I installed 3.11 only my OS (22.04) but VideoDownloader still comes up with an error and seems to point or link to 3.10
Anyone know how I change this (or where the videodownloader config is)
Can You Unleash that Package for me, Its Very Important!
1. nvidia graphic driver is not installing properly on ubuntu os.
2. nvidia graphic card is not supporting correctly. without full support of nvidia gpu the os is not complete enough.
I was setting up a backup program for my newly installed Ubuntu 26.04 when I accidentally deleted all the files (and symlinks) which reside in the root folder of my system. No folders were deleted or changed. I don't have a backup because I haven't set that up yet.
How do I restore those files and links so that the system will boot again?
I can run the demonstration mode of the installation USB to just copy or create what is necessary.
My Kubuntu system can't figure out how much free space is left on my hard drive. There are three sources (as shown in the screenshots), and they all provide different information. I'm inclined to believe that I should have around 190-200 GB of free space, but the installer won't let me install files larger than the claimed 160 GB. Where did the other 40 GB go?
From what I gather, the main feature of Windows "Live File System" is not a Windows thing, but actually a feature of UDF revision 1.50 (1997). It added support for the "Virtual Allocation Table" (VAT), which allowed packet writing; that is, you can sort of treat the CD-R/DVD-R, which are WORM (Write Once, Read Many) as a rewriteable filesystem (not disc, filesystem).
Given this apparent generality, I imagine Linux does support this. However, I only found this, but it seems weird, since I found no udftools service nor the file where it says to be present. And I also suspect pktsetup (of Debian package udftools) has something to do with this, although I do not get its language nor explanation.
So! How do I do this?
I've been trying to get my UB600 Bluetooth dongle to work, however it seems that it's not compatible out of the box. In fact, there's only 1 place with a solution how to get it to work however it seems the explanation on how to do it goes over my head. I've tried using what they gave me in konsole but some things just error and I can't seem to get around that. The fix I've been attempting is this. The issue I'm having is, it detects the Bluetooth dongle, but the computer is then unable to detect any Bluetooth devices at all. The lsusb is exactly as shown on that link as is the journalctl.

Is there any chance somebody could explain to me like I'm a 5 year old how to apply that patch, or better yet, create a solution for me? I am running Kubuntu 26.04 on kernel 7.0.0-27-27.
I have recently set up a server on an AWS EC2 instance with Ubuntu 24.04. I am trying to change the configuration to authenticate via password but when I try to log in I get a 'Permission denied, please try again.' error message.
I have done the following:
codename: noble openssh-server: 1:9.6p1-3ubuntu13.16 amd64
I have a Dell Inspirion-16-5625 (Ryzen 5625) laptop and a ADATA Legend 800 SSD. I used it with Xubuntu 22.04 and 24.04 without problems. Now I updated to version 26.04 and I have at almost every cold start a system freeze after some time. Sometimes it switches to the boot screen, sometimes I can change to a console where I see a journald message saying that the file system is read only (trying to write in an endless loop), sometimes just freezes.
After a restart I often have to enter my dmcrypt password twice.
I have also Windows 11 installed which works without errors and after a warm start Xubuntu also works, so I think I can exclude any hardware problems.
I already searched in internet and I found some things:
I tried everything I found in internet, but it seems that now its nearly at every cold start, before some cold starts worked.
So what I did:
For now I have no more idea what I can do. I will attach the dmesg and journal of the last freeze.
I installed Ubuntu 26.04 onto my Dell Precision M4700 laptop. I was seeing some error messages during boot, and some of the googled suggestions were to turn on UEFI in the BIOS of the dell. I turned on Secure UEFI and 26.04 continued to boot, and the error messages went away. However, the problem is that Dell had an issue with the UEFI being buggy with the graphic cards in the Dell M4700, so from that point on, I can't see the bios (or anything) until Linux loads the drivers. The point is, I can no longer interact with the BIOS and have to wait for Linux to load. Well, now I want to reload Ubuntu 26.04 again from bootable USB pen drive, but can't interrupt the bios to do it (or change the boot order in the bios). My question is, since I can fully boot into Linux at this point, is there something I can do with Linux to force it to boot from the USB drive, so that I can reload Ubuntu?
I have an old server, with "mdadm - v3.2.5 - 18th May 2012", on Ubuntu version 12. Before trying to move my 5 disks RAID6 to the new server, I created an image with ddrescue of each disks (3TB per disk).
The new server is Ubuntu 26, with "mdadm - v4.5 - 2025-12-16 - Ubuntu 4.5-5ubuntu1"
On the old server, I can create "loop0-4" devices with losetup. and use the command:
mdadm --create /dev/md123 --assume-clean --level=6 --raid-devices=5 /dev/loop3 /dev/loop2 /dev/loop4 /dev/loop1 /dev/loop0
I can then mount the device and access my data.
I can use mdadm --assemble as well

I get the following message in dmesg for the two removed drives( images)
md: kicking non-fresh loop0 from array!
Those are image files, the files have not been modified by the OS during boot, or anything else.
Why does the newer mdadm does not recognize all the 5 disks/images?
How can I "fresh-up" loop0 and loop4
Again, the same image file works just fine on the old server.
It is peculiar that it removed two disks. Since it is a RAID6, removing two disks is OK. I should be able to recover the data, but it would be risky if ever one disk fails. The five images are spread over 3 disks, two 4TB and one 1 TB drives.
so i've disabled nested virtualization in light of this CVE https://ubuntu.com/security/CVE-2026-53359
Is there a fix? How can I get the fix because I've disabled nested on my proxmox, but I actually kinda need it for my platform.
Thanks <3
Can i install the Nginx 1.30.3 source download from Nginx.org since not seeing the update release for nginx 1.30.3 in the Ubuntu official site. Is it recommended to install the source from Nginx.org in the Production servers?
Not very familiar with Ubuntu, so this may be simple. Basically I want to run an app image from a FAT32 formatted USB stick. Needs to be FAT32 for portability reasons.
The app image is Veracrypt, and I'm trying to make a portable version so I can just plug in the stick and run it. I read that which one can create a 'traveller' version in Windows (done that), in Linux, you need to use the AppImage - which is fully self contained.
So, the stick has on it a file 'test' which is the encrypted volume created in Veracrypt, plus a folder to contain the executable. So, put the AppImage into the folder.
But, try to run it, and I can't, because it doesn't have execute permission - which I cannot set because it is FAT32.
So, created a script veracrypt.sh containing
#! /bin/bash
sudo VeraCrypt-1.26.29-x86_64.AppImage
Same problem, cannot make it executable.
Cannot see how to get around this, suspect it might not be possible from FAT32? I suppose I could co[y the app image to somewhere on whatever system I am sitting it and make it executable there, but it's a clunky answer.
Basically, what I need to do is create a self contained version of Vercrypt on the USB stick, that gives root permissions to the app. The reason for root is that Veracrypt needs it to mount a volume.
I updated Ubuntu 24.04 when the popup window for the software updater showed up and asked if I wanted to install the updates. I chose to 'install' and then did a restart and when I went to YouTube, videos don't play. I get the list of videos, but when I click on a video, it opens the new page and everything comes up, but no video window and no video. On this other computer YouTube is playing videos. Both have Firefox version 152.0.4 and are running Ubuntu 24.04. I also tried getting the URL from the "Share" icon. I copied it and pasted it into the address line but that didn't work either.
With Xubuntu 24.04 the File Manager sees, in "Browse Network", NFS mount points. With Xubuntu 26.04 NFS mount points are not visible but can be reached by specifying the mount point.
I tried to use the comment=x-gvfs-show but this seemed to have no effect. Using gio to mount the NFS mount point gets the error message "volume doesn't implement mount".
Is the "File Manager" in 24.04 a different implementation than the one in 26.04?
I've already checked:
systemd-analyze blamesystemd-analyze critical-chainjournalctl -bI just did a fresh install of Ubuntu Server 26.04LTS, and am seeing loads of broken links already.
Since installing the OS, I have done an apt upgrade, added one additional user, and a static MoTD, so almost nothing really.
Yet, when I run:
sudo find / -xtype l -ls
I get scores (at least) of broken links showing up (I can post a complete list if it would help). If I exclude some paths thus:
find / -xdev -xtype l \
-not -path "/proc/*" \
-not -path "/sys/*" \
-not -path "/run/*" \
-not -path "/dev/*" \
2>/dev/null
it reduces the number of broken links listed to this list, which is still surprising (at least to me!)

Is it expected that there would be a load of broken links on a fresh install? If not, perhaps something went wrong when I installed, and I should wipe and start from scratch, or perhaps the disk is knackered (although I did run the built-in disk diagnostic from the boot menu, and it found no issues).
Any suggestions welcome, and given I have almost nothing invested, I am also happy to use this for any tests that might be useful to understand what is happening.
I just upgraded my Ubuntu 24.04-4 MATE install to the latest version. I noticed that in Firefox the save dialog box refuses to save a file on the proposed location when hitting [Enter] like it always did. I first blamed Firefox but it is system-wide. Any GTK app has this unwanted behavior. Other PCs, a fully up-to-date Linux Mint 22.3 workstation and a fresh test install of Ubuntu 24.04 MATE on an HP USDT (Ultra Small Desktop) save just fine on [Enter].
But not only that, I also noticed files being overwritten without any warning when clicking Save (or using [Alt]+s). Barring a complete system re-install, how can I fix this?
Since a v151 Firefox supports Webserial natively. For me this is an long awaited function. But I cannot seem to find any documentation on how to get this running with the installed snap version in Ubuntu (26.04 in my case).
What I tried:
The serial port I wanted to try is popping up in the /dev folder as 'ttyACM0'
I read about webserial with Chromium (snap) where you need to connect the raw-usb to snap. But raw-usb seems not to be available for firefox
# sudo snap connect firefox:raw-usb
error: snap "firefox" has no plug named "raw-usb"
with:
sudo snap connect chromium:raw-usb
everything works as aspected but I prefer firefox
Is the snap package just not ready (yet) or is there anything else I can try?

I created the iso image using "dd" with command: sudo dd if=ubuntu.iso of=/dev/sda status=progress bs=10M && sync but i don't think that's the issue here cause i installed Ubuntu 24.04 in the exact same way and boot settings and chose the option to erase disk (uninstall windows 11) and it worked.
Edit 1: I am trying to install ubuntu-22.04.4-desktop-amd64.iso and previously i installed ubuntu-24.04-desktop-amd64.iso without any issues with same boot settings.
Edit 2: Based on @oldfred's comment, here's the output of "gdisk" command:

Apart from "dd", i also used "etcher" to flash the ISO again and even reflashed the ISO with "dd" again but cleared the partition table with: sudo wipefs --all /dev/sda this time to see if it works & encountered the same error in both cases. I even changed my USB to another one but that also resulted in same error so i assume it has nothing to do with the USB am using.
I have been using chrome on ubuntu for years without problem. Since a while, it complains it is no longer the last version. I honestly don't remember how it was installed to begin with, most likely snap or apt, but neither indicate they can do any update. Everything is up to date. I don't know, maybe it has something to do with the 24.04 update? To be clear, I updated to 24.04 a while ago.
All I have to go on is this menu button:
I don't know where to start. I don't even know how to check how it was installed. I have tried to google this but I get mostly posts from 9 years old. Can anybody give me a few pointers, how to resolve this? Greatly appreciated!
I have recently set up a server on an AWS EC2 instance with Ubuntu 24.04. I am trying to change the configuration to authenticate via password but when I try to log in I get a 'Permission denied, please try again.' error message.
I have done the following:

I have tested removing cloud-init using this guide on Ubuntu Server 22.04 and Ubuntu Server 22.04 (minimized) installed with the default settings. Uninstalling cloud-init from full Ubuntu Server does not mark important packages for removal, but doing it from the minimized version did so. See the screenshot below. If I execute sudo apt autoremove after that, and restart the server, the Internet is no longer accessible and all Internet-related commands are not found.
Is that a bug? If not, can I remove cloud-init from the minimized version without destroying network access? I am not using cloud. I just wanted a bare-minimum Ubuntu desktop (I add Xfce to this).

Hello I have a dualboot system with Ubuntu 20.04 and Windows 10 and the time of installing Ubuntu 20.04 I disabled fast startup in Windows to get rid of possible errors. But now I want to turn that feature ON because of slow Boot,slow shutdown and restart. So by some finding on Internet , I came to know that turning on that Windows feature ON in dualboot can cause data loss. So I do I enable that feature On without any data loss?
I can read and write Windows drive, did I have to change it to read only? and if so then how can I do that with GUI because terminal commands are confusing and wrong command can mess everything. Thankyou.
I'm trying to enable hibernation on my laptop, and discovered that my problems could have something to do with my Nvidia drivers. So I found this fine document on help.ubuntu.com which tells me to change some settings in /etc/X11/xorg.conf. But it's empty! So what do I do now?
I have three ssd's (ssd0, ssd1, ssd2). ssd0 and ssd1 have Ubuntu 18.04 installed on them via this procedure in the Ubuntu installer:
Erase disk and install Ubuntu
That means I have full disk encryption, LVM and grub2 on ssd0 and ssd1 like this (output from lsbulk):
ssd0:
sdb 8:16 0 447,1G 0 disk
├─sdb1 8:17 0 512M 0 part /boot/efi
├─sdb2 8:18 0 732M 0 part /boot

├─ubuntu--vg-root 253:1 0 445G 0 lvm /
└─ubuntu--vg-swap_1 253:2 0 976M 0 lvm [SWAP]
ssd1:
sdc 8:32 0 447,1G 0 disk
├─sdc1 8:33 0 512M 0 part /boot/efi
├─sdc2 8:34 0 732M 0 part /boot
└─sdc3 8:35 0 445,9G 0 part
└─sda3_crypt 253:0 0 445,9G 0 crypt
├─ubuntu--vg-root 253:1 0 445G 0 lvm /
└─ubuntu--vg-swap_1 253:2 0 976M 0 lvm [SWAP]
ssd2 has win10 installed on it.
Both grub2 bootloader (grub2 on ssd0 and grub2 on ssd1) recognize win10, but both grub2 bootloader do not recogize the other Ubuntu installation.
Why is that and how can I make it work?
The desired configuration would be that I still have a seperate grub2 on ssd0 and ssd1 and both should recognize the other Ubuntu (as well as win10) such that I can remove ssd0 or ssd1 and still have a a bootloader for the Ubuntu/win10 dualboot. When ssd0, ssd1 and ssd2 are connected, then I simply set in the BIOS which bootloader to use, wheter the bootloader from ssd0 or the one on ssd1.
Some probably necessary information:
I have a systemd service which calls a PHP script that creates a tmux session on boot.
Globally I have the most current tmux for the distro (V>=2.5).
The script's USER has a $HOME/bin/tmux of 2.0
What I need is for this systemd to use the tmux binary in the user's $HOME.
I have set the USER & GROUP variables in the systemd service file but it seems to call the globally installed binary.
Is it possible to explicitly set the binary that should be called for this service invocation?
If possible I'd rather not start to hardcode the path in the PHP file itself.
Many thanks.
