It seems that aptitude is trying to fetch the changelog for the version
of apache2 with the highest version number, which is that in
lenny-backports, but doesn't find it.
Instead, you can 'target' aptitude at a particular release, like this:
$ aptitude -t lenny changelog apache2
That will tell aptitude to look for the official lenny version.
