[tahoe-dev] Build/run zfec issue

[Paul Rabahy]

Hey,

I'm having some trouble getting tahoe to build/run on an Ubuntu box. I
followed the instructions on
https://tahoe-lafs.org/trac/tahoe-lafs/browser/trunk/docs/quickstart.rst,
but am now getting an error message.

In short, I did the following:
Download
Unzip
python setup.py build
cd bin
./tahoe --version

The error:

Traceback (most recent call last):
  File "/root/allmydata-tahoe-1.10.0/support/bin/tahoe", line 9, in <module>

I tried:
sudo apt-get install python-zfec, but nothing changed.

Any ideas?
