For two packages, yes, but as you noticed, it grows exponentially with the number of packages. More specifically, the number of dependencies as developped with de Morgan's laws is 2^n here. > There is another solution: Dummy packages (build by xul-ext-adblock-plus) > > Package: xul-ext-adblock-plus > Depends: xul-ext-adblock-plus-iceweasel | xul-ext-adblock-plus-iceape > > Package: xul-ext-adblock-plus-iceweasel > Depends: iceweasel (>= 3.6.13), iceweasel (<< 12.0~a1+) > > Package: xul-ext-adblock-plus-iceape > Depends: iceape (>= 2.1), iceape (<< 2.9~a1+) > > I'm not saying that is the way to do it but it is a possibility. Yes, a possibility which has other interesting advantages, although it may be difficult to implement. > Why does it remove it? Or rather in which situations?

No, you are correct by saying that a simple upgrade or safe-upgrade will not remove it, but holding back a package for that reason is still a problem, and anyway the incompatibility will be problematic for a stable Debian release. -- ,--. : /` ) Tanguy Ortolo <xmpp:tan...@ortolo.eu> <irc://irc.oftc.net/Tanguy> | `-' Debian Developer \_ -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
