		+	===urllib3 or chardet doesn't match supported version===
		+	Overview: When running <code>ansible-playbook</code>, I would get the below error.<br>
		+	Error:
		+	<nowiki>/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.25.10) or chardet (2.2.1) doesn't match a supported version!</nowiki>
		+	Resolution:<br>
		+	<code>__init__.py</code> calls for the following package versions:
		+	<nowiki>urllib3 >= 1.21.1, <= 1.25
		+	chardet >= 3.0.2, < 3.1.0</nowiki>
		+	When I checked, I had the following installed:
		+	<nowiki>~$ sudo pip list
		+	...
		+	chardet (3.0.4)
		+	urllib3 (1.25.10)
		+	...</nowiki>
		+	First I downgraded <code>urllib3</code> to be equal or below 1.25
		+	<nowiki>~$ sudo pip uninstall urllib3
		+	~$ sudo pip install --upgrade urllib3==1.25</nowiki>
		+	This gave me an error citing that:
		+	<nowiki>requests 2.24.0 requires urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1, but you'll have urllib3 1.25 which is incompatible.</nowiki>
		+	So after uninstalling and reinstalling different versions of <code>requests</code>, I found that <code>requests 2.21.0</code> works with versions of <urllib3> below 1.25.0
		+	<nowiki>~$ sudo pip uninstall requests
		+	~$ sudo pip install --upgrade requests==2.21.0</nowiki>
		+	<code>requests 2.21.0</code> installed <code>urllib3 1.24.3</code>, which is fine.<br>
		+	Lastly, <code>ansible-playbook</code> was reporting I had <code>chardet 2.2.1</code> when I really had <code>chardet 3.0.4</code>. I resolved this by removing it and installing the last version.
		+	<nowiki>~$ sudo pip uninstall chardet
		+	~$ sudo pip install --upgrade chardet==3.0.2</nowiki>

 ===Install base packages, independent on package manager===
 The package module can be used to install packages across distributions, but it has some serious limitations when compared to the yum and apt modules, primarily concerning the options to define state, version, etc.
