→ Old article about Release 8.5 in the German DELUG edition of Linux Magazine.

Contents

• Version 8.6.1 of KNOPPIX is based on → Debian/stable (buster), with some packages from Debian/testing and unstable (sid) for newer graphics drivers or desktop software packages. It uses → Linux kernel 5.3.5 and Xorg 7.7 (core 1.20.4) for supporting current computer hardware.

• Both 32bit and 64bit kernel supporting both old and new computers, the 64bit version also supporting systems with more than 4GB of RAM and chroot to 64-bit installations for system rescue tasks. The bootloader will start the 64bit kernel automatically if a 64bit-capable CPU is detected (if not manually specified otherwise).
• For Computers that can only start from CD, not from DVD or USB flash pen, a tiny bootable CD image has been placed in the "KNOPPIX" folder, which can be burned and used together with the full USB or DVD version in order to start on old computers.

  • → support for UEFI Secure Boot

Complete software list: -> DVD (~4000 software packages, over 11GB uncompressed, cloop-compressed to 4.7GB standard DVD-size).

partition layouts

With the new Hybrid layout of the ISO file, the file can be copied directly to USB flash disk, either using standard Linux tools like dd or cp, or programs like → Win32 Etcher. In this case, the first partition is read-only because of the iso9660 file system. Because of that, boot options cannot be changed permanently in this layout.

A better way of installing, is using → flash-knoppix, which will create the simpler and writable layout with one FAT32 and one Linux partition on USB flash pen. Optionally, a personal remastering can be chosen in version 8.6.

UEFI Secure Boot

KNOPPIX 8.6 generally supports booting in → UEFI and → Secure Boot after installation on USB flash disk. But in order to use this feature, an entry in the UEFI firmware is necessary at first boot attempt. → Find quick instructions here.

Special Feature "Everything 3D"

"3D Design and 3D printing" is a great field of play for creative persons and makers. Also, many lectures and talks held be Klaus Knopper have touched the topic this year. Because of that, the KNOPPIX DVD version 8.6 features the following popular 3D programs: → OpenScad - 3D construction without drawing skills → Slic3r - G-Code printing preparation for 3D models → Blender*) - extensive 3D modelling and animation program → Freecad*) - Draw 3D models *) Because of space considerations, included inside the second overlay image KNOPPIX/KNOPPIX1

Hints about version 8.6

• The newest 32bit version 2019.* OpenScad is disfunctional, when the system is started with a 64bit kernel. Symptom: After starting edit mode, the main OpenScad window freezes and the program can only be terminated by the task manager or killall openscad.
  → Issue 2933 in the OpenScad github repository.
  In the 8.6 release of Knoppix, the working version 2015.03 of OpenScad, from Debian/oldstable, is installed.

ADRIANE

→ A.D.R.I.A.N.E. (Audio Desktop Reference Implementation And Networking Environment) is a talking menu system, which is supposed to make work and internet access easier for computer beginners, even if they have no sight contact to the computers monitor. A graphical environment with also talking programs and arbitrary magnification using compiz, is another option.

CD / DVD / USB Versions - which files do I need?

The current public beta release of KNOPPIX 8.6 DVD is available in different variants for download at the KNOPPIX-Mirrors.

Caution: Because the DVD image is larger than 4GB, it cannot be stored on a FAT32 partition! -> Use NTFS or a linux file system.

For burning a CD or DVD, only one single .iso file matching your language and version choice, is sufficient.

Additionally, several independent vendors offer readily burned and verified CDs, DVDs and USB-memorysticks sent out via postal service.

Booting from Flash

In order to create a bootable USB-medium (memory flashdisk, SD-card, digital camera with USB connector, cellphone with microSD, ...), the program flash-knoppix can be started from a running KNOPPIX system. This program installs all needed KNOPPIX files onto the FAT-formatted flashdisk, and creates a boot record for it. If desired, the target medium can be partitioned and formatted, or left in its inistal state, so that existing files stay intact. The KNOPPIX Live System starts and runs about factor 5 faster from USB flash disk than from CD or DVD!

After having copied the system to flash, using the persistent KNOPPIX image (overlay feature) or an additional Linux partition, it is possible to also store files permanently in live mode. That way, personal settings and additionally installed programs survive a reboot.

Update: Computers without DVD drive

The flash-knoppix script since Knoppix 7.4.0 supports on-the-fly conversion of a DVD ISO image for direct flashing of a USB pendrive or disk. By using this, the intermediate step of burning a DVD and booting from it, can be skipped. For burning a CD or DVD, only one single .iso file matching your language and version choice, is sufficient. For using this feature, just add the name of the .iso file as commandline parameter to flash-knoppix like this: flash-knoppix KNOPPIX_V8.6.1-2019-10-14-EN.iso

Micro-Remastering

Boot options like "adriane" can easily be preset by changing syslinux.cfg after having copied the CD to a bootable memorystick using "flash-knoppix":

for automatically starting ADRIANE on boot. This is already default in all ADRIANE iso files.

Availability

KNOPPIX 8.6 / ADRIANE 1.7 is available for download via Bittorrent and from the usual KNOPPIX mirror sites.
