Greetings back from Pennsylvania!
Package Manager has a mode where it will list all of the files required to install a package. It will also "download only" (not install) the files, but I never can remember where it puts them. For me, it is easiest in a Terminal session. I just create a version-specific folder and "apt-get download <filepath>" each of the files. Of course, this only works for applications in the Package Manager. Once you get the files, the command "gdebi" works great to install everything. Switch over to the "Newbie Questions" forum for more details or assistance on this. Warning: Sometimes the correct repository is no longer available, or has been moved, or is just hard to find. Hello! Good Luck!
Blessings in abundance, all the best, & ENJOY!
