I mistakenly clicked install audio packages in Ubuntu Studio Installer, and even after cancelling, my apps menu is cluttered with a whole lot of junk apps.
Where can I find the full audio package list to delete them all please?
I typed sudo apt update to update all my programs on my computer and I get this error:
E: The repository 'https://ppa.launchpadcontent.net/nilarimogard/webupd8/ubuntu jammy Release' does not have a Release file.
How do I fix it please?
I flashed the Kubuntu 22.04 ISO image on to a USB disk and booted my computer. The Kubuntu wallpaper is shown on all screens but nothing else (I assume it's the Kubuntu wallpaper, it looks like a big Firefox logo).
What I have tried
- pushing the Windows key, nothing happened
- Pressing
Alt-TabAndCtrl-Alt-Del, which does absolutely nothing. - Pressing Alt-f1 or f2 brings up the search bar at the top of the screen. I then typed
install kubuntubut nothing starts when I click it.
Can someone please help me?
In Ubuntu settings - default applications. All images are assigned to one application.
Is there a way to assign only .svg to Inkscape please?
I'd like to install Ubuntu to my little SSD disk, and some core applications like Firefox, Inkscape, and Office, but install all other applications with apt to my big hard disk and my home folder (stuff like games, virtual instruments, documents, Haskell/Dart/Rust/npm frameoworks).
How can I do this easily please at install time, or later?
All the answers on here just seem to be people judgmentally saying "you don't need to do that" from a time before SSDs existed I think.
Surely there's a good way in 2022 to accomplish this common task in Ubuntu.
In KDE and Windows I can right click a program icon in the taskbar (like Inkscape for instance) and it will pop up all recently edited files. When I click one it will open in the app.
How can I enable this in Gnome please?
I installed Kubuntu 22.04 on my old laptop and am happy with it. So I installed Kubuntu to my main desktop computer's second hard disk to use full-time as my OS. I then selected that disk as my first boot option in my motherboard settings, and restarted my computer.
Kubuntu shows this message:
[ 0.269691] tpm_crb MSFT0101:00: [Firmware Bug]: ACPI region does not cover the entire command/response buffer. [mem 0xda56d000-0xda56dfff flags 0x200] vs da 56d000 4000
[ 0.269704] tpm_crb MSFT0101:00: can't request region for resource [mem 0xda5 6d000-0xda56dfff]
_
Then asks me to decrypt my drive, flashing the Kubuntu logo, then after successful decryption returns to the error message and nothing further happens. I gave up after 10 minutes and rebooted into Windows.
I also tried installing it to a USB drive, and get the same error when trying to start.
What is going wrong please? How do I fix this?
When I go to IPV4 settings for my wifi and change the DNS IP to Google and click apply, it doesn't change.
The DNS remains the old value in the details tab.
Running docker build . against the following dockerfile
FROM ubuntu:16.04
MAINTAINER [email protected]
RUN apt-get clean \
&& rm -rf /var/lib/apt/lists/* \
&& apt-get update -y
I get the error
E: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/source/by-hash/SHA256/50ccff6c903e98e2e52c1ab6dae4a85d23a84369325fd971c4bfc3752e6a7ede Hash Sum mismatch

I then tried adding every solution in this question to my dockerfile: Trouble downloading packages list due to a "Hash sum mismatch" error

but I get the same error.
What else can I do?
If I open Atom twice to edit different folders there is still only one icon in the taskbar, not two.
Switching between them constantly by having to click, wait for a preview to display, work out which is which, click it, have the screen refresh and animate is incredibly tedious and annoying.
How do I make each instance of the app have its own icon?
Is there a plugin that will do it for me?
My Ubuntu software thingy asked me to update, then presented me with this intimidating choice. Which one is correct? Why is it asking me this?
Whenever I push 'printscreen' or use the screenshot app I capture only my desktop background, see image:
Update
I tried shutter as per Andrea's advice. But it does the same thing, only returns the desktop. However, it outputs some lines on the console that may mean something to someone:
org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.compiz was not provided by any .service files
GLib-CRITICAL **: Source ID 1083 was not found when attempting to remove it at /usr/bin/shutter line 7249.

My Ubuntu VirtualBox VM upgraded itself two days ago to 14.10.
Now whenever I reboot the text on the enter the passphrase screen is clipped on the edges and I cannot type at all in the textbox (using the mouse, or tab, or enter, or any key).
However, if I manually reboot the machine a second time from VirtualBox the screen displays 'Fast TSC calibration failed' briefly and then the passphrase screen displays correctly and I can type. Always twice to get it to work.
What should do I do to fix this? It was working fine before the upgrade.
(I've tried running all the commands in this answer already: (Statement) "Ubuntu 14.10 won't work because black screen" solution described here)
