Answer 1

You are reading old instructions off the internet. tlp is included in Ubuntu's universe repository so all you need to type is:

sudo apt install tlp

If you want to utilize the Radio Wizard also use:

sudo apt install tlp-rdw

Thinkpad users can install optional packages for battery threshold levels:

sudo apt-get install tp-smapi-dkms acpi-call-dkms
