I need to install the package texinfo version 4.11 that I downloaded from http://ftp.gnu.org/gnu/texinfo/ and unpacked (folder texinfo-4.11).
I already installed packages with the 'sudo apt-get install' command in the terminal. However, this does not work with 'sudo apt-get install texinfo-4.11' in the correct terminal location. The following error messages appear:
E: Unable to locate package texinfo-4.11
E: Couldn't find any package by regex 'texinfo-4.11'
