How do I install Psiphon on Ubuntu 20.04 LTS (Step by Step)

I am trying to Install Ubuntu server 20.04.4 on a 705 G4 Mini Desktop pc and I cannot because whenever I get to the Guided storage configuration i get the message "Block probing did not discover any disks. Unfortunately this means that installation will not be possible".
I have searched the issue and discovered other posts saying I have to reconfigure the RAID, but when I boot up the BIOS, the settings the posts point me to do not exist, and I have checked every part of the BIOS for any relevant setting and came up empty.
I also found that a mounted file might be causing the error, so I used the given solution which was to boot up the terminal and run:
losetup -d /dev/loop0
umount /isodevice
but that gave me a message saying that there were no mounted files so I think that isnt the problem either.
I have no idea what to do or if these two items are even compatable (research says they should be) and would like any insight into the problem.
Thanks, William
I'm using Ubuntu Studio, now with Ubuntu Pro enabled... I just rebought Native Instruments awhile ago, and Windows isn't affordable since I only get $62 a month or less from SSI in a nursing facility mental health place... I splurged to take money I didn't realize I had onto Native Instruments. I also have full fledge FL Studio. I do not want to get a Virtual Machine to install this software on Windows, as it is no longer a secure option for me. My enemies have already torn it a part, and they even try messing with Ubuntu Studio, to no avail for them. I've been hacked numerous times, but only through my own system, as noted after a 6 month crap situation inside a mental hospital where my phone and laptop weren't running. They could not do any hacking then. I'm just curious on how to run
Native instruments and FL Studio in Ubuntu Studio. If I have to buy something to make it run correctly, or is there a method to WINE or otherwise I'm not familiar with? Because last time I used linux was in 2009 on an ASUS EeePC 4Gig Surf. And my first time was because the 32bit AGP DIamond graphics card had zero driver support in XP 32bit.
This happens to be the ongoing problem... Windows stops supporting hardware, gets infected, then is no longer useable.
I tried running Native Access, but it has so many processes that need to also be verified with an okay, and it doesn't work right to try so.
I just installed openshot 3.5 from openshot ppa. (ubuntu 24.04)
$ sudo add-apt-repository ppa:openshot.developers/ppa
sudo apt update
sudo apt install openshot-qt
$ openshot-qt --version
3.5.0-dev
I launch it and get this error:
"Version 0.6.0 is required, but 0.3.2 was detected. Please update libopenshot or download our latest installer."
Can't find the library:
$ sudo apt install libopenshot
E: Package 'libopenshot' has no installation candidate
I'm on 24.04.4 LTS, and window animations randomly stopped working, after I unplugged my hdmi cable for 10 hours.
I plugged it back in in the morning and there was no animation at all.
This is all I know.
I have tried rebooting
Here is some more information, I think.
Window animations, as in, geany effects. Closing a window has an animation. Instead of immidiately dissapearing, the window fades. clicking "show apps" has a fancy animation as well. The apps list comes up from the bottom of the screen, instead of just appearing
None of these are working on my pc.
6.17.0-20-generic
I am running my display like this: pc, soundbar, monitor.
Graphics card: gtx 980
I have checked accesibility. reduce animations is off.
I have checked the terminal redout of that same setting.
Something like "window-animations-enabled:" and it was set to true
UPDATE Upon running the command ununtu-drivers install, my pc is not booting. (Shows white screen with text "oh no something has gone wrong. a problem has occurred and the system can't recover. please contact a system administrator”)

My PC is a Dell Precision m4800. I have just installed Ubuntu on my machine, however the Wi-Fi is not working. It says: No Wi-Fi adapter found. I am new to Linux, and don't know how to diagnosis the issue.
I tried running the following commands.
sudo apt install linux-firmware
sudo apt install broadcom-sta-dkms
Then I rebooted my system, but it is not working. I am not sure if I can use this command, or if I should run another command that is compatible with my PC and corresponding Wi-Fi driver.

I am completely new to Linux dist. coming from Windows 10. I have installed Ubuntu and installed Steam. Almost all the games in my library are not running after installation.
I actually have a dual GPU in my desktop. Both are connected to each other by a card called 'SLI'. First GPU ensures imaging (rendering video). Second GPU ensures mathematical calculations.
I even installed the latest nvidia driver that is listed on the official ubuntu website. I tried via ChatGPT prompts to find a solution but nothing helped.
Can someone please provide support? I am very desperate.
I have installed Ubuntu 24.04.4 LTS Desktop.
I installed the driver with:
sudo ubuntu-drivers install nvidia:535
Further info:
I ran flatpak install org.gnome.Builder on Kubuntu 25.10 before modifying and compiling a GTK3 app. Now most source code file extensions open in GNOME Builder. I'd like KDE Kate back as default to recover my preferred color scheme, custom keybinds, and VI mode. Uninstalling, then reinstalling when I want to work on GTK3 apps, is too inefficient.
Someone said to check xdg-mime query default text/plain and kcmshell6 kcm_componentchooser to set the default text editor, but it's still org.kde.kate.desktop as preferred. I was using a workaround on each of .{css,pl,sh}, right-clicking in Dolphin then going into Properties and changing the "Open with", but today I clicked on a .c file and decided I've had enough.
I'm about to split and loop through grep MimeType= /var/lib/flatpak/exports/share/applications/org.gnome.Builder.desktop to run xdg-mime default org.kde.Kate.desktop "$x", but this might not persist if a GNOME Builder update adds more MIME types. Which command can permanently prevent any specified application from being the first entry in Dolphin's "Open with" list and used by xdg-open?
While playing games on Kubuntu 25.10 and 26.04* (Both fully updated at the time of testing), my primary monitor, the monitor I'm playing on, will lose signal and will require me to turn it off and on again before working. The game still runs while this is happening however and resumes after a power cycle.

Is there a way to fix this? It's really getting annoying and makes me unable to play multiplayer games.
* I upgraded to 26.04 of Kubuntu because Plasma 6.6 fixed a bug that sounded like what I was experiencing, but with a controller plugged in. It did not work, however.
Edit: Changed system info dump to the dump from 25.10
I’m facing a persistent microphone issue on Kubuntu under Wayland. The hardware and ALSA layer appear to work correctly, but browsers fail to create an input stream.
I would appreciate guidance on structured debugging.
Distro: Kubuntu (Plasma)
echo $XDG_SESSION_TYPE → wayland
Audio stack: PipeWire 1.2.7 + WirePlumber
Chipset: HDA Intel PCH
Codec: Realtek ALC257
Output of:
cat /proc/asound/cards
0 [PCH]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0x6001140000 irq 171
During calls, people cannot hear me.
I can hear them perfectly.
Happens in Chrome, Firefox, and Brave.
Sometimes browser shows “Mic not found”.
Happens with and without headphones.
Restarting PipeWire sometimes temporarily fixes it.
Issue is inconsistent.
Output of:
wpctl status
Audio devices:
Built-in Audio detected
Sink and Source both present
Default sink and source correctly set to built-in analog stereo
However, when Chrome is open, under “Streams” I only see:
output_FL
output_FR
There are no input_FL / input_FR streams created for Chrome.
So:
ALSA sees capture device
PipeWire sees source
Default source is correctly configured
Browser does not create input stream
Restarted services:
systemctl --user restart pipewire pipewire-pulse wireplumber
systemctl --user restart xdg-desktop-portal
Verified capture device exists:
arecord -l
Verified duplex profile enabled (Analog Stereo Duplex).
Set default sink/source manually:
wpctl set-default <sink-id>
wpctl set-default <source-id>
Checked in pavucontrol:
Mic visible
Not muted
Volume normal
Disabled ALSA power saving:
Created /etc/modprobe.d/disable-hda-powersave.conf with:
options snd_hda_intel power_save=0 power_save_controller=N
Rebuilt initramfs and rebooted.
Verified xdg-desktop-portal and xdg-desktop-portal-kde are installed.
None of these resolved the issue permanently.
Hardware appears functional.
ALSA layer is functional.
PipeWire source node exists.
Browser does not create capture stream.
Restarting services sometimes restores mic temporarily.
System is running under Wayland.

I run a a few servers, 2 of which have mitmproxy correctly installed. I follow the same process as the other 2 servers on an identical 3rd server, but mitmproxy does not work. I get a TLS error every time. Here's what i do:
sudo apt install mitmproxy
mitmproxy
cd .mitmproxy
mv mitmproxy-ca.pem mitmproxy.crt
sudo cp mitmproxy.crt /usr/local/share/ca-certificates
this process usually works, but is now bugging out. Any way to fix?

What's wrong here? How do I fix this?
I have just installed a Ubuntu-20.04 on WSL2. And I installed a miniconda env with python 3.7, and then I installed opencv-python by "conda install opencv". But when I try the simplest cv2.imshow, it complains below:
cv2.error: OpenCV(3.4.2) /tmp/build/80754af9/opencv-suite_1535558553474/work/modules/highgui/src/window.cpp:632: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'
By the way, I can show plotting window by matplotlib.pyplot after I installed a VcXsrv and export DISPLAY=host_ip_in_wsl2:1.1. And I also make my GPU works after installed Windows 10 November 2021 update, CUDA driver for WSL2, and CUDA toolkit 11.0. I can get Tensorflow 2.4.1 working well with GPU. I can compile darknet with GPU and use it for YOLO v1.
I googled some. They say uninstall opencv and reinstall from channel menpo can do it. But this post is 5 years ago and not for WSL.
I also saw some posts demonstrate a tedious procedure to compile opencv-python from source.
So, how to use opencv-python on Ubuntu-20.04 of WSL2? Easy approaches like "conda install ..." or "pip install ..." is preferred. Compiling from source is also acceptable.
I am hosting an NFS server on my Synology NAS. It is configured via the in-built NFS server under File Services. The configuration options are somewhat limited and I have set 32kb read/write packet size and max NFS version is 4.1.
The /etc/exports entry is:
/volume1/NAS_Andrew 192.168.0.0/24(rw,async,no_wdelay,crossmnt,insecure,all_squash,insecure_locks,sec=sys,anonuid=1024,anongid=100)
My ubuntu client has the following fstab entry:
192.168.0.219:/volume1/NAS_Andrew /mnt/nas nfs nofail,nconnect=16,rsize=32000,wsize=32000,hard 0 0
This resolves to the following entry in /proc/mounts when mounted:
192.168.0.219:/volume1/NAS_Andrew /mnt/nas nfs4 rw,relatime,vers=4.1,rsize=32000,wsize=32000,namlen=255,hard,proto=tcp,nconnect=16,timeo=600,retrans=2,sec=sys,clientaddr=192.168.0.220,local_lock=none,addr=192.168.0.219 0 0
The problem is that when I am writing a large file to the NFS mount, all other filesystem operations within the mount hang.
For example, if I run the following in terminal 1:
time dd if=/dev/zero of=/mnt/nas/testfile bs=16k count=128k
and then run ls -la in terminal 2; the ls process hangs until the dd write is complete.
I believe the issue is limited to the local NFS client because if I run the same ls -la on another server that also has the NFS share mounted - it runs without any hang or issue.
I'm hoping that someone can shed some light as to why the write operation is blocking.
I tried setting nconnect=16 in an effort to increase the tcp connections and allow more than one operation - however this did not work and I suspect nconnect may be limited to cases where multiple network interfaces are available.
I am running Ubuntu 20.04.3 LTS.
Any input is greatly appreciated.

<0>Kernel panic - not syncing: Fatal exception
I need my Ubuntu to be stable as I rely on it heavily for my business and uni. I needed to update my google cloud sdk so I run sudo apt upgrade as I have done for the last year with no issues. After reboot, my dual screen monitor stopped working and the main display freezing and I lost access to my virtualbox.
I am losing about $50 an hour while this is broken so I am happy to pay some one $100US an hour so I can have a stable system again. Is it possible to stop Ubuntu from upgrading the kernel itself?
Really angry actually that Ubuntu would release such a broken and untested kernel on an LTS system.
I am trying to run an application (code-server) as a sudo user. This application is basically allowing me to run Visual Studio Code online. I created the service file as below: (vsc.service)
[Unit]
Description=Running Visual Studio Code Online
[Service]
User=dev001
Group=dev001
WorkingDirectory=/home/dev001/projects
Type=simple
ExecStart=/usr/bin/sudo /usr/bin/vsc.sh
[Install]
WantedBy=multi-user.target
As you can see that the service file has the user and group information.
Here is the script I want to run as a service (/usr/bin/vsc.sh)
cd /home/dev001/projects
code-server -p 80 --allow-http --password somepassword
It runs fine but the problem is that the user who is running the process is still kept as root, but working as dev001. here is the screenshot of the terminal access via the running service:

Please help me if you have any solution to the problem.
Edit 01:
I have taken the nginx help to do a port forward (reverse proxy) to resolve the issue, until code-server gets matured and has the daemonised support for running directly on port 80 or 443. The one benefit I got with this approach is that I am able to install the letsencrypt ssl. so no my environment is all running as I needed to be. There are other issues thought, but they are not related to this thread.
Since a few days ago, I can't boot my computer on ubuntu, I can't even access rescue mode or boot on a liveusb to try to reinstall my os. Windows is booting fine however.
On a regular ubuntu boot some services fail to start and at some point, the boot process simply stops 
When I try to start rescue mode or boot with liveusb, I have other messages like AMD-VI: Completion-Wait loop timed out and iommu ivhd0: Event logged [IOTLB_INV_TIMEOUT device=1b:00.0 address=0x40e596610] or Kernel panic - not syncing: corrupted stack end detected inside scheduler

Computer specs:
I check my hardware (memtest, gpu/cpu stress test, SMART drive check) and nothing is wrong, I even tried another graphics card. I tried to boot with an Ubuntu 16.04 live USB, but it had the same issue. I tried boot options noapic, nolapic without any success, with acpi=off I have the following screen.

I tried to boot with an Ubuntu daily build in order to have the latest kernel, but I had no luck.
I managed to access my terminal, update-grub didn't help, but when I typed sudo apt update I had E: Error reading the CPU table. /usr/share/dpkg/cputable was missing, I copied a version of the file I found in /snap/core18/941/usr/share/dpkg/cputable and now I have E: Cannot find dpkg tuplet or triplet table.
I am getting a kernel panic - not syncing: corrupted stack end detected inside scheduler error message when attempting to install Ubuntu for desktop on a VMware Workstation Pro 11.

Is there any way to fix this?
The default voice as well as all alternative voices are very difficult to understand.
I cannot find any documentation about how this feature is wired up.
I recently upgraded my ubuntu and suddenly lost DNS. By the looks of it, its related to https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1674532. But I cannot run the update to fix the issue because it can't use DNS to conduct the update. Is there any documentation out there on how to get the DNS working again so i can run the update and fix the issue? I have tried changing the DNS server and everything and nothing is working.

I have recently installed Ubuntu 16.04 and it seems to freeze randomly. I tried to check out the the solutions at Ubuntu 15.10 and 16.04 keep freezing randomly but on installing these kernels, I got a kernel panic at boot, so I furthur looked for solutions at Ubuntu 16.04 constantly freezing leading to kernel panic but couldn't figure out how to resolve the problem. Can anyone tell me which exact kernels to install so that both issues (kernel panic and random freezing) is resolved? The kernel that came preinstalled with 16.04 was 4.4.0-21-generic and these are some extra details:
Distributor ID: Ubuntu
Description: Ubuntu 16.04 LTS
Release: 16.04
Codename: xenial
Processor: Intel Pentium CPU N3540 @ 2.16GHz × 4
Graphics: Gallium 0.4 on llvmpipe (LLVM 3.8, 128 bits)
Ram: 4Gb
Os type: 64-bit architecture
Tell me if I need to provide any other details.
