Please help me installing letsencrypt on Ubuntu 16.04


Hi there

I followed all the steps from the article below to install and start SSL for my website,

In the step3, I entered
"./letsencrypt-auto --apache -d mydomainname"

I got an error below.

Checking for new version…
Creating virtual environment…
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/”, line 2363, in
File “/usr/lib/python3/dist-packages/”, line 719, in main

% (cmd_desc, proc.returncode))
OSError: Command /home/christian/.loc…ncrypt/bin/python2.7 - setuptools pkg_resources pip wheel failed with error code 1

Any suggestions to solve the problem?
Thank you.


Hi :slight_smile:

First result on search engine with your error message setuptools pkg_resources pip wheel failed with error code 1 returns this fix.

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"

Maybe change the language according to your preferred one.

Does it solve the problem ?


Oh… that solved the problem.
I was in the wrong page. I opened up all the cnf or/and ini files of python and set the locales but i was wrong.

Thank you very much!
