I got the "Oh no! Something has gone wrong" message after accepting to upgrade to the newest version.

I'm not a developer, just an ordinary laptop and ubuntu user. I haven't had issues so far and don't know how to tackle this.

I read most of the discussions under similar questions here on the forum but I don't understand everything.

I'm starting to think the only solution is to reinstall the OS (I read that even that might not work and I'm starting to panic because I don't want to lose the information on my laptop). If not, I'll be very happy if someone can guide me through another solution process.

I would like to install Ubuntu on my HP PC in dual boot with Windows on two separate disks and put the Ubuntu boot on a separate disk from the Windows one, I wanted to know how safe it was. A thousand thanks!

Xubuntu 24.04 + Ubuntu Studio packages. I'm also using fcitx5 (5.1.7) to switch between en-us and Chinese pinyin input.

Sometimes after a sudo apt-get upgrade, then reboot, the input method icon gets broken. Here, between "notifications" and "Bluetooth," there should be a nice little "us" but instead:

This has happened a few times, and then magically resolves.

Why does this happen? How to prevent it, or fix it if it can't be prevented?

It's a cosmetic problem only -- the functionality is all there -- but... just... no apparent reason why the icon should get trashed.

Thanks.

Welcome to Ubuntu 24.04 LTS (GNU/Linux 6.8.12-9-pve x86_64)

• Documentation: https://help.ubuntu.com
• Management: https://landscape.canonical.com
• Support: https://ubuntu.com/pro

I am a new Linux user, less than 1 month, but trying hard to learn.

I am trying to install "Warpinator" LXC in Proxmox. I have been following the 'Ubuntu 20.04, related' code from https://github.com/linuxmint/warpinator, specifically,

Ubuntu 20.04, related:

• Install build dependencies listed below, note minimum versions:

  sudo apt-get install python3-grpc-tools python3-grpcio
  

• Clone this repo:

  git clone https://github.com/linuxmint/warpinator.git
  

• Enter the folder, specify version:

  cd warpinator
  

• Check out a version you want, or skip this step to build off the current source.

  git checkout 1.2.3
  

• Try to build. If this fails, it's probably due to missing dependencies.

• If you use GitHub Actions to compile, please install the following dependencies.

  sudo apt-get -y install debhelper dh-python meson gobject-introspection cython3
  

• Take note of these packages, install them using apt-get:

  dpkg-buildpackage --no-sign
  

• Once that succeeds, install:

  cd ..
  sudo dpkg -i \*warp\*.deb
  

• If this fails, make note of missing runtime dependencies (check list below), install them, repeat previous command (apt-get install -f may also work).

What I am getting is:

root@Warpinator:\~# ls
warpinator
root@Warpinator:\~# cd ..
root@Warpinator:/# ls

bin                boot  etc   lib                lib32  libx32      media  opt   root  sbin                srv  tmp  var

bin.usr-is-merged  dev   home  lib.usr-is-merged  lib64  lost+found  mnt    proc  run   sbin.usr-is-merged  sys  usr

root@Warpinator:/# cd warpinator

\-bash: cd: warpinator: No such file or directory

I am very new, but how can this be? How can I be in a dir, cd .. out of it, then it doesnt exist? Am I missing some fundamental Linux understanding? or is this some (highly unlikely) Linux error?

I’ve been experimenting with linux more regularly, and have hit a bit of a bump in understanding security. More specifically, Is there a solid way to know if an apt package is safe/trusted? I've heard about the dread Ken Thompson Hack or undetectable rootkits and want to avoid this while still getting the full cutting edge experience.

The question:

• How do packages get maintained and distributed?

• Is it just a wild west of trust like running random github code? Is there a review process like the apple App Store?

• What is the general approach to deciding if a package is safe?

Thanks for the help!

I've lost my password.I tried to login with 4 different password I have used over the years. How many ways can I explain a lost password in order to meet your quality standards. I don't remember my fkn password!!!

I have an AMD-based PC and an RX 570 graphics card. When I boot using Linux live CDs (Ubuntu or Mint), it starts booting and when the graphical part is about to launch, everything goes dark and I can only do poweroff at that point. What can I do to see what is the root of the problem? Windows works fine on this PC.

Safe graphics mode of Ubuntu live CD also works, but it only shows very low resolution graphics.

I am using Ubuntu Desktop 24.04.3 LTS iso image

I have an old computer with 5 hard drives, and Kubuntu 24.04. I am able to connect locally to a shared folder on the main hard drive where Kubuntu is installed, but I get "permission denied" when trying to connect to a share on one of the other physical drives mounted in /media/mrx/Crucial2TB. Here are the configs:

/etc/samba/smb.conf

[ls1]
path = /media/mrx/Crucial2TB/shared
read only = no
browsable = yes
valid users = sambauser, @sambashare
writeable = yes
force user = sambauser

[ls2]
path=/home/sambauser/shared
read only = no
browsable = yes
valid users = sambauser, @sambashare
writeable = yes
force user = sambauser

and the shares:

$ sudo stat /media/mrx/Crucial2TB/shared
  File: /media/mark/Crucial2TB/shared
  Size: 4096            Blocks: 8          IO Block: 4096   directory

Access: (0755/drwxr-xr-x)  Uid: ( 1001/sambauser)   Gid: (  988/sambashare)

and the mount commands:

sudo mount -t cifs //10.0.0.9/ls1 /mnt/local_shared1/ -o username=sambauser
sudo mount -t cifs //10.0.0.9/ls2 /mnt/local_shared2/ -o username=sambauser

the mount point in /etc/fstab for the crucial drive:

UUID=791ec2e1-fb58-4d17-3214-803ee65ff45 /media/mrx/Crucial2TB        ext4    defaults        0 2

I get "permission denied" for ls1, but ls2 works.

I want my browser to be as snappy as possible and I find all the recently introduced AI features to be unnecessary. How to disable all of them?

This question is relevant to Ask Ubuntu because Firefox is Ubuntu's default browser, and optimizing Ubuntu systems for better performance is considered on topic here.

I'm new on ubuntu and my resolution is 1366x768 and scale for big for me. How can i reduce scale %100 to like a %75-80 ?

Thanks for helps and sorry for my English, have a nice day..

I have installed Ubuntu MATE 22.04 and Kubuntu 23.04 on two Chromebooks with amd64 architecture.

The media keys are not working. I can change brightness from system settings, but the media keys are mapped to F1 - F10.

How to make the media keys work? Everything else works perfectly.

Note: The media keys work out of the box in GalliumOS, but it is based on Xubuntu 18.04, and is not being actively developed anymore. I want to use the latest LTS version of Ubuntu in my Chromebook.

I run into a well-known problem that was actually already widely discussed on the web. However, I unfortunately could not solve the problem yet.

I recently replaced the Wifi network adapter into a new one, Intel(R) Wi-Fi 6 AX210 160MHz, in a Dell Rugged 5414 laptop, several years old.

I'm still fairly new to Linux/Ubuntu and appreciate any assistance.

Many thanks to everybody for any support. Please keep in mind, I'm still a beginner with Linux ;)

I made a mistake. I unchecked option for installing 3rd party softwares when installing ubuntu. I followed a instruction that's says to unchecked it when doing dual-boot setup.

I did some research, some say just checked the "software restricted by copyright or legal issues (multiverse)" in software & updates and also do sudo apt-get install ubuntu-restricted-extras. I don't know if this is enough, I haven't yet execute the command. Should I execute this? and there is other things should I do?

My screen goes black after 30 seconds of inactivity and when I press a key, it shows where it was and does not need any password. This problem won't occur when I use it for watching videos in platforms such as youtube etc. My Ubuntu version is 22.04. I have used some methods to overcome it but still couldn't.

1. I've changed screen blank to "never" in setting>power>screenBlank
2. I've used commands such as 'gsettings set org.gnome.settings-daemon.plugins.power idle-dim false', and 'gsettings set org.gnome.desktop.screensaver lock-delay 600' with and without sudo in terminal. I restarted my pc after them just in case. could you please help me with this?

Every time I log in to ubuntu 20.04.4 LTS, my Fn button is toggled to OFF state. So, when I want to change volume, I need to do Fn+Esc and after that I can use my laptop normally. The thing is that the Fn+Esc move which I commit every time after I log in irritates me. Is there any way to make Fn+Esc combination automatically, maybe launching some script? My laptop is Asus.

Are there any AWS S3 browser for ubuntu 20.04?

I saw a lot of options but most of the links are dead or are not maintained .

I'm using Kubuntu 20.04.1 64 bit. To clarify I'm not trying to use this via network but directly via USB cable.

• I cannot receive sound from the micro of my Logitech G432 7.1 Headphone while connected by Audio (In/Out) Jack Socket.

Maybe I could install Logitech software(such as G Hub (?)), to improve the compatibility between Linux and my headphone, but the software are only provided for Windows, or Mac OS, but not for GNU/Linux (Of Course, wine does not want to works with G Hub...)

Is there an alternative on Linux to improve my experience with this headphone ? (Maybe some audio settings could be made with PulseAudio or others as this article may suggest.

I discovered a really nice project (open razer), that could satisfy my needs, but it concerns Razer materials.

NB. This is not really a "vital need", because I can use quite normally this headphone with the USB adapter, but I am still interested. (even if only it is to free a USB port...)

rufus-3.3.exe, the latest version, is not working on my PC. Only rufus-2.18.exe and the versions before it seem to be working. I got this error message as shown at the bottom of the below screenshot:

Failed to download file.

I have downloaded the latest version of Ubuntu 18.10.

I have installed Arduino IDE 1.8.5 I in my Laptop and in UBUNTU 16.04 LTS The option in Tools of PORT is grayed. I want to use Arduino Uno on it but i can't fix it.

As said, I'd like to change default terminal. I've set ctr+alt+t shortcut and it starts xfce4 terminal. But it's bothersome sometimes. There's an option open in terminal/open terminal when u click rmb, but it still opens previous terminal, even though I've set xfce4 as default using this:

sudo update-alternatives --config x-terminal-emulator

Does anyone know how to change it?

I get the error "The system returned: (110) Connection timed out" from the browser when I try to browse through the squid proxy server....Any suggested solutions???

I'm new to Ubuntu and trying to get the application FightCade (fightcade.com) up and running. I followed the directions in the readme file, but have run up against a wall:

I used the terminal to download wine and all the other things, and the readme suggests I should just be able to type ./fightcade to run the application. But I just get the message No such file or directory.

How should I proceed?

am trying to connect to a remote machine (Windows 7 OS) using Remote Desktop Viewer.

I've read carefully This post but still have problems to connect to one of my Bluetooth headset.

I have two bluetooth headsets (SHB71150 from philips, and WeSC Piston along with two bluetooth dongles one from Thrust (bluetooth V3 version) and and Belkin one (bluetooth V4 version).

For both dongles and both headsets Philips SHB7150 and WeSC Piston BT Black I get the same result :

The dongle manages to connect to the headset, but I have no further option in the Volume control to uses the Bluetooth device.

PS : Now things are a bit different : When I try to pair (Either the SHB71150 from philips, and WeSC Piston) the little bluetooth button shows that the pairing is being done but a few seconds later, the pairing is lost.

I've read all the posts related to bluetooth and head sets bu did not find a viable solution.

Could any one give me a hand on this new problem?

I want to connect my bluetooth keyboard (macintosh) at Startup.

But what should i say, i have to enter a PIN, without a keyboard is connected...

Is there a way to connect my keyboard without to buy a USB-Keyboard?

My mouse won't connect, too - i have to enter a PIN there as well!

EDIT: I have a Thinkpad x60s, too. Is there any chance to pair my thinkpad (ubuntu) with my machine (ubuntu) via bluetooth?

I want to create links to software within Software Center using the APTURL - However, I'm not sure how to find out the true "package name". What is the easiest way to discover a package's name for use with the APTURL or apt-get command?
