Resources that help to learn to solve Debian packaging problems by example

Hi, 

I'm wondering if there is a central place that I can search for all Debian 
change logs for all packages, to see if the same lintian problem I'm 
having now have been dealt with before, and also see how exactly those 
lintian problems are fixed. 

Thanks
