Certbot has problem setting up the virtual environment

It might automatically be fixed now by pip’s release: https://github.com/pypa/pip/pull/6185, which includes https://github.com/pypa/pip/pull/6171

We also plan to fix Certbot so that it won’t be affected should this happen again: https://github.com/certbot/certbot/issues/6685

So if you manually make the change now, future versions of Certbot will automatically incorporate the change, on our end.

Same error HERE!!!

and fixed with erica’s solution

ty!!!

New install, Ubuntu 16.04 on AWS.
Installed letsencrypt by:

git clone https://github.com/letsencrypt/letsencrypt /opt/letsencrypt

I added the “–no-download” fix to those 2 lines, still fails

Certbot has problem setting up the virtual environment.

We were not be able to guess the right solution from your pip
output.

Suddenly, it worked!

Creating virtual environment…
Installing Python packages…
Installation succeeded.
