Not working with certbot python3 version

elvisangelaccio commented 7 years ago

It seems certbot is using python3 nowadays, while certbot-s3front still requires python2 (and installs its files in /usr/lib/python2.7/site-packages/). This is what causes #55

Is certbot-s3front supposed to work with python3?

elvisangelaccio commented 7 years ago

This is the backtrace I get if I try to use python3:

I'm also bitten by this. Any suggestions?

elvisangelaccio commented 7 years ago

@agis As workaround you can create a python2 virtualenv and install certbot/certbot-s3front there.

I have created a python2 virtualenv and installed certbot and certbot-s3front in it.

~However when I run certbot I still get a python3 related problem:~

(venv) ➜  letsencrypt certbot --help
An unexpected error occurred:

Please see the logfile '/var/folders/kx/w2r123xx46jbcq7mhkcs4m1r0000gn/T/tmpas0vjp57' for more details.

Self-solved. It was a weird issue that even if I ran the install using pip2, the certbot was still installed with Python3.6. Cleared my virtualenv and did it again. Sorry for false report

same with python 3.6.3 also requirements pins exact versions of zope.*

ayox commented 6 years ago

I managed to find a solution for this without a virtual enviorment.

You need to uninstall the previous certbot sudo pip uninstall certbot-s3front sudo pip uninstall certbot
Make sure there's no other installtion of certbot on your system cat $(which certbot) | head -1
if you have python 2 installed in your system you can use this command to make sure that certbot runs only with python 2 sudo python -m pip install certbot sudo python -m pip install certbot-s3front

dlapiduz commented 6 years ago

This should be fixed now with the version 0.4.0. Please try it and let me know if it works!

elvisangelaccio commented 6 years ago

@dlapiduz Is 0.4.0 available on pip yet?

dlapiduz commented 6 years ago

@elvisangelaccio oops, there was an issue with pypi and the CI system didn't notify me. It is up now.
