TLP brings you the benefits of advanced power management for Linux without the need to understand every technical detail. TLP comes with a default configuration already optimized for battery life, so you may just install and forget it. Nevertheless TLP is highly customizable to fulfil your specific requirements.

TLP packages are available for Arch, Debian, Fedora, Gentoo and Ubuntu. You're welcome if you want to package TLP for other distributions – please take a look at the TLP Developer Documentation.

Please note: TLP runs on every laptop brand. Setting the battery charge thresholds is available for IBM/Lenovo ThinkPads only.

    Go to Ubuntu Key-server

Code Select Expand

http://keyserver.ubuntu.com/.

Here you can search your key. In my case it was 6AF0E1940624A220.

Note while searching for key pre-append the key with 0x.

So search for 0x6AF0E1940624A220.


    Click on the link provided in the pub section.

This should take you to page containing the key.

It should start with something like Public Key Server -- Get "0x6AF0E1940624A220"


    Copy the whole text from the page and save it in a file(say filename is key1).

    Once you have copied the data to file. Save it. Then run the following command

   

Code Select Expand

sudo apt-key add key1

You will get an "OK" response.

And you are done. Repeat the procedure of other keys that might be missing.
