So here you still have the DVDs as your primary archive source, and no
network mirror. This is possible to do, but if for any reason you (or
something you ran where you didn't necessarily know the side effects
of) deleted your /var/lib/apt/lists/ at some point, apt-get update will
not automatically restore the package lists from the CDs.
You have two options:
A. Switch over to use a network mirror for installations. In that case,
remove the cdrom lines (but _only_ the cdrom lines) and add something
like the following to your sources.list:
deb http://httpredir.debian.org/debian jessie main
Then run apt-get update again.
B. Continue using the DVDs, but have APT re-read the lists of packages.
For that, also remove the cdrom lines, and then run the following
command:
apt-cdrom add
It will prompt you to insert the DVD. After it has copied the list
from the DVD and you get the command line back, run it again and repeat
the process for all 3 DVDs. Then run apt-get update again.
After either of these procedures, you should be able to install the
package you wanted to install.
IMPORTANT:
There's a subtle difference between both of the methods: the network
mirrors carry only the _latest_ Jessie point release, which is now
8.4. So if you add a network mirror, there will be a few upgrades
available and you'll upgrade to that next point release. If you stick
with the DVDs, you'll remain on 8.3 with the exception of security
updates, which you have enabled.

This has nothing to do with your problem, but I would not recommend
using wheezy-backports in combination with Jessie. (It shouldn't
hurt, as all packages in wheezy-backports should also be in jessie
in basically the same version, but it's not what you should have
there.) If you need backports _for_ jessie, replace that with
jessie-backports. See http://backports.debian.org/ and
http://backports.debian.org/Instructions/ for details.
