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.
mv ~/work/desktoploongson_0.1-1_mipsel.deb /usr/local/mydebs/
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.
$apt-get update
$apt-cache search desktop_loongson
