I Installed electrum following the instructions from https://electrum.org/#download

Install dependencies: sudo apt-get install python3-setuptools python3-pyqt5 python3-pip

Install Electrum: sudo pip3 install https://download.electrum.org/3.1.1/Electrum-3.1.1.tar.gz

OS is linux mint 17

When I click the electrum icon through the applications menu nothing happens. I have electrum-ltc installed and it was working. Since installing electrum it will not run.

If I try to start it through the command line I get the following error:

$ ./electrum

/usr/local/lib/python3.4/dist-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.7.1) or chardet (2.2.1) doesn't match a supported version!
Error: cannot import name 'DependencyWarning'. Try 'sudo pip install <module-name>'

Trying to update urllib3 and chardet I get these errors:

$ sudo pip install urllib3

How can I update urllib3?

Or does the problem have something to do with the dependencies I installed?

"Install dependencies: sudo apt-get install python3-setuptools python3-pyqt5 python3-pip"

Electrum-ltc was working fine before I installed the dependencies above for Electrum (btc).

Your problem is that you have two python installations in your system, python2.7 and python3.4. The pip command refers to the package manager for python2.7, so when you issue pip install urllib3, you're trying to install/update the urllib3 package for the wrong version of Python - use pip3 to install/update packages for Python 3:

$ pip3 install chardet urllib3 --upgrade --user

Btw, I prefer not to call sudo pip/sudo pip3 because some python packages are managed by apt (like pip itself, setuptools or requests), so if you have first installed

$ apt install python3-setuptools

and then start to sudo pip3 install packages, sooner or later you'll break stuff because setuptools is declared as a dependency by many python packages and you will accidentally overwrite python3-setuptools installation. It's safer to sudo apt install and if apt does not provide the package you need or provides an old version of it, then pip install --user it.
