Bug#612423: /usr/bin/debdelta: E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages
Package: debdelta
Version: 0.40exp
Severity: important
File: /usr/bin/debdelta
Hi!
Today while trying to run debdelta-upgrade -v I saw this:
debdelta-upgrade : E:Error, pkgProblemResolver::Resolve generated
breaks, this may be caused by held packages.
I have some packages on hold in aptitude (but not in dpkg) and it never
caused any kind of problem (actually debdelta also downloads the deltas
of the packages on hold in aptitude - #544582).
With a simple aptitude full-upgrade:
=
# aptitude full-upgrade

So maybe this situation is somehow confusing debdelta?
