Problema ao tentar instalar alguns pacotes

Question

Estou tentando executar este código:

sudo apt-get install g++ build-essential autoconf automake automake1.9 cmake doxygen bison flex libncurses5-dev libsdl1.2-dev libreadline-dev libusb-dev texinfo libgmp3-dev libmpfr-dev libelf-dev libmpc-dev libfreetype6-dev zlib1g-dev libtool libtool-bin subversion git tcl unzip 

No entanto, recebo este problema:

Package automake is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'automake' has no installation candidate
E: Unable to locate package automake1.9
E: Couldn't find any package by glob 'automake1.9'
E: Couldn't find any package by regex 'automake1.9'
E: Unable to locate package doxygen
E: Unable to locate package libsdl1.2-dev
E: Couldn't find any package by glob 'libsdl1.2-dev'
E: Couldn't find any package by regex 'libsdl1.2-dev'
E: Unable to locate package libgmp3-dev
E: Unable to locate package libmpfr-dev
E: Unable to locate package libelf-dev
E: Unable to locate package libmpc-dev
E: Unable to locate package libtool-bin

Eu tentei usar sudo apt-get update , mas ainda recebo esse erro! Alguma idéia?

A saída de grep "^deb" /etc/apt/sources.list é:

deb http://old-releases.ubuntu.com/ubuntu/ xenial main restricted multiverse
deb http://old-releases.ubuntu.com/ubuntu/ xenial-updates main restricted multiverse
deb http://old-releases.ubuntu.com/ubuntu/ xenial universe
