This document describes how to install debug packages on Ubuntu, which will aid in providing information for bugs.

Use this section only if you are using Ubuntu Edgy 6.10. See the following section if you are using a prior version.

1. Add the following line to /etc/apt/sources.list:

}}}

2. Import Martin's public key to your keyring:

wget "http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x0DE7276D5E0577F2" -O - | sudo apt-key add -

3. Then run

to update your package list.

4. 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
```
Now you make a ["Backtrace"].
You can also run ["Valgrind"], if the program crashes with a "Segmentation fault" or "Bus error".
Optionally, you may be asked to produce an ["Strace"].

The steps described above for Edgy also work for Feisty, just add the following line to /etc/apt/sources.list:

}}}

Use this section if you are using an Ubuntu version prior to Edgy 6.10.

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

Install the development scripts:

sudo apt-get install devscripts fakeroot

Find out to which package your program belongs to:
```
dpkg --search <program> 
```
Install the build-time dependencies for the package:
```
sudo apt-get build-dep <package>
```

Build .debs for debugging:

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

Install the needed .debs (they will be in the current working directory if the build succeeded):
```
sudo debi <package>*.changes
```

* Most packages support the build of debugging version in this way. If this process doesn't work for a package, please open a bug against it.
