Package: apt Version: 0.5.4 The order of packages in argument list is relevant, how apt builds its dependency tree. Here is an example:
mpiat0201:~# apt-get -u install nvidia-glx nvidia-glx-dev nvidia-kernel-2.4.20.9.p4 Reading Package Lists... Done Building Dependency Tree... Done The following extra packages will be installed: nvidia-kernel-2.4.20.9.athlon The following NEW packages will be installed: nvidia-glx nvidia-glx-dev nvidia-kernel-2.4.20.9.athlon nvidia-kernel-2.4.20.9.p4 0 packages upgraded, 4 newly installed, 0 to remove and 1 not upgraded. Need to get 0B/3464kB of archives. After unpacking 10.7MB will be used. Do you want to continue? [Y/n] n Abort. Because nvidia-glx depends on a meta-package (nvidia-kernel), which is provided by nvidia-kernel-2.4.20.9.athlon and nvidia-kernel-2.4.20.9.p4 it chooses to install the unwanted .athlon package, because the requested .p4 package is at the end of the argument list. mpiat0201:~# apt-get -u install nvidia-kernel-2.4.20.9.p4 nvidia-glx nvidia-glx-dev Reading Package Lists... Done Building Dependency Tree... Done The following NEW packages will be installed: nvidia-glx nvidia-glx-dev nvidia-kernel-2.4.20.9.p4 0 packages upgraded, 3 newly installed, 0 to remove and 1 not upgraded.

Setting up nvidia-glx-dev (1.0.4349-2) ... Now apt doesn't select the .athlon package, because the .p4 packge is in at the beginning of the argument list of the apt-get command line. I think that both invocations of apt should have the same result.
