Sorry, this might be a beginner question: How can I list all available versions of specific package? I know with apt-get install myPackage=1.2.3 a specific version could be installed. And with apt-show-version -a myPackage I would get a list of versions that are known by the system. But how getting a list of all available versions. I think that isn't possible using the apt tools because they are restricted to configured repositories. So what is the way to go? Some web-repositories? What is the recommondation for Ubuntu 8.04?
