=====================================================
Certbot has problem setting up the virtual environment.
We were not be able to guess the right solution from your pip
output.
Consult https://certbot.eff.org/docs/install.html#problems-with-python-virtual-environment
for possible solutions.
You may also find some support resources at https://certbot.eff.org/support/ .
Let's Encrypt SSL Certificate create failed!
然后我测试手动更新证书/bin/certbot renew --disable-hook-validation --renew-hook "/etc/init.d/nginx reload"
也是一样的错误
我之前的网站，在11月22日，还正常自动更新过证书，11月份来我没进行服务器任何操作，不知道是我的服务器问题还是Let'sEncrypt又有新更新 问题解决pip.conf更改源解决；
阿里云主机更换为 https://mirrors.aliyuncs.com/pypi/simple/都不用下载
非阿里云可以更换为 https://mirrors.aliyun.com/pypi/simple/
当然还有其它的，我没测试 https://bbs.vpser.net/thread-16881-1-1.html#pid52610
