How to move Ubuntu 24.04, currently standalone, to replace Ubuntu 20.04 on a dual-boot drive https://askubuntu.com/questions/1559556/how-to-move-ubuntu-24-04-currently-standalone-to-replace-ubuntu-20-04-on-a-dua

Currently, this PC has Ubuntu 20.04 LTS in the 256 GB ext4 partition, as shown below, dual booting with Windows 10. This works well, using GRUB to select OS when booting.

Internal SSD

In the meanwhile, I've set up Ubuntu 24.04 LTS on an external SSD, using 140 GB, as shown below.

External SSD

The OS and software on the external SSD is up-to-date, customized to my preferences, and works well.

Though I can switch OS by plugging in the USB drive and changing boot order from the PC's firmware menu, my goal is to replace Ubuntu 20.04 with 24.04, still dual booting with Windows (kept for a few legacy apps, such as current and future tax software). Though I could delete the 256 GB ext4 partition of the internal, making the end of the drive unallocated, and then copy to it the 140 GB Ubuntu 24.04 ext4 partition of the external drive, I'm concerned if GRUB will find either Windows or Ubuntu partitions.

Would simply copying over the 24.04 ext4 partition work, or is there a better way to do this?

For various reasons, I'd prefer not upgrading to 22.04 and then 24.04, among them being that the OS and software on the external drive works as-is, and I have cloned it successfully to two other machines that boot Ubuntu alone.

Sandisk Mini USB Disconnects when Laptop Suspends on Battery https://askubuntu.com/questions/1559554/sandisk-mini-usb-disconnects-when-laptop-suspends-on-battery

I have a 128Gb Sandisk mini USB device that I am using for extra storage on an old Lenovo V145-15AST (model 81MT) running Xubuntu 24.04.2.

I have it mounted using fstab and everything works as intended.

# mount Sandisk 128Gb USB
/dev/disk/by-uuid/3936-3889 /media/Sandisk    auto  x-gvfs-name=USB-Sandisk,x-gvfs-show,uid=1000,gid=1000   0 1

Initially, the presence of the USB drive would cause the system to hang when waking from suspend, but only when running on battery power. The following command

echo "XHC0" | sudo tee /proc/acpi/wakeup

fixed the problem, so that is now automated on startup.

Then I noticed that the USB device would just "disappear" if I left it suspended on battery for longer than an hour. I assume that is to do with power states and entering a deeper suspend/freeze. So I tried disabling auto-suspend by editing GRUB.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"

And checking

cat /sys/module/usbcore/parameters/autosuspend

gives -1 on a reboot.

lsusb gives the following:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 0438:7900 Advanced Micro Devices, Inc. Root Hub
Bus 002 Device 003: ID 0bda:c024 Realtek Semiconductor Corp. Bluetooth Radio

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 0781:5583 SanDisk Corp. Ultra Fit

So I added the below rule to /etc/udev/rules.d/92-usb-input-no-powersave.rules

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="0781", ATTR{idProduct}=="5583", TEST=="power/control", ATTR{power/control}="on"

I also tried with SUBSYSTEMS=="usb", but the USB device is still powered off after an hour. (again, this only happens on battery power).

udevadm info -a /dev/sda

outputs the below:

I notice from some manual experimenting with unmounting/remounting and unbinding/rebinding that the sda block is simply gone, and after a replug the drive is reconfigured under sdc (sdb is the main internal drive). Issuing the below on a normal working system:

echo 0000:00:10.0 > /sys/bus/pci/drivers/xhci_hcd/unbind

then suspending the system for a while before waking then issuing

echo 0000:00:10.0 > /sys/bus/pci/drivers/xhci_hcd/bind

works fine IF the system wake happens before an hour elapses (I think it was an hour but I could be wrong on the exact time it takes to enter a deeper suspend state). At any rate, if I leave it suspended for too long on battery the block device disappears.

This isn't a huge deal since I don't often suspend on battery for any great length of time, and a replug of the USB device is all that is necessary. However, it does happen occasionally and I would prefer to minimise physical replugging if there is another way.

Any ideas? I suspect it might not be possible with that USB device and the 'proper' solution is a bigger SSD. Still, I am open to suggestions.

TIA

EDIT I have added the fstab entry above and will attach dmesg logs of a clean suspend/resume on power versus a failed suspend/resume on battery. I am also going to change the drive from fat to ext4 and retest, although I can't see that making any difference.

System Configuration

Computer Model: Laptop

CPU: İntel I7 14650HX

GPU: NVIDIA 5060 (Laptop GPU)

OS: Ubuntu 22.04.5 LTS

Setup Type: Dual-Boot with Windows

Kernel Version: 6.8.0-87-generic

NVIDIA Driver Version: 580.95.05 (But I tried other versions too.)

Related Software (if any): ROS 2 Humble Desktop, ArduPilot 4.5(But I tried 4.6+ versions), Gazebo Harmonic

I want to develop software for a drone. Following tutorials, I installed ROS2, ArduPilot SITL, Gazebo Harmonic, Python, and MAVROS. When I reached the end and ran the command “ros2 launch ardupilot_gz_bringup iris_runway.launch.py,” I got the black screen error shown in the image. I tried all the solutions generated by AI. I installed the Nvidia graphics card correctly. I tried different versions. I even reinstalled Linux from scratch. I'm sure Secure Boot is disabled. I've tried so many solutions. I also tried different versions of Gazebo. I think it's an issue related to my laptop being new. I tried too many solutions and the error messages got too confusing, so I'm not including the error code. enter image description here

I can't get ubuntu to start https://askubuntu.com/questions/1559547/i-cant-get-ubuntu-to-start

The problem is I don't have a USB with Linux or Windows on . Idk how to fix it without . I tried everything

CUPS not finding existing files; 404 in web interface and server-error-internal-error https://askubuntu.com/questions/1559545/cups-not-finding-existing-files-404-in-web-interface-and-server-error-internal

I purged and reinstalled CUPS because it seemed that several files were messed up and the USB printer didn't work.

Now its even worse; it doesn't even find the printer any more.

When I open the web interface, I get 404 for all pages except home.

Checking the logs, I see a bunch of complaints about "missing files".

Unable to fork /usr/lib/cups/daemon/cups-driverd - No such file or directory.

Unable to fork /usr/lib/cups/cgi-bin/help.cgi - No such file or directory.

I can verify that these files exist:

$ ls -l /usr/lib/cups/cgi-bin/help.cgi 
-rwxr-xr-x 1 root root 48000 sept.  5 17:58 /usr/lib/cups/cgi-bin/help.cgi

$ ls -l /usr/lib/cups/daemon/cups-driverd
-rwxr-xr-x 1 root root 133968 sept.  5 17:58 /usr/lib/cups/daemon/cups-driverd

It might be related to a similar error in lpinfo:

lpinfo: L’exécution de « cups-driverd » a échoué.

Is there an error with permissions? CUPS is running as root.

There are additional errors I get from the log, I cannot find anything on Google about them:

Adding Flutter sdK to the PATH https://askubuntu.com/questions/1559540/adding-flutter-sdk-to-the-path

I am following the instructions at https://docs.flutter.dev/install/manual so that I can install Flutter SDK on my Ubuntu 20.04.6 LTS, After downloading the "linux/flutter_linux_3.35.7-stable.tar.xz" file I extracted it using the command "tar -xf ~/Downloads/flutter_linux_3.35.7-stable.tar.xz -C ~/develop/".

Everything works well.

My challenge is trying to add the Flutter SDK to the path, After running the following command "echo 'export PATH="$HOME/develop/flutter/bin:$PATH"' >> ~/.bash_profile", I am expecting that I should be able to issue the "flutter" command from anywhere in a terminal. It does not work as I always get the '"Command 'flutter' not found' error.

When I look at my "~/.bash_profile" file it says "export PATH="$HOME/develop/flutter/bin:$PATH" which is what I expected.

Why then am I getting the "Command 'flutter' not found' error? I have tried running this from a new terminal and have also tried logging out and in and even rebooting the machine.

Kubuntu 24.04 keeps notifying me about an upgrade it seems like it can't do yet https://askubuntu.com/questions/1559537/kubuntu-24-04-keeps-notifying-me-about-an-upgrade-it-seems-like-it-cant-do-yet

Screenshot of issue, showing that the console wont't allow the updgrade but also showing the notification that an upgrade is available

Only just installed 24.04 a few weeks ago. As you can see in the screenshot, I keep getting pestered to upgrade - with a countdown timer - but apparently actually cannot because some upgrades are deferred due to a phased upgrade plan of some sort. What do I do with this information? How do I get it to either upgrade already or stop notifying me until it can actually do it successfully?

Audio problem with Arrow Lake laptop https://askubuntu.com/questions/1559488/audio-problem-with-arrow-lake-laptop

I have a Lenovo Yoga Pro 7i Aura laptop with Core Ultra 7 255h.

I tried to install ubuntu on it (both 24.04 and 25.10). But the audio doesn't work. I tried any solution I could find: adding options to grub config, adding options to ALSA config, messing with ALSA mixer and pavucontrol, installing linux-generic-hwe, etc. I tried both live sessions and installations of both Ubuntu and Fedora. No matter what I do I cannot get the Intel Audio interface to work. How do I get it to work? Is it even supposed to work?

When I use lspci, I can see the Intel audio interface, but in alsamixer, I only see Realtek. And it is barely audible. The main set of speakers do not make any sound at all.
(The maximum sound I can get out of the Realtek is very low volume and just barely audible. It is as if Realtek is connected to couple of very tiny speakers, and it sounds similar to the phone-call speaker on a mobile phone. )

The 3.5mm jack seems to work fine, but I need to manually switch to headphopnes. It doesn't switch automatically when plugged in.
I don't know how the audio signals are routed internally: if they are routed from a dedicated dsp or from HDMI output of the display driver, etc.

I am not a "pro" linux user, but due to my work I use it daily and I can deal with most problems I face in it. But this one is something I have not been able to solve. Thanks in advance for your help.

Alsamixer only shows the Realtek sound card:

If one of my monitors is bigger than the other, how can I stop my mouse getting stuck on corners? https://askubuntu.com/questions/1559220/if-one-of-my-monitors-is-bigger-than-the-other-how-can-i-stop-my-mouse-getting

I run Xubuntu 24.04.3 LTS x86_64. The Xfce version is Xfce 4.18. I have multiple monitors, but one is much bigger than the other. I am always able to move my mouse from the small monitor to the big one. However, as the screenshot below suggests, I can never move my mouse from the bottom left side of the big monitor to the little one. The mouse hits a "wall" and will move up rather than left until it is over the wall and able to move to the smaller monitor.

display settings

How can I knock down this wall? If one of my monitors is bigger than the other, how can I stop my mouse getting stuck on corners?

For comparison, I'm pretty sure that Windows would let me increase the size of both screens in this GUI and handle the borders intelligently.

I have seen answers mentioning edge resistance. As far as I can tell, none of those settings do anything at all. I have also not seen any Xfce settings related to sticky corners.

Help requested with X11 crash https://askubuntu.com/questions/1558917/help-requested-with-x11-crash

I have been running for a while on Kubuntu 24.04, using Plasma 5 as my desktop. I recently updated to Plasma 6 and have run into a problem that is causing data loss every few days.

The symptom is that the UI becomes non-responsive. The system is still running. I can see updates to some task bar widgets. I can also move the mouse. But any clicks or key presses are ignored, with one exception that I can find. Pressing ctrl-alt-del does bring up the page to sleep, log out, etc., but that page is non responsive, and I cannot navigate away from it. I first encountered the problem with Plasma 6.4.5. I have upgraded to 6.5.0, and am still seeing the problem.

This happens randomly, on average about once every few days. Once it happens, the only recourse that I have found is to reboot the machine. I then lose any unsaved work on this machine, and several virtual machines that it hosts.

When I said that it happens randomly, it's not truly random. It always happens when I click on a UI element. So I reached out to the KDE folks to ask for help with Plasma 6. They helped to narrow the problem down to a crash in the X11 server. Note that I cannot use Wayland as a workaround, as I have a critical X11 app that does not function properly with XWayland.

I checked the Xorg log file and noted the following version and support information:

xorg-server 2:21.1.12-1ubuntu1.4 (For technical support please see http://www.ubuntu.com/support)

I went to the recommended URL, and it appears that the only support offered there is paid commercial support.

Any suggestions on where to go from here? The above information is a summary of the issue. I have more information available, once I can figure out how to reach the right folks to look at it.

For reference, here is the information about the system:

Operating System: Kubuntu 24.04

Qt Version: 6.9.2

Secureboot on HP Z Book https://askubuntu.com/questions/1537782/secureboot-on-hp-z-book

I just got a HP Z Book and I am trying to install Ubuntu Cinnamon 24.0.4.1 on to the laptop. I used Balena Etcher to "burn" the iso onto a USB key. When I try booting off of it I get a message of "Selected boot image did not authenticate". From what I understand Ubuntu should be authenticated and allowed. Is there something I am doing wrong? Is there a different way to put the ISO onto the USB? I can disable Secure Boot but I would rather not.

TIA.

I just to put out this question to see if anybody else is having this problem, and if anyone has tips or pointers on how to debug; I've found one other Manjaro Linux forum post about it, but no solution.

I have Ubuntu 23.10; Thinkpad X1 Carbon 3rd; Canon Pixma870; CUPS+Gutenprint v5.3.4.

This system was printing just fine last week, but this week any attempt to print a pdf from the default document viewer ends with (in the printer status) the error message in the title. I have rebooted computer and printer multiple times. Printing text from LibreOffice writer works fine.

How to configure one-finger touchpad scroll if some hotkey is pressed? https://askubuntu.com/questions/1504061/how-to-configure-one-finger-touchpad-scroll-if-some-hotkey-is-pressed

I often use thumbs to control cursor via touchpad while doing 10-finger touch typing. On Windows and macOS I can configure one finger scroll: if some hotkey is pressed I move thumb over the touchpad to scroll up, down, left and right. This is handy since I don't need to move my entire hand in order for 2-finger scroll.

Is it possible to somehow configure the same behaviour with the latest Ubuntu desktop? I know about the "1-finger edge scrolling" but I want 1-finger scroll for the entire touchpad while hotkey is pressed, since touchpad edges are hard to reach without removing my hand(s) from the 10-finger touch typing position.

Ubuntu 22.04.2 LTS Will not connect to wired internet after update [duplicate] https://askubuntu.com/questions/1461936/ubuntu-22-04-2-lts-will-not-connect-to-wired-internet-after-update

Ubuntu 22.04.2 LTS I can connect to my router, but internet does not work after the last update.

Ping 8.8.8.8 gives me (8.8.8.8) 56(84 bytes of data.

I try ifconfig but says I do not have net-tools installed. I can not download anything as I do not have internet.

I have also rebooted several times. tried unplugging ethernet, plugging back in (obviously works though as it connects to my router via ethernet and my other computer is connect via the same line in from a split box)

I newer to Ubuntu so I will try to answer your questions as best as possible and edit this question with updated info as I learn.

If someone has suggestions for paid support I am happy with that too.

Thank you!

How to debug: Failed to connect to bus: No such file or directory (systemctl --user status)? https://askubuntu.com/questions/1458082/how-to-debug-failed-to-connect-to-bus-no-such-file-or-directory-systemctl-u

I am trying to run systemctl --user status from a user account in order to not run services from root.

The way I do it is as follows:

  1. loginctl enable-linger $USER
  2. export XDG_RUNTIME_DIR="/run/user/$UID"

Then when I run systemctl --user status I get the following error: Failed to connect to bus: No such file or directory

What I tried to debug this.

  1. Setting the DBUS_SESSION_BUS_ADDRESS env variable by: export DBUS_SESSION_BUS_ADDRESS="unix:path=${XDG_RUNTIME_DIR}/bus" This did not fix it. (source)
  2. Rebooting the server after every change.
  3. Reinstalling dbus by sudo apt reinstall dbus-user-session

I also noticed that the XDG_RUNTIME_DIR directory does not exist e.g. sudo ls -l /run/user/1001

I am not sure what else to try or how to learn more about this problem in order for me to able to address it in a more informed manner.

Any info that can help me debug and understand this is very welcome.

P.S. I am running Ubuntu 20.04.5 and the problem likely happened after a sudo apt-get upgrade I ran. Before that it was working well.

Proper way to watch HEVC on supported browser like Chromium https://askubuntu.com/questions/1429206/proper-way-to-watch-hevc-on-supported-browser-like-chromium

I'm currently experiencing issues with HEVC playback on Jellyfin mediaplayer. I've tried almost everything to get it working but it doesn't seem to find the appropiate codecs or something.

My rig has a Intel(R) Core(TM) i3-8109U CPU @ 3.00GHz, which is powerfull enough to watch 4k on VLC, but doesn't work on the browser. Jellyfin starts to transcode like crazy to x264, which causes allot of stuttering and cpu power on my NAS.

What can i do to get it working? I like to watch my 4k content on my browser. Jellyfin client also stutters.

Best regards

20.04 Xbox One controller not working via Bluetooth? https://askubuntu.com/questions/1394906/20-04-xbox-one-controller-not-working-via-bluetooth

I'm trying to connect an Xbox One controller to my Ubuntu machine. What happens when I try to pair it over Bluetooth this:

  1. I open the Bluetooth devices panel in Ubuntu
  2. I hold the button on top of the controller until the light starts flashing rapidly
  3. I pair with the controller in Ubuntu

The problem is, even though it shows as connected in Ubuntu, the light on the controller doesn't stop flashing and it's not recognized in HTML5 games.

Can anyone advise?

Edit: I'm on Ubuntu 20.04.3 LTS

How to install this kernel module to use IpTables in Ubuntu 19.04? https://askubuntu.com/questions/1183231/how-to-install-this-kernel-module-to-use-iptables-in-ubuntu-19-04

So, I am studying IpTables using Ubuntu 19.04 - kernel 5.0.0-32-generic. Following this tutorial https://www.youtube.com/watch?v=ldB8kDEtTZA, I have to load the following kernel modules:

x_tables, ip_tables, iptable_filter, xt_tcpudp, nf_conntrack, xt_state, nf_conntrack_ipv4

The only one not loaded, because it wasn't found in /lib/modules/$(uname -r)/ was the nf_conntrack_ipv4.

My questions are: How do I install/load this module? Do kernel modules become obsolete in new kernels?

Intel HD 520 graphics flickering screen https://askubuntu.com/questions/1146236/intel-hd-520-graphics-flickering-screen

I recently made the switch from Windows 10 too Ubuntu Mate (v18.04) and really like it. However, I just can't get rid of a screen flickering problem. It happens about 50% of the time and affects the left hand side of the screen. The problem didn't exist on Windows. I also tried Ubuntu Desktop (v18.04), and had the exact same screen flickering problem there too.

I've searched google extensively and found lots of people experiencing the same problem. However, no one ever seems to provide a definitive answer to this problem. A common solution proposed is to create a file called 20-intel.conf at  /usr/share/X11/xorg.conf.d/

I have tried this with a few different contents such as:

Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" Option "TearFree" "true" Option "DRI" "3" EndSection

However, none of the proposed solutions work for me and hasn't worked for many others. Here is a list of examples where this same issue seems to be happening:

rtl8822be on 18.04.1 (New Install on Lenovo Legion y530) https://askubuntu.com/questions/1105025/rtl8822be-on-18-04-1-new-install-on-lenovo-legion-y530

Same problem with Realtek Device b822 as discussed in rtl8723ae unstable on Ubuntu 14.04 and New install - no network devices available - Realtek Device b822. Tried installing rtl8822be with and without dkms. None of them works. Here are the details: https://paste.ubuntu.com/p/XkJjD6YmHZ/.

Sometimes, it says "No Wi-Fi Adapter Found". Sometimes, it is "No visible networks".

Updates

I did this:

wget https://github.com/lwfinger/rtlwifi_new/archive/extended.zip
unzip extended.zip
cd rtlwifi_new-extended
make
sudo make install
sudo modprobe rtl8822be

Got stuck in sudo modprobe rtl8822be. It gives me modprobe: ERROR: could not insert 'rtl8822be': Exec format error. Also, this my dmesg | grep rtl8822be output:

How can I run Warcraft 3 on Ubuntu 18.04? https://askubuntu.com/questions/1085024/how-can-i-run-warcraft-3-on-ubuntu-18-04

The guide here : How to install World of Warcraft? has not worked for a decade. this question needs to be answered anew and with the particular context of ubuntu 18.04.1 and Wine development halting:

Wine is undergoing a bit of an odd transition. The maintainers of Wine's staging branch recently abandoned it, but the Lutris project quickly picked it back up.

At the time you're reading this, it might not be a concern, but right now, it definitely is. As a result, the main guide will focus on the latest vanilla Wine release from Ubuntu, but you can absolutely install the latest staging or Gallium Nine versions when they become available.

I think this particular build of Ubuntu is incompatible with past solutions for running Warcraft 3.

I get this screen:

frozen throne fails to install: "having trouble launching battle.net agent"

I've tried many different methods:

  1. All three of the Lutris installers
  2. Play on Linux
  3. This guide which is specifically for 18.04, with wine-staging, but using this source:

    sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
    

    and this WineHQ post

But at the end of the first guide I run:

wine64 ~/Downloads/Warcraft-III-Setup.exe

this sticks out:

0103:fixme:wininet:InternetSetOptionW Option 77 STUB

and I get the screen again:

How to configure iBall airway 3G usb modem in Ubuntu 14.04 https://askubuntu.com/questions/530034/how-to-configure-iball-airway-3g-usb-modem-in-ubuntu-14-04

I bought new iball Airway 21MP 3G modem last month. But Ubuntu 14.04 doesn't detect my device. It is perfectly working in windows with installed driver. I'm not getting an option to "Enable mobile broadband" in top panel. but lsusb list the device

root@eldho-Latitude-E6410:~# lsusb
Bus 002 Device 005: ID 1782:0003 Spreadtrum Communications Inc. -------->>>>
root@eldho-Latitude-E6410:~#

As per the link " How do I get an iball 3.5G modem working on Ubuntu?"
I captured the USB sniffs to find the switch event for a working product ID and vendor ID.
But it shows the same ID in that too.

Please help....!!!!

How to remove all "rc" - residual packages using command line at once? https://askubuntu.com/questions/365965/how-to-remove-all-rc-residual-packages-using-command-line-at-once

I have an Asus Q500A with win8 and Ubuntu 12.04 64 bit; Linux kernel 3.8.0-32-generic. I have been having residual package issues which have been giving me trouble trying to reconfigure xserver-xorg-lts-raring. I tried removing all residual packages from synaptic but the following were not removed. I've been using sudo apt-get purge name to remove packages one at a time, I am down to libieee1284-3:i386 but it is too time consuming. Is there a way I can remove all of them at once, or groups of them?
