The md5sum of your recreated package does not match the md5sum of the package in the archive (according to the package listing downloaded from the archive). Since they both have identical version numbers, apt is (rightly) convinced that your local versions have been corrupted through some mechanism and that it must do a fresh download. An alternative would be to create local repository [0] from your rebuilt packages and pin it to higher priority than everything else. > Potentially this is great because now I have to carry > /var/cache/apt/archives around all the time when I reinstall new systems > and if dpkg-repack would work as advertised (I think ;-) ) then I would > not have to! -Roberto [0] http://familiasanchez.net/~roberto/howtos/debrepository -- Roberto C.
