What is It?

OSE software stack.

OSE Linux is a freely downloadable operating system that contains all software that is used regularly at OSE. It is run as a Live USB without the user having to modify or upset their usual operating system in any way whatsoever. This provides access to exactly the same software that we use during workshops and other training sessions - to avoid differences in versions common to different operating systems. During our training sessions, we will use OSE Linux ourselves - so your programs will look exactly like ours. This addresses hours of potentially wasted time due to differences in software or software not working.

OSE Linux also addresses the tens of hours that it would potentially take to download and configure all the software and libraries in common use by OSE. Instead, a single install, taking under half hour of dedicated user time after download, is sufficient to download the entire operating system. This is useful in large-scale collaborative processes - where everyone should use the exact same system to promote a seamless experience.

It is a good practice for OSE Developers to download and use the system to avoid software malfunction, improper settings, and in general the time it takes to download or install various software and its extensions, such as additional workbenches in FreeCAD, browser plugins, etc. OSE uses only open source software to produce all of its work product to facilitate interoperability with a large global team of developers.

Please note that OSE uses a lot of custom software - so please save yourself hours of install time and and just download the prepared OSE Linux. We are doing this to make your life easy. Note also that you should not run OSE Linux in a Virtual Machine, as a Virtual Machine will be much slower at computation intensive tasks such as CAD.

OSE Linux can be used by downloading the ISO, and creating a bootable USB stick. Instead of using one's regular operating system, one can choose - upon startup - to run the OSE Linux operating system from a USB stick, without installing it on one's hard drive. Note that currently you can't save files on the Live Linux - so upload any documents to your log, the wiki, or use cloud-documents where data is not saved locally.

OSE Linux at Workshops

For reasons of software uniformity, we like to use OSE Linux. Our experience with prior workshops at OSE which involve software training was that always there was someone who could not run some software properly, or there would be some differences in the software on different platforms. This typically obstructed smooth progress of everyone following along during software training. For this reason, we like to use OSE Linux live, so that everyone has the exact same copy. All that people need to do is to boot from our USB. Once booted, uniform results are pretty much guaranteed. Thus, we begun using OSE Linux in 2017 as a regular practice during OSE workshops - where participants are instructed to either make their own USB at home - or we provide the USB at the OSE site.

Download and Install OSE Linux Live ISO

Requirements: ISO image, 4 GB USB stick

v1.0 from 2017

Download the .ISO Image file below. You need to install it onto a USB flash drive to create a Live USB.

How to Create an OSE Linux USB in Linux Mint

  1. Download ISO
  2. Right click on it
  3. Select 'Make Bootable USB Stick'
  4. Wriet Image: to - select where to write the image. You should be able to select your USB stick. 8 gig minimum.

How To Create an OSE Linux USB using Ubunutu

Objective: A bootable USB stick that provides the OSE Live desktop, and will run all the OSE programs without touching any existing locally installed OS on the computer. It's a way to test, and use, the OSE programs (3D design, 2D design, video capture and edit, resource management) and not disturb the current computer setup.

1. Download the ISO (See above for current ISO URL)
2. Burn ISO to USB

   For Setting up the USB stick, follow the instructions How_to:Write_Image_to_SD_Card, 
simply swap the word SD for USB. There are no customizations to be made as they are suggested at the bottom, all is working out of the box.

3. Boot your computer with the USB. See OSE Linux#Getting Started

Here is the video HowTo for Ubuntu 16.04 users, GUI version

Insert your USB Stick and determine its device identifier

  1. Insert USB stick
  2. Open a Terminal window
  3. Determine USB stick device ID: `diskutil list`

$ diskutil list
/dev/disk3 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                                                   *16.0 GB    disk3

Create a bootable USB Stick from a hybrid disk image

Using a hybrid ISO disk image is by far the simpler approach as you just overwrite the entire USB stick.

  1. Unmount all partitions on device: `diskutil unmountDisk [Device ID]`
  2. Copy ISO: `sudo dd if=[Path to ISO] of=[Device ID] bs=1048576`
    • Press CTRL+T to send a SIGINFO signal to `dd` to track progress source

$ diskutil unmountDisk /dev/disk3
Unmount of all volumes on disk3 was successful
$ sudo dd if=~/Downloads/ose0.3isohybrid.iso of=/dev/disk3 bs=1048576
2142+0 records in
2142+0 records out
2246049792 bytes transferred in 1841.710284 secs (1219546 bytes/sec)

The partition is automatically marked as as bootable.

Eject USB Stick: `diskutil eject [Device ID]`

$ diskutil eject /dev/disk3
Disk /dev/disk3 ejected

And you're good to go.

Getting Started

Instructions for using OSE Linux for the first time

Booting Up and BIOS Settings

After powering on your computer, but before your normal operating system starts, you can access your boot settings.

Boot target computer from USB Stick

First, configure the BIOS to prioritize booting from a USB drive. In my case, I'm installing on an HP Spectre x360 laptop [3].

  1. Power up HP Spectre x360
  2. Press `F10` to enter the BIOS
  3. Navigate to System Configuration
  4. Select Boot Options
    1. Disable Secure Boot
    2. Enable Legacy Boot
    3. In UEFI Boot Order move USB Diskette to top of list
    4. In Legacy Boot Order move USB Diskette to top of list
    5. Disable 3D Graphic Acceleration
  5. Press `F10` to save changes and exit BIOS

Your system will restart, recognize the USB Stick, and boot its contents.

_For existing Linux systems with a boot manager installed, you may still need to intervene to select an alternative boot option. Press `F9` to enter Boot Options and choose the USB Disk._

Software Tutorials


We are documenting which systems work successfully for Live boot and/or install of the OSE Linux ISO.

Please document 3 things:

  1. Version of the OSE Linux you are trying to boot and/or install - date or link to the download from above. Note that new versions will be published quarterly. It is impotant to keep notes on the specific version that you are using so there is no confusion on which OSE Linux versions are successful
  2. Hardware you are using, such as Dell Precision M6500 Laptop
  3. Operating system that you are using on your hardware - such as Ubuntu 16.04.

To document this for your system, please go to See ISO to USB Install Notes. The test should verify the following specific usage points, and receive "100% tested and working" condition for the ISO to be considered done (ie, for example, we cannot have the Dimension Drawing Workbench not working in FreeCAD. For the specific usage points that are marked "Not Cricital", they do not count in the grading.

  1. Is the time zone set correctly? (Not critical)
  2. Check.png Does Chromium connect to wireless internet without a problem?
  3. Is the version of Arduino 1.6.8 as the default?
  4. Does Arduino IDE upload sample program to the Mega after selecting the correct board and port under Tools?
  5. Is OSE Marlin available within Arduino?
  6. Can you download a file from Part Library on the wiki and open it in FreeCAD?
  7. Does the Exploded Part Animation workbench create part explosions without crashing?
  8. Do files download to the desktop (so a new user can find files immediately without having to find the Downloads folder in the directory structure)?
  9. Can you upload files to the wiki, such as an image?


OSE Linux Development

This section is used by developers making OSE Linux

How To Create the ISO File Using Ubuntu

We are using the customizer by kamilion:
however, there is a problem with the iso creation process: we need to modify the source code, as the kernel download will otherwise fail and disturb the creation of the iso. This has of course to be done before the compiling into a deb file. For that, we have to edit:
/{Unzipped Master}/src/actions/rebuild.py go to the line


and look under it, there should be a line going like

   if config.KERNEL is not default

comment that out (with #) until next else (including the else) and then correct the intendation (as python is very sensitive to that), meaning everything to the next empty line has to be moved left one 4 whitespaces. In the end, it should look like this:

       #if config.KERNEL is not "default" or None:
       #    misc.chroot_exec(('apt-get', 'install', '--yes', \
       #        config.KERNEL, '-q'))
       #else:  # use the kernel the user specified in the config.
       if arch is not "amd64":  # then use the 32bit 'linux-image-generic'
           misc.chroot_exec(('apt-get', 'install', '--yes', \
               'linux-image-generic', '-q'))
       else:  # use the amd64 'linux-signed-generic' for uEFI
           misc.chroot_exec(('apt-get', 'install', '--yes', \
               'linux-signed-generic', '-q'))

for starting the software just type into a console:

   sudo customizer-gui

There most of the things are pretty self-explainatory or described on the github page, we will be using the chroot console to setup our iso. The following commands will setup the system:
Basic Installation of programs

Installing Cura

   apt-get install python-opengl python-serial -y
   wget http://download.lulzbot.com/Software/Cura/Packages/Cura_21.08/debian/stretch/cura_21.08-f2748_amd64.deb (or the most current, check it)
   dpkg -i cura_21.08-f2748_amd64.deb
   rm cura_21.08-f2748_amd64.deb
   printf "\nADD_EXTRA_GROUPS=1\nEXTRA_GROUPS="dialout"\n" >> /etc/adduser.conf 

Install Arduino 1.6.8 (NOT the current)

   wget https://downloads.arduino.cc/arduino-1.6.8-linux64.tar.xz
   tar xvfJ arduino-1.6.8-linux64.tar.xz
   rm arduino-1.6.8-linux64.tar.xz
   mv arduino-1.6.8 /opt
   and add the OSE Marlin to the examples
   cd /opt/arduino-1.6.8/examples 
   mkdir OSE
   download the file in http://opensourceecology.org/wiki/File:OSE_Marlin.zip
   unzip OSE_Marlin.zip and put the contained file called Marlin in the OSE directory, then delete the rest
   Give it the right to access it, with chown or simply: chmod 777 -R OSE (theres no inherent danger from that code when accessible)
   additionally, make sure the last line of the cura setup is run, as this makes the actual communication with the boards possible.

installing inkscape export:

   wget http://bigbluesaw.com/media/BigBlueSawDXFOutput-Version0.2.zip
   unzip -o BigBlueSawDXFOutput-Version0.2.zip -d /usr/share/inkscape/extensions/
   rm BigBlueSawDXFOutput-Version0.2.zip

installing threejs blender addon:

   wget https://github.com/mrdoob/three.js/archive/master.zip
   unzip master.zip
   cp -r three.js-master/utils/exporters/blender/addons/io_three /usr/share/blender/scripts/addons
   rm master.zip
   rm -r three.js-master

jitsi extension:

   nano /etc/chromium-browser/policies/managed/statkey.json

write in there


Custom User settings
Maybe delete some old stuff, like (this will be updated when the iso gets too bloated):

   sudo apt-get purge unity-webapps*

To make the user experience perfect, we need to adjust some user settings for the freshly logged in user. Unfortunately, the user for the live CD is created on the fly, therefore it cannot be preparated. However, it is possible to manipulate every new user that is created by providing their default folders and everything.
This means, we will preparate the user by setting it up: Run the not created ISO by burning it to a stick, hosting it with a vm or similar, and set it up in a way that everything important is added and set. This includes cleaning the desktop and preparing the taskbar, starting Freecad and installing macros and commands there, and prepare Cura to create GCode for the OSE D3D Printer (More details on that is provided on the software list to the specific task). Additionally, the set setup.sh from the arduino folder must be run to make it a valid program for the user.
When that is done, copy the ENTIRE personal folder (including all hidden folders) into a safe place in the network, as the live CD will not remember any changes. A Cloud, NAS, or simply scp will do the job, however remember not to leave traces, like a remembered password or personal data, as they will be replicated to every new User of the ISO!!!
When you did that, copy all those files (the hidden included, better double check) into the (previously emptied) /etc/skel directory of your chroot (you can do that with scp as well as just adding it into the filesystem that is chrooted on the main system).
The skel folder is basically replicated as a blueprint to every new created user, so every setting left there is then carried forward to the new created user. Rebuild the ISO, and you should be done!


This section will enumerate items for OSE Devs to work on for upcoming versions of OSE Linux.

  • Clear repositories for design - distributed and pulled into the OSE distribution as current working design libraries.


We need to build in a simple way to persist data between reboots.

Marcin would like to be able to use OSE Linux full-time, but he would need to have his ssh key, keepass, etc all persisted between reboots. This, in general, is a necessary feature for anything more than "trying out" a distro. Because this data can be sensitive in nature (ie: ssh keys for logging into hetzner2), all persistent volumes should necessarily be encrypted.

The best experience I've had with Persistence in live distros was TAILS. There's no `dd` on the user side. They just go to "Applications -> System Tools -> Configure persistent volume", and set it up with the GUI.

TAILS is based on debian, as is OSE Linux, so I think this is a good place to start looking for how we can enable persistence in OSE Linux:

  1. https://tails.boum.org/contribute/design/persistence/#index3h2
  2. https://git-tails.immerda.ch/persistence-setup

For more info on this implementation, see OSE Linux Persistence

Hashes & Signatures

For every release of OSE Linux, there should be at least the following files in addition to the iso (arch specific) images:

  1. MD5SUMS
  2. MD5SUMS.gpg
  4. SHA1SUMS.gpg
  5. SHA256SUMS
  6. SHA256SUMS.gpg

This follows the standards as used by debian/ubuntu. For example, see the set of release files for ubuntu 18.04 here:

By following this procedure, we would provide a means for our users (after--say--spending many, many hours downloading the iso over a high-packet-loss sattelite internet connection) to validate that there was no corruption before they burn the image to a drive (a simple & fast step that can save days of debugging). Moreover, by releasing a cryptographic signature of these checksum files, we provide a means of authentication.

Note that, following best operational security practices, the cryptographic signature should be made from a subkey that is signed by an OSE primary key. The primary key should be in cold storage and only used on an air-gapped machine to sign subkeys. Those subkeys (which can be rotated) are the keys that are actually used to sign our releases' checksum files. For more information on this, see this TAILS OpenPGP keys doc

OSE Linux Assists in Providing Technical Support

Technical support is a service of huge importance to the OSE community. As a Distributive Enterprise, OSE is interested in self-maintaining technical support base that can scale to millions of users.

To achieve this, part of our strategy is to utilize OSE Linux as an essential aspect of OSE's technical support. This is a managed distribution that works out all software-related issues for the OSE community - by providing a Linux distribution that just works.

Software-related issues stand in the way of seamless, distributed, open source collaboration. Overall, OSE Linux saves the OSE developer/user community thousands to millions of hours of total time that would otherwise be spent with people downloading software and making it work. To address this issue, OSE is proposing that any OSE user or developer obtains a copy of OSE Linux. This allows for a completely uniform way to eliminate all software related issues: improper installs, drivers, libraries, package conflicts, bad settings, security issues, software crashes, updates, and any other software issues. This is done by installing and using an entire OSE operating system, with all software prepared. The goal is to produce a stable and widely accessible system that can be run from a USB or that can be installed as a Multi-Boot System. The release schedule for updates will be quarterly.

Version Change Log
