To update software on your blackdog device, you use the apt utility. The apt utility allows you to download and automatically install software updates on the BlackDog. Refer to the
Debian Apt HowTo page at http://www.debian.org/doc/manuals/apt-howto/index.en.html
for additional information on the apt utility.
The apt utility needs to cache meta-data for proper operation. This meta data is a local cache of packages available on the server, with the interdependencies of these packages. You must update this information periodically for proper apt functionality. The server is the public BlackDog apt server (http://apt.projectblackdog.com/device), configured at /etc/apt/sources.list.
To update this cache meta-data, run the following command on your BlackDog device:
apt-get update
After the meta data has been cached, you can search for packages using the following command:
apt-cache search regular_expression
After you have located the package(s) in which you are interested, run the following command to install them on the BlackDog device:
apt-get install package
The package and any required dependencies will be installed on your BlackDog device.
To download any of the source code for packages installed on your device, run the following command:
apt-get source package
At any time, you can upgrade your BlackDog device's software by running the following command:
apt-get upgrade
This will upgrade all of software on your device to the latest version available.
Note: Periodically, you should run 'apt-get clean', which will delete all of the packages downloaded during an install or upgrade operation.
