How to Download a source package

Sources are normally not installed. You can only install them if you know the package name.


How to find the name of the source package

A source package could generate many .debs. To know the source package name, see the Source: field in the output of


   apt-cache show package_name


Sometimes the SOURCE: field is not present, then you can check using:

   apt-cache showsrc package_name


Downloading with apt-get source

One way to obtain source packages is with


   apt-get source <package name>

A source package is downloaded in the current directory and is not installed (it will not appear in the installed package list), you need not be root to use apt-get source.
