Whilst trying to find an upgrade path from 22.04 (using gnome session flashback/compiz/lightdm) I installed a fresh 26.04 from USB onto a machine with an i7-3770 and a disc of around 250Gb. Having removed the installation medium and allowed restart I find I am in the grub rescue shell. What can I do with this?
The command apt moo moo used to generate a static output.
But in Ubuntu 26.04 it generates an animated output with an asterix flashing near the cow's tail.

..."Have you mooed today?"...
How does the flashing asterix work? How can I make something similar in my own command line programs in Ubuntu?
First I was using Linux Mint. Now all of a sudden I get a black screen (with no cursor) on boot up. I found out if i go to recovery mode and select Resume I can use the PC, but my PC isn't as powerful / lower speeds and can't use godot.
I've spent some time trying to fix it with no luck. I've even resorted to, with hesitation, using AI to help me. "We" ended up coming to a conclusion that something is wrong with lightdm and that it's a "PAM/keyring integration issue". I have no idea what that means, but the AI kept having me run the same commands, and I was getting fed up, so I decided to do a fresh install of Ubuntu, however I got the same problem. I have to use safe graphics mode in the GRUB menu to boot it up. The main issue now is that it doesn't let me change the screen resolution.
As the topic describes, when I close the lid of my laptop, the os or the desktop environment fails to awake the speaker.
I found some solutions and tried some, but they don’t work, maybe because they are too old.
I also tried debugging it a bit. Here are the details:
So I’m wondering if anybody has ideas of how to debug or solve this problem? Is there a command that can do the same thing as hdajackretask does? Is there anybody have the same issue as I do?
My network settings keep reverting to settings that I don't want. This happens both with my old install (25.10 on an external HD) and with a new install (26.04 on the internal HD, installed yesterday). I have set up my network manually, but every time I boot, the radio button is on automatic (DHCP), and I have to go in and change it to manual. It's very annoying!
What's going on here? Why does this keep happening? How can this happen with a brand new install that hasn't even had any apps installed? I don't get it. All I did was install 26.04, then run the Software Updater. That's it.
I installed linux mint cinnamon as a duel boot. All seemed OK, until I got a message about only having 1Gb of storage left. As I have a 1Tb disc I loaded gparted to have look, (in the mean time I tried to load windows10, no windows!) On gparted /dev/sda1 was showing as microsoft reserved patition and sda2 as basic data partition, flagged msftdata and ext4, but as I said there is no windows on my computer just an error message if i try to boot windows. Any idea what I can do?
I have installed Ubuntu, and have added "nomodeset" due to my PC not reacting on the
loading screen while installing Ubuntu. Now I'm stuck with this screen:
What does that mean? And what is the solution to that problem?
I'll try to summerize this the best I can, sorry in advance for any errors english isn't my first language.
I bought a San Disk sd card specifically to download games from steam into it but at some point whenever I tried to download a game or transfer a game's file from my 'home' storage to the sd card, I'd get an error pop-up and couldn't finish the download. So I tried randomly modifying the sd card's partition and file system after a quick only search.(I do realize now how stupid of an idea that was, especially since I didn't look online long enough...)
In the end I think I might've just turned the card useless since I can't modify anything or transfer/download anything into the sd card. When I try to mount the SD card I just get a "can't mount file" message.
These are the details of the SD card in the media and etc manager:
Model: SK128
Size: 128GB(127.999.672.320 bytes)
Partitioning: Unknown (PMBR)
Contents: Unallocated Space
Device: /dev/mmcblk0
I'd be really grateful if anyone could help. I don't care much about retrieving the lost data, I just want the SD card to work again.(I'm on Linux Mint 21.3 MATE64-bit if it matters..)
[UPDATE - Not quite a resolution yet] I managed to get back to a 2560x1440 signal on my monitor!
How? by doing a "power cycle" on my computer AND my monitor, I guess like LetterheadClassic306 mentioned, the DP Handshakes stayed on otherwise.
Two issues remaining though :
Any guess as to why or how to fix it from here?

It was working fine before I tried to connect it through a KVM dock.
This one: https://www.avaccess.com/products/idock-b23/
Then I remove it from my setup.
But since then, my monitor is no longer showing any signal, but is well detected:
My screen showing the displays connected, we can see that both screen are connected
I've tried:
Does anyone have any idea how to fix this problem?
I have a Ubuntu server running in my home. Mostly for streaming movies and such but we just got a laptop for the kids and I was trying to set up samba so I can share files from my windows desktop to the laptop, but I'm running into a snag. When I attempt to connect to the share it asks me for my username and password but then I get a message that windows cannot access this network resource:
when I read log.aragorn (name of my desktop) I get

I am using Ubuntu 24.04.
Currently, with the standard unity-like desktop (because my preferred choice of gnome flashback/compiz/lightdm doesn't currently work properly). If I have multiple instances of the same application, e.g. spreadsheets, I wish to keep them in a specific order in the icon strip on the left hand side. I can do this by creating them in the order I want, but sometimes they seem to get moved on their own.
I want to move them back to my preferred order without having to close and reopen them all. All the answers I've found online suggest that you can drag and drop them, but this doesn't seem to work. Once dragged, wherever I try to drop them, they gain a small "no entry" sign (circle with a diagonal line through it) and simply fall back to where they started.
I'm running Ubuntu 22.04.5 LTS and recently installed FireFox 152 through the apt install channel.
When I open Settings/About Firefox, I see the Firefox updates is set to "Updates are managed by your operating system." There doesn't seem to any longer be a setting to check for updates manually or to notify me that an update is available so that I can chose when to do the update.
I opened about:config and changed app.update.auto from True to False, but that had no effect.
I would like to be able to disable the automatic updates so that I have control over when the updates happen. What are the steps to do this?
Additional info: Prior to today I was using Snap to update Firefox. Something went haywire with the auto update that broke Firefox, so I no longer care to use Snap.
More info: I added a config file to /etc/apt/preferences.d so that firefox should no longer be using snap.
$ apt policy firefox
firefox:
Installed: 152.0.4+build1-0ubuntu0.22.04.1~mt1
Candidate: 152.0.4+build1-0ubuntu0.22.04.1~mt1
Version table:

1001 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 Packages
100 /var/lib/dpkg/status
The only information I'm looking for is: "How can I configure firefox so that it will notify me when updates are available so that I can choose when to apply the updates." It's just that simple. If there are config setting changes to allow that behavior, that will be the perfect solution.
Recently my system (24.04) suggests the update Microsoft’s 2011 UEFI and KEK CAs are set to expire in June 2026 and are being replaced by 2023 CAs. This is also discussed at this link.
Is it safe to update or should I ignore it?

I am trying to install Ubuntu onto an older Dell laptop using a freshly flashed and validated SanDisk USB 3.0 drive (flashed via balenaEtcher).
The boot sequence starts up fine, but it completely freezes every single time right after reading the very last APT cache repository line:
Get:5 file:/cdrom resolute/main amd64 Packages [31.7 kB]
I tried:
Replaced the USB drive entirely (originally used a generic UDisk which threw I/O buffer errors, switched to a brand new SanDisk 16GB).
Removed quiet splash from the GRUB menu to view the verbose terminal logs.
Tried booting with nomodeset (Safe Graphics mode).
Tried appending various combinations of boot flags like acpi=off, noapic, and irqpoll.
The logs:
Right before it hits the Get:5 line and hangs, the logs show a couple of errors regarding the communication bus and filesystem:
fuse: device /dev/fuse not found. Kernel module not loaded?
dbus-daemon: A connection to the bus can't be made
Failed to create stream fd: No such file or directory
This is the terminal output right at the freezing point. Since it is stalling the exact millisecond it finishes loading the configuration files and tries to hand over control to the display manager/graphics, I suspect it's a legacy hardware or kernel conflict with this specific Dell motherboard architecture.

I remember that some years ago there wan an app that enabled you to make persistent USB drive. There was a slider and you were able to set the amount of persistent space on the USB drive.
Now it seems it is not working anymore. I tried mkusb, but it is not working. I am trying to install Ubuntu 20.04.1 persistent image on live USB.
I'v installed open-vm-tools successfully on Ubuntu 20.04 guest in VMWare Workstation 15 on Windows 10 host.
Both full screen and shared folder work fine after the intallation.
But after reboot the VM, both full screen and shared folder don't work anymore.
These are what I'v tried:
sudo apt-get remove open-vm-tools
sudo apt-get install open-vm-tools
in the process of reinstallation, there is some message like:
failed to restart open-vm-tools.service unit vgauth.service is masked
but after some search I tried:
systemctl list-unit-files|grep 'open-vm-tools'
systemctl list-unit-files|grep 'vgauth'
both are "enabled"
then
systemctl stop open-vm-tools
systemctl start open-vm-tools
no messages.
What next?
I see that Ubuntu server after the installation comes as default with NetPlan with a DHCP configuration (at least in Ubuntu 22.04 focal fossa).
Some users don't want NetPlan and just want NetworkManager, for example to use nmcli, nmtui, or import VPN configurations etc. and so after the installation I think it's frequent to migrate to NetworkManager.
At the moment this is my procedure to migrate from NetPlan to NetworkManager after a clean installation.
Create this file:
/etc/netplan/01-er-netplan-fix.yaml
With this content:
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
# Set and change netplan renderer to NetworkManager GUI tool
network:
version: 2
renderer: NetworkManager
Then run these commands:
# install Network Manager
sudo apt install network-manager
# disable NetPlan
mv /etc/netplan/00-installer-config.yaml /etc/netplan/00-installer-config.yaml.bak
# reload NetPlan
netplan apply
# I'm not proud of this but I reboot to apply everything now
reboot
Problem: when I reboot, the server obviously disconnects, but also it never renews its IP via DHCP.
As workaround, I open a physical terminal on the server, I run dhclient, and then I continue with nmtui adding a simple Ethernet configuration with DHCP, and everything is good again.
So my question is: how to migrate from NetPlan to NetworkManager? Possibly automatically renewing its IP? Possibly without any disconnection at all? so your SSH connection is not interrupted.
Feel free to suggest as answer to prefill at least a valid NetworkManager configuration for a valid DHCP after the reboot but I still don't understand if I can also avoid the reboot at all and keep a working SSH connection to do the whole migration process.
Thank you for your thoughts! Maybe this question is stupid but I don't know NetPlan, since I usually use Debian and I don't have these problems.

My internet speed on Ethernet port is hard stuck at ~100 Mbps on wifi I get more than 500 Mbps my internet runs at Gigabit and I have full bandwidth on Pop OS live, windows on the same machine and wire.
The problem is not with the wire and router but with Ubuntu 20.04 and 21.10 for certain.
I am using CAT 7 Cable
I've tried everything and even tried upgrading to 20.10 with no luck what could be the issue here

I am trying to attach a USB device to my Ubuntu 20.04 distribution running under WSL2.
The problem is that when I run the usbip command, it gives the following message:
WARNING: usbipd not found for kernel 5.10.16.3-microsoft
You may need to install the following packages for this specific kernel:
linux-tools-5.10.16.3-microsoft-standard-WSL2
linux-cloud-tools-5.10.16.3-microsoft-standard-WSL2
You may also want to install one of the following packages to keep up to date:
linux-tools-standard-WSL2
linux-cloud-tools-standard-WSL2
I tried doing:
$ sudo apt install linux-tools-5.10.16.3-microsoft-standard-WSL2
... but that doesn't work. It returns the following:
Reading package lists... Done

Reading state information... Done
E: Unable to locate package linux-tools-5.10.16.3-microsoft-standard-WSL2
E: Couldn't find any package by glob 'linux-tools-5.10.16.3-microsoft-standard-WSL2'
I have been Googling how to install them, but I can't find anything about this.
NOTES:
uspip is called by usbipd wsl attach -b 2-2 from PowerShell because I am trying to attach a USB device to Ubuntu5.10.16.3-microsoft-standard-WSL2I know we can view animated SVG files using web browsers. I wonder if there is a software that works exclusively as an image viewer with SVG animations support.
I'd like to get a list of packages installed manually by snap and be able to find out whether a foobar package was installed manually by system installer.
For example:
$ snap list

However, I'm not sure if this is the right way to exclude automatically installed packages. Is there any neat way of doing that from the command line?

If the ASCII character encoding is not UTF-8, there is more than one Driver Manager installed and your application is using the wrong one, or the Driver Manager was not built correctly.
EDIT:
odbcinst lists only one driver:

I've found post suggesting that problem might be caused by python.
Basically I want to be able to right click on one of my folders and use something like 'Thunar Root', type in my admin password and continue to use it. Now I've quite a big trouble getting some files to my admin privileged folders. Also, isn't the default XFCE file manager called Thunar? Why is it called plainly 'File Manager'?
Many thanks.
I have Ubuntu Mate 15.10 on a USB flash drive. I booted into it and looked to connect to my wifi and it was not listed in my networking connections. I looked in network connections in the system menu and it doesn't have any wireless adapters listed. Only the ethernet.
I've run lsusb and my wireless adapter is listed there. I just don't know where to go from here in getting it running. Learning this as I go.
Thanks for any help.

I have Xubuntu 14.04 on a SSD device (the HOME was encrypted correctly during intallation), additionally I have a HDD with a encrypted partition with extra data which I would like to mount in /mnt/hdd. For making these I followed the next steps:
(Previously I had encrypted the disk with LUKS following this post http://www.marclewis.com/2011/04/02/luks-encrypted-disks-under-ubuntu-1010/)
Check the UUID
sudo blkid
/dev/sda1: UUID="b3024cc1-93d1-439f-80ce-1b1ceeafda1e" TYPE="crypto_LUKS"
Make a keyfile with the right passphrase and save it in my HOME (which is also encrypted).
sudo dd if=/dev/urandom of=/home/[USERNAME]/.keyfiles/key_luks bs=1024 count=4
sudo chmod 0400 .keyfiles/key_luks
Add the key
sudo cryptsetup luksAddKey /dev/sda1 /home/zeugor/.keyfiles/key_luks
New entry in /etc/crypttab
hddencrypted UUID=b3024cc1-93d1-439f-80ce-1b1ceeafda1e /home/[USERNAME]/.keyfiles/key_luks luks
Update the initial ramdisk
sudo update-initramfs -u -k all
Then, to test it, I used the follow command to start cryptdisks:
sudo cryptdisks_start hddencrypted
* Starting crypto disk...
* hddencrypted (starting)..
* hddencrypted (started)...
To check hddencrypted was mapped:
ls /dev/mapper/
control hddencrypted
Create a mount point
mkdir /mnt/hdd
New entry in /etc/fstab
/dev/mapper/hddencrypted /mnt/hdd ext4 defaults 0 2
Validate fstab without reboot:
sudo systemctl daemon-reload
sudo mount -a
Mount the encrypted partition on boot
Now I have mount it in/mnt/hdd as I proposed. But I wold like to make this automatically after reboot. But before I can log in, I get this error:
the disk drive for /mnt/hdd is not ready yet or not permit
All this makes me think that /etc/crypttab can't access to the keyfile which is located in my HOME (other encrypted partition). I don't know the order which the system follows to unencrypted and mounts the units. My HOME should be unencrypted before my HDD for giving access to read the keyfile.
I would appreciate any insight as to why this happens.
UPDATE: If I locate the keyfile in /boot (no encrypted), instead of in my /home/[USERNAME] (encrypted) the /dev/sda1 and update the entry in /etc/crypttab is perfectly mounted on boot time.
I'm using Ubuntu in VirtualBox on Mac. As I switch frequently, I would like to use the same shortcuts. Please, does anyone know how to have the same shortcuts on Ubuntu, as they are on Mac?
Specifically, I would like to Copy, Paste, Select All, ... work with Cmd+C, Cmd+V, Cmd+A, ... (even in terminal - no Ctrl+Shift, just Ctrl).
I tried to change Keyboard Layout to Apple Laptop, but that didn't help.
