Your sources.list is incomplete. 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.
