@rchovan Try installing python-telegram-bot in a virtualenv. This error is usually caused by an old version of urllib3 that is installed by your systems package manager and cannot be replaced with a newer version by pip.

@jh0ker which version of urllib3 do I need ? Currently I have this:
```aptitude show python-urllib3
aptitude show python-urllib3
Package: python-urllib3
New: yes
State: installed
Automatically installed: yes
Version: 1.9.1-3
Priority: optional
Section: python
Maintainer: Debian Python Modules Team [e-mail]
Architecture: all
Uncompressed Size: 245 k
Depends: python:any (< 2.8), python:any (>= 2.7.5-5~), python-six
Recommends: ca-certificates, python-ndg-httpsclient, python-openssl, python-pyasn1
Description: HTTP library with thread-safe connection pooling for Python
urllib3 supports features left out of urllib and urllib2 libraries.

• Re-use the same socket connection for multiple requests (HTTPConnectionPool and HTTPSConnectionPool) (with optional client-side certificate verification).
• File posting (encode_multipart_formdata).
• Built-in redirection and retries (optional).
• Supports gzip and deflate decoding.
• Thread-safe and sanity-safe.
• Small and easy to understand codebase perfect for extending and building upon.

@rchovan urllib3 must be at least 1.10
