I'm trying to debug some crashes on a 8.04 LTS server, but the ddebs repository at http://ddebs.ubuntu.com/dists/ no longer has a directory for hardy...
Any ideas where the debug symbols for hardy have moved to?
I would open a bug report. Ubuntu 8.04 Server is still supported till April 2013 and being able to debug crashes is crucial after all.
Anyway, if you urgently need packages with debugging information, you can rebuild them like described in this question: How do I rebuild a package to include debugging information?
