernel—such as buffering, caching, or other optimizations—between receiving the initial TCP SYN packet from the client and sending the final response, that could artificially increase the number of requests per second when testing from a single client?

In other words, if I were to generate the same total load but distribute it across 10 different client machines, would I observe significantly lower throughput and why?

Or more specifically:

Are there any optimizations in the network stack that depend on using the same client IP address and port?

For various reasons we might need to move from FreeBSD (VM-ware) to Ubuntu (KVM).

As we use a lot of large tables with ip addresses stored in textfiles, which we load into FreeBSDs packet filter (pf), we are looking for similar solutions in Ubuntu, if there are any.

The text files contains over 900 000 ip adresses in total, to block.

Is this possible to achieve in Ubuntu with IP-Tables?

If so, what's required and are there any examples?

We are waiting for Ubuntu 26.04 LTS (Resolute Raccoon), and it's going to be shell based web and DB server.

Thanks,

Is it possible to build a user-land apparmor profile? I have an Electron app, and a bunch of users that prefer installing their apps in their home rather than in the root. Unfortunately, running the Electron app requires an apparmor profile because of the sandbox, and I was not able to find a way to build such a profile in user-space, I necessarily have to install something in /etc.

Is it correct that it is basically impossible to install an Electron app without admin access on Ubuntu? :(

I am using Ubuntu for some time, but I am not expert in Linux. I installed FreeFileSync on Ubuntu 24.04 LTS. After the installation I could see many folders on my desktop. How to remove these folders?

I have more than one WiFi adapter installed on my machine running Ubuntu 24.04. They're always shown in the same order in WiFi settings no matter which one is actually connected. See the picture below.

Is there a way to change the configuration so that the WiFi adapter that is connected to the WiFi network is displayed first in Settings?

I'm trying to install Ubuntu 24.04 (latest) on Lenovo ThinkPad L15 Gen 3 (AMD), but I can't. I first had Windows 11 and no usb, so I tried grub2win and unetbootin, both failed. I found a usb stick and ran:

sudo dd if=ubuntu-24.04-desktop-amd64.iso of=/dev/sdX bs=4M status=progress oflag=sync

I entered BIOS and changed secure boot to OFF. I inserted usb stick and installed by erasing disk. All seems fine. But after restart into Ubuntu I remove the usb stick and all buttons, all icons, vanishes. i cannot open any programs.

I force power off and back on. Now Windows 11 and Unetbootin comes up. I restart and enter boot menu. i select Ubuntu, but the screen just flashes, nothing.

This link says my computer is certified to run Ubuntu https://ubuntu.com/certified/202204-30189 so why can't I?

UPDATE:

The Ubuntu installer installed on the usb stick, not on the sdd.

Whenever I copy a text or image and try to paste into an app (search bar or anyc place), the app I want to paste into freezes and the only solution is to force quit that app. Once this problem starts the only way to to stop it temporarily is to restart Ubuntu. Are there any solutions to this?

I volunteered to set up a PC for my niblings to learn to code and so on. Windows sucks and I wanted to start the kids off right.

I had it installed and running fine, was up to installing Minecraft and Blender, but the WiFi was bad, so I moved the setup from my bedroom floor to the lounge by the router. After that turning it on left only a blank screen. I plugged the HDMI directly into the GPU and that gives me the GRUB menu, but when I select boot Ubuntu it doesn't work, and boot in recovery mode gives a wall of text that I don't understand and nothing else.

The only thing on the screen that appears to me to not be loading correctly is: nvme nvme0: missing or invalid SUBNQN field, but I don't even know if that's related and googling from there gets people talking in acronyms which I don't understand.

The PC is a refurbished computer from a reputable computer shop, and I replaced (not partitioned) Windows 11 and installed Ubuntu last month. I understand a new one is out this month, but I didn't want to wait. Please tell me what to do.

System:

• Minisforum mini PC
• Ryzen 5 7640HS with Radeon 760M integrated graphics
• 16GB RAM
• 1TB NVMe
• Ubuntu 24.04
• Kernel: 6.17.0-1017-oem

The system crashes at boot without the nomodeset kernel parameter. With nomodeset system is stable but running in low resolution without GPU acceleration.

I've tried:

• Clean install Ubuntu 24.04
• OEM kernel installed
• Multiple amdgpu kernel parameters attempted
• GRUB repaired via chroot
• BIOS iGPU set to UMA_Auto

Persistent secondary issue: Invalid environment block error on every boot.

It's odd that I have to unplug the power cable from the socket to initiate power on. Unplugging the barrel connector at I/O does not allow the power button to function. Do you have any ideas?

I am using Ubuntu Studio 24.04.4.

Is it possible to assign a different IP for each user logging in into my laptop ?!

For instance, when userA logs in, the IP of my laptop would be 192.168.178.10

and when userB logs in, the IP of my laptop would be 192.168.178.20

That would be very handy since I am using the "filter" function of my FritzBox in order to filter websites accessed by my laptop...

I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.

Is there any way to automate the connection process? AFAIK know Apple's computers have some robust connection procedure with iOS devices.

I want to be able to do this for multiple computers with the same phone.

I'm using Ubuntu 24.04.1 LTS and have installed the LaTeX extension for LibreOffice with the tex-live full 2023.20240207-1 package. While the extension appears to be functioning and I can see its icons in LibreOffice, I'm encountering several issues. When attempting to insert a formula using this extension, the formula editor window fits my screen but I can't see the LaTeX icon below the preamble needed to generate the formula. Additionally, resizing the window is not possible. Does anyone know what might be causing this problem?

My sudo apt update output has warnings like the following:

Some of these are my own PPAs (apandada1), and I want to increase their security. How can I do that? Do I have to generate a new GPG key and sign packages with that key?

Recently I have been using Launchpad's recipes to generate PPA packages and don't manually build (and then upload) them anymore. In that case, how to fix this issue of keys using weak algorithm?

The key is not even listed among my PGP keys. It is somehow generated by Launchpad to sign packages generated by Launchpad recipes.

I'm trying to run Ubuntu on VirtualBox (on Windows 11). I followed the instructions here https://ubuntu.com/tutorials/how-to-run-ubuntu-desktop-on-a-virtual-machine-using-virtualbox#1-overview

When I press "Start", I get to this GRUB boot menu screen giving me 4 options instead of the login screen shown in the tutorial. The top 2 options always result in this black screen.

I've seen posts saying what commands to run, but grub doesn't know those commands (e.g. sudo, update-initramfs, apt, get, install; as sudo update-initramfs -u -k version is suggested here)

Additional fixes I've tried: uninstalling and reinstalling VirtualBox, deleting and redownloading Ubuntu 22.04.

What's even more annoying is that I've tried pressing "expert" mode when setting up a new virtual machine, and now every time I press "new" I get stuck in [this][4] screen; there's no next/finish or cancel button.

The only thing I didn't follow in the tutorial is I limited the VM to 10 GB instead of the recommended 25 GB, but now I can't even try 25 GB because expert mode is stuck (even after uninstalling & reinstalling VirtualBox).

I have a web service running using systemd, this service runs by its own user, and I would like to execute some ExecStartPre commands but running as root user. So more in detail:

i.e /lib/systemd/system/webservice.service

After=network-online.target

[Service]

[Install]
WantedBy=multi-user.target

and I would like to have a drop-in service where it fetches from a web-source the config.ini file

i.e /etc/systemd/system/web.service.d/local.conf

[Service]
PermissionsStartOnly=true
RestartSec=5
EnvironmentFile=/etc/environment
ExecStartPre=+/usr/bin/curl http://some.url --output /etc/web/config.ini 
ExecStartPre=+chown web:web /etc/web/config.ini  

The configuration above is not working since my service is freezing during the startup without any message in any log. Is there any way I can make something like that to work?

When i added

stty intr ^X

to my ~/.zshrc file it is always showing stty: 'standard input': Inappropriate ioctl for device on startup.

Please help, thanks in advance.

I'm having issues with an HP elitebook 840 G3. I cannot access information regarding the keyboard back light on Ubuntu 18.04

My keyboard back light works normally (with pressing Fn and F3), that's not the issue, issue is being not able to read back light level from software.

I looked at /sys/class/leds/ and there was nothing that could be keyboard backlight, there were only:

_hp::hddprotect_
_input3::capslock_
_input3::numlock_
_input3::scrolllock_
_phy0-led_ 

Can anyone help me understand where that device might be located so I could read data about it? In order to be sure the keyboard has back light and view/control its brightness level?

I installed Ubuntu 18.10 on my HP EliteBook x360 1030 G3 and can't get all fn-combinations to work.

What works: Volume up/down, Mute, Airplane mode What not works: Brightness up/down, Microphone mute

The often stated kernel parameters as listed here aren't resolving this issue.

Trying the command showkey -k revealed some strange behaviour: For all combinations not working a press and release with the same keycode (465) is generated. The other combinations result in different codes.

When running xev or acpi_listen no event is listed for the malfunctioning combinations.

Would be great if there is a way to get any reaction for this key combinations.

I have made my laptop double boot a few months again, with Ubuntu 18.04.1 . I have been working with okular to open pdf files (for the commenting option) but suddenly okular doesn't work anymore. When trying to open okular I get the following error:

Unable to find the Okular component: Cannot load library /snap/okular/39/usr/lib/x86_64-linux-gnu/qt5/plugins/okularpart.so: (libKF5JSApi.so.5: cannot open shared object file: No such file or directory)

I don't understand how to solve this problem. Okular was working fine until today and I didn't change anything to my ubuntu system in the mean time. Perhaps the problem comes from the fact that I have been working on windows the last few days and also used the windows ubuntu app.

How can I make okular work again?

How do I get rid of the automatically opening search feature on the desktop? I'm not sure what it's actually called. It's the box that pops up (in my lower right corner) when I press a key. It's a search option just for desktop icons, I think.

after installing Ubuntu 14.04 software center downloaded 540MB. when restarted to apply changes it is taking too long. I've waited for more than two hours process is going on like in the image. it is not continuous. There is a break after every line for 30-60 seconds.

Now I cannot update my OS. How much time do I need to stay after restarting? please help me in this regard.

my specifications: 4GB ddr3 RAM. 500GB HDD.

I can use my laptop only in previous versions. Please show me how to have a stable update so that I can use my laptop normally.

I am accessing an Ubuntu 10.04.2 LTS server via SSH from OSX. Recently the colors stopped working. I think it happened while I was installing/troubleshooting RVM, but I am not positive.

In .bashrc I uncommeneted force_color_prompt=yes, and when I run env | grep TERM I get TERM=xterm-color. But still no colors.

Any ideas? Thanks!

Here is the output of cat .bashrc
