The debug symbol packages have the `-dbgsym` suffix attached, so to install the debug symbols for the package `yelp`, you run:
{{{
sudo apt-get install yelp-dbgsym
}}}

 1. Now you make a ["Backtrace"].
 1. You can also run ["Valgrind"], if the program crashes with a "Segmentation fault" or "Bus error".
 1. Optionally, you may be asked to produce an ["Strace"].

Old notes

  1. Check if the package has a debugging version available. In general, debugging packages will be named with a -dbg suffix

  2. If not, you can generally* build one this way:
    • Something to keep in mind: if you would like to create a build you're going to need to have the relevant deb-src lines in your /etc/apt/sources.list

    1. Install the development scripts: 

      sudo apt-get install devscripts

    2. Install the build-time dependencies for the package: 

      sudo apt-get build-dep <package>

    3. Build .debs for debugging: 

      export DEB_BUILD_OPTIONS="debug nostrip noopt"
fakeroot apt-get source -b <package>

    4. Install the needed .debs (they will be in the current working directory if the build succeeded): 

      sudo debi <package>*.changes

* most of the packages support the build of debugging version in this way. If that doesn't work for a package you can open a bug against it.
