Ubuntu – Tlp power management

tlp

I have having trouble with tlp power management
I just installed ubuntu 14.04 today

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update

This two commands worked

sudo apt-get install tlp tlp-rdw
sudo start tlp

These commands failed and returned some errors

When I did sudo tlp start and got sudo: tlp: command not found

When I did sudo apt-get install tlp tlp-rdw I got this error:

Reading package lists... 
Done Building dependency tree 
Reading state information... 
Done 
E: Unable to locate package tlp 
E: Unable to locate package tlp-rdw

I have a thinkpad laptop so I also typed this and it worked

sudo apt-get install tp-smapi-dkms

Why can't I run tlp when it loaded from the repository seemed to work

Try this (I have never tried myself and please do it on your own risk):

su

echo "deb http://ppa.launchpad.net/linrunner/tlp/ubuntu trusty main" >> /etc/apt/sources.list

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 02D65EFF; apt-key adv --keyserver 
pool.sks-keyservers.net --recv-keys 02D65EFF

apt-get update

apt-get install tlp tlp-rdw
