If you are installing on Debian, you don't need to download these images. Instead read instructions on setting up FreedomBox on Debian.
Recent images for supported targets are available here:
Official Images: http://ftp.skolelinux.org/pub/freedombox/
Unofficial Images: http://compcube.info/wiki/FreedomBoxImages/
Verifying the Downloaded Images
It is important to verify the images you have downloaded to ensure that the file has not be corrupted during the transmission and that it is indeed the image built by FreedomBox developers.
First open a terminal and import the public key of the FreedomBox developer who built the images:
$ gpg --keyserver x-hkp://pool.sks-keyservers.net --recv-keys 0x36C361440C9BC971
- Next, verify the fingerprint of the public key:
$ gpg --fingerprint 0x36C361440C9BC971 pub 4096R/0C9BC971 2011-11-12 Key fingerprint = BCBE BD57 A11F 70B2 3782 BC57 36C3 6144 0C9B C971 uid Sunil Mohan Adapa <email@example.com> sub 4096R/4C1D4B57 2011-11-12
Finally, verify your downloaded image with its signature file .sig. For example:
$ gpg --verify freedombox-unstable_2015-01-15_beaglebone-armhf-card.tar.bz2.sig freedombox-unstable_2015-01-15_beaglebone-armhf-card.tar.bz2 gpg: Signature made Thursday 15 January 2015 09:27:50 AM IST using RSA key ID 0C9BC971 gpg: Good signature from "Sunil Mohan Adapa <firstname.lastname@example.org>" gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner. Primary key fingerprint: BCBE BD57 A11F 70B2 3782 BC57 36C3 6144 0C9B C971
Installation and Use
After the download you can use the image to boot supported hardware (including virtual machines). The hardware devices usually use SD Cards to boot from. To copy the downloaded image to your SD card use a command like this (adapt the if= and of= part to match your image and SD Card path):
$ dd if=freedombox-unstable_2015-01-15_dreamplug-armel-card.img of=/dev/mmcblk0
That's all, you can now start to use your FreedomBox!
