Back in the 90s I remember being amazed at the 'dancing postage stamp' videos of the time. I now know that many of these dancing stamps were Cinepak videos. Can I use a modern FFmpeg under Ubuntu to recreate one of these early movies and make it as authentically '90s' as possible?
I made a list on the bash with all the packages installed on Ubuntu.
Trying to restore them to another computer also with Ubuntu, I receive an error message saying that they are not on database.
With this command I made the list:
dpkg --get-selections > list_packages.txt
Then I imported the selection list to the package manager with this command:
sudo dpkg --set-selections < list_packages.txt
Finally, I tried to install the packages with this command:
sudo apt-get dselect-upgrade
There, the message says: packages not in database.
Trying to install them on dissimilar hardware with the same Operating System, I acknowledge the solution.
I had TOR Browser installed and it worked perfectly, until today when it refused to open. I uninstalled then installed it again and got this when I tried to open it:
ldconfig failed, exit status 256
I have received this message with with other software I installed as well. I'm not sure what any of this means. It is taking me time to reacquaint myself with Ubuntu, and I pretty much have to start from scratch each time I load it.
I booted up Ubuntu server to start my home lab, but when I try to connect to WiFi in the first boot thing, it gives me “scan failed: error triggering scan failed -100”. I’m using a TP-link AC600 Nano wireless Archer T2U Nano WiFi adapter.
I attempted to change my dual boot (Windows 11 / Ubuntu 20.04) Lenovo x1 Carbon 8th gen into a Ubuntu 24.04 only environment. After downloading the iso, etc. and choosing a full overwrite, I "successfully" installed Ubuntu 24.04 from a USB drive, but now I can't boot into either Windows 11 (as expected) or any Ubuntu distro.
The boot choices I am given in the boot menu are 4: Ubuntu, Windows, Pxe, and a hard drive. None of the choices boot into anything. All I get is a return to the same 4 useless choices. I want to make the laptop boot into Ubuntu 24.04 only. How can I do that?
I'm trying to change the cursor sensitivity on the login screen, however none of the approaches I could find online seem to work in Ubuntu 26.04. I am using the default setup with Wayland and GDM.
So far, I've tried using dconf as suggested by some article online (sudo -u gdm dbus-run-session dconf write /org/gnome/desktop/peripherals/mouse/speed -0.8), however this fails and returns...
unable to create directory '/var/lib/gdm3/.cache/dconf': Access denied. dconf will not work properly.

Another approach that I could find was using sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.mouse active true, however dbus-launch does not exist in my case.
Can somebody direct me to a method that works on recent versions? I'm quite new to Ubuntu and Linux in general and don't really know my way around. Thank you.
Trying to boot an old computer using a live USB and from qemu I see:
However, the Ventoy thumb drive just hangs. I don't have another system to check the thumb drive on, unfortunately.
Using:
sudo qemu-system-x86_64 -m 2048 -enable-kvm -bios /usr/share/OVMF/OVMF_CODE.fd -drive format=raw,file=/dev/sdb
which seems to work insofar as it shows a boot screen. The boot option does show. However, it just hangs for fifteen plus minutes.

When I launch the Snapshot camera app that I installed via Flatpak, the app opens and shows a frozen image. It doesn't show a real-time image, it shows a frozen image of what the camera sees at the moment it opens.
Device : Lenovo ThinkBook 15 G4 IAP
OS : Ubuntu 24.04.4 LTS
What is the problem? How can I solve the problem? Please help 🙏🏻 Thanks ❤️
I have opened a topic on Snapshot's GitLab page :
I am running Ubuntu on an Acer Predator Helios 16 laptop (dual boot setup with Windows).
When I select "Ubuntu" from the GRUB menu, the system always boots into:
Linux 6.17.0-29-generic
Problem:Wifi, Bluetooth, etc are not working.
However, if I manually go to:
Advanced options for Ubuntu → Ubuntu, with Linux 6.17.0-23-generic
then everything works correctly (WiFi, Bluetooth, etc).
I want Ubuntu to boot 6.17.0-23-generic by default, instead of the latest kernel.
I edited /etc/default/grub:
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
then run
sudo update-grub
sudo grub-set-default "Advanced options for Ubuntu>Ubuntu, with Linux 6.17.0-23-generic"
sudo grub-editenv list
Output confirms:
saved_entry=gnulinux-6.17.0-23-generic-advanced-24bfcac0-c257-44e6-a455-390b94f6815c
However, after reboot the system still boots into:
6.17.0-29-generic
when selecting “Ubuntu” in GRUB.
How can I force GRUB to boot 6.17.0-23-generic by default, instead of always selecting the latest kernel (6.17.0-29-generic) when choosing the main “Ubuntu” entry?
I do NOT want to manually select the kernel every boot
I want a persistent default kernel selection
I am using the instructions on the following site to upgrade from 24.04 to 26.04:
https://help.ubuntu.com/community/QuestingUpgrades/Kubuntu

I was playing in Firefox "forge of empires" when I believe I saw an error note about NVIDIA. I closed all software and did a restart ... to no avail.
@heynnema ls -al /boot screenshot
The computer is booting, all looks fine, but I receive at bootscreen now the error (translated):
forbidden by the secure boot guideline. Loading Linux 6.17.0-23-generic ... Loading initial ramdisk ...
@heynnema this is not easy for me ... I work on your recommendations!
@heynnema nvidia seems to be installed, but there have been error messages, unfortunately in German, which I translated to the best of my capacities:
dpkg: error working at the package nvidia-driver-535 (--configure): dependency problem - it remains not configured
Trigger für libc-bin (2.39-0ubuntu8.7) are worked at ...
errors with: linux-modules-nvidia-535-6.17.0-29-generic
linux-modules-nvidia-535-generic-hwe-24.04
nvidia-driver-535
E: Sub-process /usr/bin/dpkg returned an error code (1)
I don't know how to reboot back to the 29 kernel, because now the "Advanced..." option is missing, when hitting F8 at booting (perhaps because Ubuntu is loading "initial ramdisk"?)
@ maybe here is already something wrong?

I'm using rEFInd as my boot manager and I want to boot Ubuntu 26.04 directly by loading the kernel (vmlinuz), bypassing GRUB entirely and without displaying the GRUB menu. I tried several setup and examples but with no sucess. I don't want to remove grub but just skip it at boot. I need generic rEFInd loader that does not hardcode a kernel version, to always load the latest kernel.

As I'm going through and updating from 25.10 to 26.04, I have noticed that 'software & updates' has been removed. This is something Canonical has advertised ahead of time.
What I want to know is... if any of the functionality (even in part) has been moved to other software? The ability to download and install security patches daily/immediately and the ability to choose which server to download from seems to be pretty vital stuff.
also the ability to alert me when a new version is available is useful too. I know that it is possible to reinstall the app & Canonical may have felt some of the functionality is too dangerous in uneducated hands, but removing all the functionality seems a little harsh. It means that a proper setup will require installing the app from the terminal just to ensure security.
Edit: After running the update on 3 machines, I checked the notes and 'Software & Updates' is not supposed to be removed for updates, it is only supposed to be missing on new installs. Yet it is being removed on updates as well.
Being new to Linux I've installed Kubuntu 26.04. I'm quite happy with it actually, but when I made the first installation, I made the mistake to not encrypt my SSD first. This is not a problem. It's an occasion to learn how to do that, but I've already installed quite a lot of apps and the issue with it is the amount of settings that all those apps require, without mentioning the system itself, security aspects and such.
Even if it will be the same exact SSD on ext4 partition I'm afraid that restoration of the backup may not work as intended because of the encryption and resetting of the partitions.
Then it's not important whether I use a CLI or a UI to do the backup and restoration as long as I have all the necessary directions, but in fact I have no idea if I should use Clonezilla, rsync or Deja Dup. Timeshift only seems to be oriented to file backup rather than the system. What I need is a complete tutorial and for some reason it's very hard to find such a thing although I thought it would be the most common kind of practice. I just get confused with hundreds of contradictory advice on different distros while nobody agrees on any final recommendation.
Help!
I’m completely new to Linux. I’ve dabbled in it over the last 20 or so years but get frustrated and end up back and the dreaded W. So hoping someone can help me with this problem.

Any help would be helpful as I am sensitive to flickering lights.
I’m on Kubuntu 26.04 with KDE Plasma 6 and I’m having issues with color emoji rendering. Some emojis appear monochrome, render just fine

These are my command history I ran before the issue started:

If needed, I can also share the contents of 01-emoji.conf and /etc/fonts/local.conf.
What is the correct way to restore color emoji support on KDE6 / Kubuntu 26.04?

I've been encountering plenty of problems in Kubuntu 26.04 that won't let me use my PC normally:
Translucently and wobble window effects get reapplied after each reboot without my consent.
Chrome on xorg with using the built-in classic option from appearance aka colors, the title bar buttons disappear when I try to type on the address bar.
Plymouth animation appears during transition from sddm to desktop (I have selected None as a transition).
The locale on the time widget in taskbar rejects any effort to be changed and still uses the Greek time format ΠΜ, ΜΜ, When I clearly set it to American am pm. I use Greek only for the keyboard.
I have to note that I also use klassy. I seriously need to find a solution because the name implies LTS and I am disappointed.
I am using plasma 6.6.4. just upgraded.
Since updating to Ubuntu 26.04 on my laptop, I've been having an issue where the screen just goes black after Ubuntu boots up. I see the boot animation, but as soon as I reach the login screen, the screen goes black. When I connect a second monitor, I can see that everything works fine on it. I’ve already found a workaround to reactivate the primary screen: if I briefly close the laptop and then open it again, everything suddenly works as it should. I generated a GPU log of the startup. You can see that after 9 seconds, the graphics card tries to communicate with the screen and apparently fails. A clean install did not fix the problem. Does anyone have any idea how to fix this?

yesterday I updated my Ubuntu 24.04 LTS to 26.04 LTS. After updating, Nautilus file explorer is not displaying thumbnail previews for files added after the update. Is this a bug? How to resolve it? Thanks for the help.
I have HP Envy x360 convertible 15-ds1063cl, AMD Ryzen 5 4500U, Intel NVMe, Micron 8GB RAM. I have/had this very annoying issue with Ubuntu 25.xx 26.04, Fedora 43 & 44 Desktop/workstation. (no dual boot). Every time I power on my laptop, the OS gets stuck on grub or a black screen. I have to remove my USB mouse (Logitech G502 hero or Fantech x17 blake) to boot to the OS.
I tried every solution I could find on the internet, but none of them worked. I tried different USB ports, disabled TPM, Secure Boot, USB boot and virtualization, but I had no luck. My BIOS is up to date. When I remove the mouse and connect any USB device, like an external HD or a USB flash drive, then it works fine without issues, but Ubuntu and Fedora don't like my mice.

May 15, 2026 Upgraded to 26.04 with the same result. No sound and camera
Just upgraded my ubuntu 25.04 to 25.10 hoping that the problem with the sound and camera would be resolved. But sadly it's still the same.
My laptop is a brand new laptop Huawei BoDE-WXX9. However the sound and camera are not working. How to resolve this? Attached the images of the specifics and sound settings. Thanks in advance for any assistance

After a dist upgrade, I get a lot of warnings like this one:
Warning from /etc/apparmor.d/sbin.dhclient (/etc/apparmor.d/sbin.dhclient line 4): apparmor_parser: File '/etc/apparmor.d/sbin.dhclient' missing feature abi, falling back to default policy feature abi
I have an XPS13 with an Ubuntu 18.04.1 LTS running on it. It has a Intel Corporation HD Graphics 5500 integrated graphical card. Everything was fine till the last reboot (before the reboot I have installed some Latex related packages). My display manager now shows only one resolution available:
Additionally, when I plug-in the external display nothing happens. Just before the reboot everything was working perfectly.
The output from xrandr looks as follows:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 3200 x 1800, current 3200 x 1800, maximum 3200 x 1800
default connected primary 3200x1800+0+0 0mm x 0mm
3200x1800 90.00*
and from sudo lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)
Does anyone knows any way to fix that issue?
When I try to run any java program or simply java -version in my ubuntu 14.04 system getting the following error:
"java: error while loading shared libraries: libjli.so cannot open shared object file: no such file or directory"`
I have tried the solution in the this link but it doesn't work
Please help me how to make java work in my system
In tutorials and how-to's I often see commands combined. For instance,
sudo apt-get update && sudo apt-get install pyrenamer
There seem to be four possible connectors: &, &&, || and ;. Though the & connector is clear to me (it sends a process to the background and leaves the terminal available), it is not clear what the difference is between && and ;. And I did not know of || until Kaya's comment.
The following questions deal with the difference between the two connectors, but do so mostly in the comments:
So here are a number of related questions:
; and &&? cd /somewhere_else; rm -Rf * can have destructive consequences if the first element in the command chain fails, for instance.I have a game made with the LÖVE framework and I want to package it into a .deb file so it can be easily installed by others and be easily findable through the Unity dash for example.
I also have the LÖVE framework love_0.7.2.deb which I want to be in the deb file also somehow.
Files that I have:
game_icon.png
game .desktop
the_game.love
love_0.7.2.deb
Could someone explain to me how to do this?
