You can use the 'find-dbgsym-packages' command from the 'debian-goodies' package to find debug symbols for a core file, running PID or binary path.ДЇor a binary path it only finds debug symbols for the actual binary itself, and not any dynamically linked library dependencies or other libraries loaded at runtime. Chances are that the binary uses shared libraries in other packages and debug symbols for them might be required in order to obtain a readable stack trace or perform other debugging tasks. The above procedure will install the debug symbol package for a single package only. Or sudo apt-get install xserver-xorg-core-dbgsymДЄutomatic Resolution / Installation of necessary packages

If the package in question is the xserver-xorg-core package you can try sudo apt-get install xserver-xorg-core-dbg When a large number of dependancies need to have their symbols retrieved it might become necessary to enable the -dbgsym repositories anyway.Д¬reate an /etc/apt//ddebs.list by running the following line at a terminal: In case the -dbg package is not available for the version of the package you are using, you might have to use the -dbgsym packages. ( the spec for this) Either one of these can be used, but for a given package only one can be used at a time. This is because these packages are used relatively rarely compared to the main repositories and need not be mirrored as much. These are named *-dbgsym.ddeb and are stored in a separate archive. During compilation on the ubuntu servers debug packages are also created automatically for each binary package. However, not all maintainers do this and they may not be up to date. Installing them will just involve finding the appropriate package name based on the version of that is installed. The maintainers of a project usually place the *b packages alongside their binary package in the same repository. The extra information that allows mapping a machine instruction in a complex module to a function and line number in a corresponding C file is stored in the debug symbol packages.

If you want to debug a crash in a project you are developing yourself or from a third-party package, or need the debug symbols for particular libraries very often, it is helpful to install those permanently into your system.Дebugging a program or analyzing stack traces can be very hard because most of the information that can be extracted from them will be in the form of offsets into the binary machine code of the executable. You might need to do this when you are performing tasks like a Backtrace or using Valgrind.
