Certbot: Pip mirror causes problems: could not find a version that satisfies the requirement acme==0.12.0

[cnyyk]

My operating system is (include version):

CentOS 7.3.1611(Core)

I installed Certbot with (certbot-auto, OS package manager, pip, etc):

yum with epel repo.

I ran this command and it produced this output:

certbot-auto renew all

Certbot's behavior differed from what I expected because:

Exception occurs

Here is a Certbot log showing the issue (if available):

You are using pip version 8.0.3, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

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.

Fixed.
The pip mirror caused this issue.
rm ~/.pip/pip.conf
Then certbot-auto renew, works fine!
