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/ .

Please help me ! :frowning:

Sorry to hear you’re having trouble. letsencrypt-auto is unable to connect to https://pypi.python.org and is saying the “Network is unreachable.”

What is the output of:

grep -m1 LE_AUTO_VERSION letsencrypt-auto

and of:

PIP_VERBOSE=1 ./letsencrypt-auto certonly --standalone -d mail.domain.com -d mail.domain.id

Dear Mr. Bmw,

Sorry for late reply.

Thanks for your response.

Im tried your solution but still failed :frowning:

This is output :

[root@mail letsencrypt]# grep -m1 LE_AUTO_VERSION letsencrypt-auto
LE_AUTO_VERSION="0.26.1"
[root@mail letsencrypt]# PIP_VERBOSE=1 ./letsencrypt-auto certonly --standalone -d mail.domain.com -d mail.domain.id

You’re getting network errors from yum too. Is a firewall blocking outgoing connections on port 443?

What’s the output of:

  1. curl -L https://pypi.python.org
  2. curl -L https://mirrors.ustc.edu.cn/pypi/
  3. pip --version

#5

Dear Mr. Bmw,

Thanks for your reply.

Port 443 is not blocked.

This is output :

[root@mail ~]# curl -L https://pypi.python.org
curl: (7) Failed to connect to 2a04:4e42::223: Network is unreachable
[root@mail ~]# curl -L https://mirrors.ustc.edu.cn/pypi/
curl: (7) Failed to connect to 2001:da8:d800:95::110: Network is unreachable
[root@mail ~]# pip --version
pip 8.1.2 from /usr/lib/python2.7/site-packages (python 2.7)

Please help :frowning:

Thanks.

It seems like your server is unable to make outbound HTTPS connections, at least to mirrors.fedoraproject.org and the two PyPI mirrors I suggested you try.

@schoen (or anyone else here), are you able to help @arsyam debug their network problems?


#7

Hi @arsyam,

It looks like the problem might be that your server thinks it has IPv6 connectivity, but it really doesn’t.

You could try

curl -4 https://pypi.python.org

to check if this is the case.


#8

Hi Mr. @schoen

I have tried and this is output :

 [root@mail ~]# curl -4 https://pypi.python.org
curl: (7) Failed connect to pypi.python.org:443; Operation now in progress

Whats wrong?

Thanks.

Regards,
Arie


#9

Do you have a firewall that blocks outbound Internet connections from this machine?
