All you have are one DVD and the security updates, but not a regular Internet mirror for the rest of the Debian packages that aren't on your DVD. Assuming this machine actually *has* Internet connectivity, what you want to do is add a regular Internet mirror (and then probably also comment out the DVD line, unless you like being prompted to insert the DVD to save bandwidth). For example: deb http://deb.debian.org/debian/ jessie main contrib deb-src http://deb.debian.org/debian/ jessie main contrib deb http://security.debian.org/ jessie/updates main contrib deb-src http://security.debian.org/ jessie/updates main contrib If the machine does *not* have Internet connectivity, then you're going to have to sneakernet the libsybdb5 package onto it manually. Plus any other packages that are needed, but which aren't on your DVD.
