Fetch the only corresponding apt package list immediately after added ppa repo.
Download the released tarball from releases page, extract the files, checkin the directory, and run
make install as root. You can also clone the repo via
git clone https://github.com/PeterDaveHello/ColorEchoForShell.git to get the files.
All the same as add-apt-repository/apt-add-repository(in package:software-properties-common)
apt-get update for the ppa repository after added the repository. So that we don't need to do
apt-get udpate, and can save time and resource because it will only update info about the just added ppa repository.
