[Solved] Python error running letsencrypt-auto

Hi,

Did a quick search and found nothing related.

I installed the letsencrypt client (had to to install virtualenv via pip, too). All I get when running letsencrypt-auto is:

zulu ~/letsencrypt :( #  ./letsencrypt-auto --agree-dev-preview --server https://acme-v01.api.letsencrypt.org/directory auth
Updating letsencrypt and virtual environment dependencies......
Running with virtualenv: /root/.local/share/letsencrypt/bin/letsencrypt --agree-dev-preview --server https://acme-v01.api.letsencrypt.org/directory auth
An unexpected error occurred.

Please see the logfile 'letsencrypt.log' for more details.

Letsencrypt.log shows:

zulu ~/letsencrypt :( # cat letsencrypt.log 
Traceback (most recent call last):

I am on Arch x64.

I am at a loss as to where to start troubleshooting (no experience with Python at all).Is this a problem with my Python environment or something else?

Thanks,

Take a look at #1198. There was a user there that had the exact same problem and resolved it by updating all their packages.

Thanks alot bmw. I solved the issue with that link.
