Getting error while running certbot command

Is this issue related to python?

My domain is:

I ran this command: # certbot --version

It produced this output:

# certbot --version
Traceback (most recent call last):

It looks like the same dependency conflict reported here:

How did you install Certbot? Did you install it from EPEL as suggested on ?

What does this show:

rpm -q python-urllib3 pyOpenSSL
python -c "import urllib3; print urllib3.__version__"

Thanks for the comment. Yes, I followed the instruction. I will try to reinstall everything and see if it is working.

rpm -q python-urllib3 pyOpenSSL

 python -c "import urlllib3; print urllib3.__version__"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named urlllib3

Sorry, I put one too many l’s there. Could you try it again without the extra one? I edited the earlier post.

I was able to resolve the issue by uninstalling the packages and then re-installing. python-urllib3 was giving problem while installing. So I did below things

1. Uninstall urllib3
2. Again install python-urllib3

pip uninstall urllib3

I did the uninstall/reinstall but now I get this error …

pkg_resources.DistributionNotFound: The ‘urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1’ distribution was not found and is required by requests

Was your installation successful?

There were no errors when I reinstalled using the commands above.

The output from this command follows …
python -c ‘import certbot, requests, urllib3, OpenSSL; print(“certbot :”, certbot.version); print("requests: ", requests.version); print(“urllib3 :”, urllib3.version); print(“OpenSSL :”, OpenSSL.version)’
(‘certbot :’, ‘1.0.0’)
('requests: ', ‘2.6.0’)
(‘urllib3 :’, ‘1.10.2’)
(‘OpenSSL :’, ‘0.13.1’)

My install was messed up because some things were installed with yum, others were installed with pip install and some were installed both ways. Got it to work by uninstalling those items and reinstalling certbot and it’s dependencies just using yum, urllib3 version 1.10.2.
