Your computer has a list (such as a catalog) that contains all the available software that the ubuntu servers have available...
This (quoted from here
) seems to say that there is a file on my Ubuntu server which lists all available packages (with their version numbers). If so can anyone please tell me where I can find / view this file?
And anyway after running $ apt-get update can I check what version of a particular package would be installed by $ apt-get install ?
