I don't understand how this can possibly fix the reported problem, but
anna should not upgrade already installed udebs to newer versions in the
archive. To do so _will_ introduce other bugs, because udpkg does not
support proper upgrading of packages. A few of the potential problems
include, but are not limited to:
- Upgrading a package that provides a file that was also provided by
some other package, thus leaving us with the wrong version of the
file.
- Text file busy. udpkg does not move files out of the way like dpkg
does, so this can occur during an upgrade.
- Lack of versioned dependencies and conflicts in d-i make it impossible
to ensure that the upgraded system is internally consistent.
Not upgrading udebs in the running system is a longstanding design
decision of d-i, and changing this behavior now will break things.
