I have a system that is mostly debian testing. But I have apt set up so that apt-get update fetches information about both the testing(woody) and unstable(sid) archives. I have /etc/apt/preferences set up thus:
Package: * Pin: release a=testing Pin-Priority: 900 Package: * Pin: release o=Debian Pin-Priority: -10 I tried to upgrade to the new mozilla by doing: apt-get install mozilla-browser/unstable But apt complained about an un-met dependency (a too-old version of libnspr4). I fixed this by way of: apt-get install libnspr4/unstable after which `apt-get install mozilla-browser/unstable' successfuly installed version 0.9.7 of mozilla from sid. But it seems to me that apt-get did not behave according to expectation here. I thought that: apt-get install mozilla-browser/unstable would automatically bring down the packages from unstable that the version of mozilla-browser in unstable depended on. Was I wrong in this expectation, or is there something wrong with the way that dependencies are calculated for mozilla-browser in the unstable distribution? Jim
