-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi all, i'm currently in the process of splitting a package i'm co-maintaining into several sub-packages. unfortunately i experience some problems with test upgrades, which i would like to solve. the original package "gem" has been split into "gem" and "gem-doc". "gem-doc" contains documentation, that is also of (limited) use if the main package "gem" is not installed. i read [1] and tried to follow it closely, so i end up with a debian/controls file: <snip> Package: gem Recommends: gem-doc [...] Package: gem-doc Section: doc Recommends: gem Replaces: gem (<< 0.93) Breaks: gem (<< 0.93) </snip> obviously, 0.93 is the new version with the split packages (the old one is 0.92) now here's the weird thing: when i upgrade the package using "dpkg -i", success depends on the order of the packages passed to dpkg. that is, if i install it with "dpkg -i gem gem-doc" everything works fine (the old version of gem is removed, the new version of gem is installed and then gem-doc is installed) however, if i run "dpkg -i gem-doc gem" it bails out, as gem-doc (==0.93) tries to overwrite files in gem(==0.92). hein? what will happen if the user wants to do a simple upgrade (e.g. via aptitute)? afaict, there is no way to force front ends like aptitude to install the selected packages in a given order. at least, without resorting to "Breaks", which is actively discouraged on [1] for the purpose i'm pursuing. i can't believe that i triggered a bug, so there must be something wrong. any ideas? fgamsdr IOhannes [1] http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces [2] here's the output of an upgrade process when i first install gem and then gem-doc:: zmoelnig@ferrari:/tmp/debian$ sudo dpkg -i gem_0.93.3-1_i386.deb gem-doc_0.93.3-1_all.deb (Reading database ... 418116 files and directories currently installed.)
