This question already has an answer here:
apt-cache dump returns all information of available packages. In order to get all versions of a certain package the following was tried:
ubuntu@ubuntu-xenial:~$ apt-cache dump | grep -A25 "python-bottle-doc" | grep Version Version: 0.12.7-1+deb8u1build0.16.04.1 Version: 0.12.7-1
but this is not a stable solution as some packages possesses less details then others.
