Hello,

I'm running an obfuscated bridge relay on a Raspberry Pi. I have tried to update obfsproxy to run scramblesuit, as requested on the blog, but I am running into a startup error. I have the latest Tor (compiled from source), and the latest obfsproxy. I have manually specified a password rather than have the system allocate one.

Everything is up to date.

Relevant info:

pi@raspberrypi ~/.tor $ uname -a Linux raspberrypi 3.10.25+ #622 (moved) PREEMPT Fri Jan 3 18:41:00 GMT 2014 armv6l GNU/Linux

pi@raspberrypi ~/.tor $ tor --version Tor version 0.2.5.2-alpha (git-745434d29a92da68).

pi@raspberrypi ~/.tor $ obfsproxy --version 0.2.6

pi@raspberrypi ~ $ python --version Python 2.7.3

A sudo pip install obfsproxy --upgrade command will only update setuptools to 2.2, but obfsproxy stays the same.

Obfsproxy logfile:
