These instructions come from http://askubuntu.com/questions/170348/how-to-make-my-own-local-repository with slight modifications.

1.Install dpkg-dev
2.Put the packages in a directory
3.Create a script that will scan the packages and create a file apt-get update can read
4. Add a line to your sources.list pointing at your repository

Install dpkg-dev

Type in a terminal

sudo apt-get install dpkg-dev

The Directory

Create a directory where you will keep your packages. For this example, we'll use /usr/local/mydebs.

sudo mkdir -p /usr/local/mydebs

Now move your packages into the directory you've just created.

Previously downloaded Packages are generally stored on your system in the /var/cache/apt/archives directory. If you have installed apt-cacher you will have additional packages stored in its /packages directory.

The Script update-mydebs

It's a simple three liner:

#! /bin/bash
 cd /usr/local/mydebs
 dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

Cut and paste the above into gedit, and save it as update-mydebs in ~/bin. (the tilde '~' means your home directory. If ~/bin does not exist, create it: Ubuntu will put that directory in your PATH. It's a good place to put personal scripts). Next, make the script executable:

chmod u+x ~/bin/update-mydebs

How the script works:

dpkg-scanpackages looks at all the packages in mydebs, and the output is compressed and written to a file (Packages.gz) that apt-get update can read (see below for a reference that explains this in excruciating detail). /dev/null is an empty file; it is a substitute for an override file which holds some additional information about the packages, which in this case is not really needed. See deb-override(5) if you want to know about it.

Sources.list

add the line

deb file:/usr/local/mydebs ./

to your /etc/apt/sources.list, and you're done.

CD Option

You can burn the directory containing the debs to a CD and use that as a repository as well (good for sharing between computers). To use the CD as a repository, simply run

sudo apt-cdrom add

Using the Repository

Whenever you put a new deb in the mydebs directory, run

sudo update-mydebs
sudo apt-get update

Now your local packages can be manipulated with Synaptic, aptitude and the apt commands: apt-get, apt-cache, etc. When you attempt to apt-get install, any dependencies will be resolved for you, as long as they can be met.

Badly made packages will probably fail, but you won't have endured dpkg hell.
