This is a short summary of installing ChaosVPN on Raspberry Pi running Raspbian. (based on the Generic HowTo)
Latest successful with Raspbian Stretch in March 2018.
There is NOT a package for Raspbian, so you have to create your own one.
# apt-get install tinc iproute # apt-get install build-essential git-core bison flex libssl-dev zlib1g-dev # apt-get install devscripts
# git clone git://github.com/ryd/chaosvpn.git # cd chaosvpn
The Generic HowTo say: Answer the "This package has a Debian revision number but there does not seem to be an appropriate original tar file or .orig directory in the parent directory" with "y", but in my case there was no question!
Ignore the message debsign: gpg error occurred! Aborting. ... running debsign failed at the end, that is only for signing the created package.
# sudo dpkg -i ../chaosvpn_*.deb
Thats all. Done in less than 10 minutes.
