pip prints the following errors:
=====================================================

  The repository located at mirrors.aliyun.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS it is recommended to use HTTPS instead, otherwise you may silence this warning and allow it anyways with '--trusted-host mirrors.aliyun.com'.

Certbot has problem setting up the virtual environment.

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

你自己设置的pip.conf有问题，要使用阿里云的pip源的话重新
cat > ~/.pip/pip.conf <<EOF
[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=pypi.doubanio.com
EOF
设置一下pip应该就可以
