====== Ubuntu - apt - Add local directory to apt sources.list ======

1. Create the directory to put all the deb files, for example /home/foo/debs:

<code bash>
mkdir /home/foo/debs
</code>

----

2. Put all the deb files into the directory:

<code bash>
mv /home/foo/Desktop/*.deb /home/foo/debs
</code>

----

3. Check the current priorities and section for the package, find entry named Section and Priority:

<code bash>
dpkg --info example_1.2.3-1@i386.deb
</code>

<WRAP info>
**NOTE:**  This returns some information including Section and Priority:

Here is some of the info:

<code>
Package: example
Section: editors
Priority: optional
Homepage: http://www.example.com/
</code>

</WRAP>

----

4. Create an override file. 

An Override file is used to override the default Priority and Section setting of the package.

  * An Override file contains 3 columns: Package, Priority, Section.
    * Package is the name of the Package, Priority is low, medium, high or optional and Section is the section to which it belongs.

Example of override file content:

<file>
## Override
#Package priority section
example low editors
</file>

----

5. Create Packages.gz inside /home/foo/debs

<code bash>
cd /home/foo/debs
sudo dpkg-scanpackages . override | gzip -c9 > Packages.gz
</code>

----

6. If you are too lazy to do the override file, you do not have to.  Just change the "dpkg --scanpackages" command above to this:

<code bash>
cd /home/foo/debs
sudo dpkg-scanpackages . /dev/null | gzip -c9 > Packages.gz
</code>

If you follow this path, ignore step 4 and 5.

----

7. Add this line to /etc/apt/sources.list

<code>
deb file:///home/foo/debs /
</code>

----

8. Re-synchronize the package index files from their sources

<code bash>
sudo apt-get update
</code>

----

9. Install your application:

<code bash>
sudo apt-get install example
</code>


<WRAP info>
**NOTE:**  This has just created a local file repository.

  * apt will fetch the deb files from your local file directory also.
