如何获取和修改通过apt-get安装的软件包的源代码？

   source
       source causes apt-get to fetch source packages. APT will examine the
       available packages to decide which source package to fetch. It will then
       find and download into the current directory the newest available version of
       that source package while respect the default release, set with the option
       APT::Default-Release, the -t option or per package with the pkg/release
       syntax, if possible.

       Source packages are tracked separately from binary packages via deb-src type
       lines in the sources.list(5) file. This means that you will need to add such
       a line for each repository you want to get sources from. If you don't do
       this you will properly get another (newer, older or none) source version
       than the one you have installed or could install.

       If the --compile option is specified then the package will be compiled to a
       binary .deb using dpkg-buildpackage, if --download-only is specified then
       the source package will not be unpacked.

       A specific source version can be retrieved by postfixing the source name
       with an equals and then the version to fetch, similar to the mechanism used
       for the package files. This enables exact matching of the source package
       name and version, implicitly enabling the APT::Get::Only-Source option.

       Note that source packages are not tracked like binary packages, they exist
       only in the current directory and are similar to downloading source tar
       balls.

sudo apt-get build-dep <package>  

 dpkg-buildpackage -rfakeroot -uc -b

dpkg-buildpackage -rfakeroot -uc -b
