When I try installing as stated in [https://certbot.eff.org/lets-encrypt/centosrhel7-nginx](https://certbot.eff.org/lets-encrypt/centosrhel7-nginx) I run `sudo yum install certbot python2-certbot-nginx` While installing it throws an error: Error unpacking rpm package python-urllib3-1.10.2-5.el7.noarch error: unpacking of archive failed on file /usr/lib/python2.7/site-packages/urllib3/packages/ssl\_match\_hostname: cpio: rename I even tried installing this separately… `sudo yum install python-urllib3` Running transaction Installing : python-urllib3-1.10.2-5.el7.noarch 1/1 Error unpacking rpm package python-urllib3-1.10.2-5.el7.noarch error: unpacking of archive failed on file /usr/lib/python2.7/site-packages/urllib3/packages/ssl\_match\_hostname: cpio: rename Verifying : python-urllib3-1.10.2-5.el7.noarch 1/1 Failed: python-urllib3.noarch 0:1.10.2-5.el7 Has anyone faced this problem.

The problem is Certbot requires a higher version than the one available for CentOS. The ‘urllib3\<1.23,\>=1.21.1’ distribution was not found and is required by requests According to [https://pkgs.org/download/python-urllib3](https://pkgs.org/download/python-urllib3), the highest version CentOS supports is 1.10.2 This is the version I get when I do a yum install python-urllib3, If I do a yum install python2-urllib3, it gives No package python2-urllib3 available. If I do a pip install urllib3, it installs version 1.25.1 Is it possible to link this to the dependency when I try to install certbot ---

I believe you can either [specify suitable version](https://packaging.python.org/tutorials/installing-packages/#installing-from-pypi) of the package with `pip install` or download the source from the releases page of [https://github.com/urllib3/urllib3](https://github.com/urllib3/urllib3) and build it. ---
