also tried this command

/opt/letsencrypt/letsencrypt-auto renew

Error :

Traceback (most recent call last):
  File "/root/.local/share/letsencrypt/bin/letsencrypt", line 7, in <module>
    from certbot.main import main
  File "/root/.local/share/letsencrypt/local/lib/python2.7/dist-packages/certbot/main.py", line 12, in <module>
    import zope.component
  File "/root/.local/share/letsencrypt/local/lib/python2.7/dist-packages/zope/component/__init__.py", line 16, in <module>
    from zope.interface import Interface

I did lot of research no solution found.

Answer 1

After doing lots of research I found it.

You have to unset Python install layout

 unset PYTHON_INSTALL_LAYOUT

then update letsencrypt

 /opt/letsencrypt/letsencrypt-auto -v

Answer 2

sudo pip uninstall zope.interface and reinstall zope.interface

sudo pip install zope.interface

Answer 3

I faced the same issue and upgrading pip and virtualenv as instructed in this post worked for me.

sudo pip install --upgrade pip
sudo pip install --upgrade virtualenv
rm -rf ~/.local/share/letsencrypt
/opt/letsencrypt/letsencrypt-auto --debug

Answer 4

Part of the issue for me was related to some strange default behavior around 64 bit packages installing, but not being picked up by python. After getting this issue [it's mostly installed at this point], run the following [assuming it tries to install in /root/.local/share/letsencrypt/]

cd /root/.local/share/letsencrypt
\cp -r ./venv/lib64/* ./venv/lib/

Then retry the command. The install locations of the python virtual environment change with different versions and operating systems, but the general principle has helped me debug two different installs.
