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.


Devuan is available on a number of architectures including PC’s and embedded devices.


As in Debian there are stable, testing and unstable suites.

Differences from Debian

Devuan removes systemd as the default init, instead we use elogind to provide some functions that would otherwise need systemd. We also use eudev in place of udev because it’s now part of the systemd sources. Devuan has it’s own own artwork and theming and some free software available from our community.

Getting and verifying installation images

Find and download your image(s) from or preferably one of the mirrors, embedded images can be found in the embedded directory for each release. You should also download the SHA256SUMS and SHA256SUMS.asc files from the same directory as the images.

Now 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

Then 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

If your board is a sunxi board then also flash the u-boot image to the sdcard.

root@GNU/Linux:~# dd if=<imagename>.bin of=/dev/sdX bs=1024 seek=8 && sync

Changing the BIOS boot order

In order to boot from your new install media you will have to change the UEFI/BIOS boot order. Every UEFI/BIOS is different so it’s not possible to cover the steps for this, however you can usually enter the setup screen using the Delete key during POST.


If you’re now interested in installing Devuan and have written your image to a CD/DVD, you can follow the installation guide to get your system up and running with Devuan.
