Devuan GNU+Linux is a free software operating system for your computer. Free software means you are free to use, copy and distribute, study, change the software, and share your modifications with the community.


General information

This page provides general usage and information about Devuan. These are the basics that everybody should know if they want to use Devuan, and is intended to be suitable for anybody not already familiar with Debian.

Differences from Debian

Devuan removes systemd as the default init, and does not rely on systemd-shim to avoid using systemd. As of the Ascii release we are using eudev as the default device manager instead of udev, as it’s now part of the systemd sources. We also include some custom changes of our own, such as artwork and theming, free software developed within our community and some packages suitable for our user base.

Getting and verifying installation images

Find and download your image(s) from files.devuan.org or one of the mirrors. You should also download the SHA256SUMS and SHA256SUMS.asc files from the same directory as the images.

First verify the integrity of the image(s).

user@GNU/Linux:~$ sha256sum --ignore-missing -c SHA256SUMS

You will now need to get the Devuan developers signing keys and import them.

user@GNU/Linux:~$ gpg --import devuan-devs.gpg

Now verify the SHA256SUMS file is the one signed by the Devuan developers.

user@GNU/Linux:~$ gpg --verify SHA256SUMS.asc

If the signature is reported as good then you can write the image(s) to your bootable media.

Writing an image to bootable media

All Devuan ISO images are hybrid ISOs and may be written to a USB drive using dd.

root@GNU/Linux:~# dd if=filename.iso of=/dev/sdX bs=1M && sync

If you don’t have a spare USB drive you can write the image to a CD or DVD using wodim.

user@GNU/Linux:~$ wodim dev=/dev/sr0 -eject filename.iso

Embedded images

If you want to write an embedded image to an sdcard you will need to install the xz utility.

root@GNU/Linux:~# apt-get install xz-utils

Decompress the image.

user@GNU/Linux:~$ xz -d <filename>.img.xz

Then write it to the sdcard.

root@GNU/Linux:~# dd if=filename.img of=/dev/sdX && sync

Changing the BIOS boot order

In order to boot from your new install media you will have to change the BIOS boot order. It’s not possible to cover the exact steps for doing this as every BIOS is different. You need to enter the BIOS or UEFI interface and change the boot order so that CD/DVD-ROM or USB drives come before hard disk drives. Entering the BIOS is usually as simple as pressing the Delete key before POST.

Install guide

The friends of Devuan wiki has an install guide you can follow for installing from your bootable media. As always remember to backup your data first!
