1. Update and Install OpenSSH Server in WSL:

Open your Ubuntu 22.04 WSL distribution and Update the package lists.

Code

  sudo apt update

Install the OpenSSH server.

Code

  sudo apt install openssh-server

enable and start the ssh service.

Code

  sudo systemctl enable ssh --now

2. Configure SSH in WSL (Optional but Recommended):

• Edit the SSH configuration file to enhance security (e.g., change the default port, disable password authentication for key-based authentication):

Code

  sudo nano /etc/ssh/sshd_config

• Modify or add lines as needed (e.g., Port 2222, PasswordAuthentication no, PubkeyAuthentication yes).
• Save and exit the file.
• Restart the SSH service for changes to take effect:

Code

  sudo service ssh restart

3. Set Up Port Forwarding on Windows:

• Open PowerShell as Administrator on your Windows host.
• Get the IP address of your WSL instance and set up port forwarding. Replace 2222 with your chosen SSH port if you changed it in sshd_config:

Code

  $wsl_ip = (wsl hostname -I).trim()
  netsh interface portproxy add v4tov4 listenport=2222 listenaddress=0.0.0.0 connectport=2222 connectaddress=$wsl_ip

4. Configure Windows Firewall:

• Open Windows Defender Firewall with Advanced Security.
• Create a new Inbound Rule:
  • Select "Port" and click Next.
  • Choose "TCP" and enter the port number you are using for SSH (e.g., 2222).
  • Allow the connection and apply the rule to all profiles. 
  • Name the rule (e.g., "WSL SSH") and finish the wizard. 

5. Generate and Copy SSH Key (for key-based authentication):

• Generate Key on Client (e.g., your Windows machine or another remote machine):

Instead of using "touch" to create the tape. Which, by-the-by would

not initialize the VOL1 an other header records, I'd use the hetinit

command. You have two choices. AWS format or HET format. hetinit

will create either, but defaults to het. Note also that het

formatted files must end in ".het" to be recognized by hercules as

such.

Notes on installing sabnzb w/o the Ubuntu snap version.

Snap is useless in this use case.  Makes use difficult and unnecessarily so.  this utility was apparently migrated to snap by someone who doesn't use it, or had a usecase in mind different from a desktop single use of it as a use.

 

It unnecessarily runs it in a snap container.  Anything obtained via this utility is as-is whereis by the user.  No execution by any default.  So containing it in a container is useless.

 

Also if it is supposed to be useful as a daemon it isn't very well thought out.  multiple users would have to be given access, and sort out each others download.

 

The use case model is that it's a utility that runs on the users credentials and is present as needed to do its job.  per user.

 

Snap is very annoying and is a poorly thought out solution which found a problem. 

 

To the task at hand.

from:

https://github.com/sabnzbd/sabnzbd/issues/2888

 

AI thumbnail on google answered to query "install sabnzbd ubuntu 25 no snap"

 

Step 1: Add the PPA 

Open your terminal and run the following commands to add the necessary repositories and the PPA. 

• For the most stable release, use the nobetas PPA:
  bash

  sudo add-apt-repository ppa:jcfp/nobetas
   

  If you need beta/release candidates, use this one instead: 

  sudo add-apt-repository ppa:jcfp/ppa
   

Then, update your package list: 

sudo apt update

 

Step 2: Install SABnzbd 

Install the SABnzbd package with the following command: 

sudo apt install sabnzbdplus

Step 3: Start and configure SABnzbd 

• Start the service: Once installed, the service should run in the background by default. You can manage it using systemctl:
  
  

  sudo systemctl status sabnzbdplus.service
  

  Access the web interface: Open a web browser and go to http://localhost:8080 or http://localhost:8080/config to access the web interface. 

Optional: Configure SABnzbd to run as a service 

If you need to manually configure the service, you can edit the configuration file: 

1. Open the file with root privileges:
   sudo nano /etc/default/sabnzbdplus

   2. Set the USER variable and other options as needed.

   3. Save the file and reload the systemd daemon:

     sudo systemctl daemon-reload
   4. Restart the service:

     sudo service sabnzbdplus restart   sudo add-apt-repository ppa:jcfp/nobetas

If you need beta/release candidates, use this one instead:

bash

sudo add-apt-repository ppa:jcfp/ppa

Then, update your package list:

bash

sudo systemctl status sabnzbdplus.service

Access the web interface: Open a web browser and go to http://localhost:8080 or http://localhost:8080/config to access the web interface. 

sudo nano /etc/default/sabnzbdplus

Set the USER variable and other options as needed.

Save the file and reload the systemd daemon:

bash

sudo systemctl daemon-reload

Restart the service:

bash

installing Exagear Desktop on the newer Raspberry Pies

thanks to this guide.

Exagear Desktop is a discontinued piece of software that could be used to emulate x86 applications on ARM devices.

Installation Steps

First install prerequisites with apt

Create a new directory (to download the packages and key)

mkdir ~/exagear
cd ~/exagear

Download and install required Exagear packages (follow the instructions for your bitness)

# 32-bit
wget https://archive.org/download/exagear-desktop_202111/exagear_3428-1_armhf.deb
wget https://archive.org/download/exagear-desktop_202111/exagear-dsound-server_010_armhf.deb
wget https://archive.org/download/exagear-desktop_202111/exagear-guest-debian-9_3428_all.deb
sudo dpkg -i exagear_3428-1_armhf.deb
sudo dpkg -i exagear-dsound-server_010_armhf.deb

install / run arduino ide on ubuntu 22.04

 The raw arduino downloads from the .cc website didn't seem to run.

 There is no install included, just a full running appimage and a zip of the application to download.

the version installed by using apt is of the 1.8, version, very old.  It does run however.  

It does solve something when run.  There is a permission that has to be added, and the app prompts for it.  

Other problem is that xapp library is missing.  That is in the console scroll when you run the app 

the AppImage seems to run once made executable.  It seems to also install the libs once run. 

 There was a complaint  when running the AppImage about xapp library component missing.  W/o installing it the gui doesn't finish running.
