AFAIK apt-get's resolver has always been quite crude and it fits certain use cases, but I'm not aware of its capability to offer alternative solutions which is one of the strengths of aptitude. > > and I'd start with safe-upgrade. > > safe-upgrade will upgrade the packages that do not need removal or > installation of other packages. So this is safe to do, but the OP > will probably not end up with the new KDE then. If packages were automatically installed and are no longer needed, safe- upgrade will remove them. With the safe-upgrade method I have upgraded all available packages, except 3. Two of those are kio-extras and kio-extras-data on which aptitude full-upgrade will suggest to remove plasma-desktop and we'll have to wait a bit longer till various dependencies are available. The only one I did force to upgrade was plasma-framework, as without it I sometimes noticed things not always working properly, like krunner. I solved that by installing plasma-runners-addons and plasma-widgets-addons, which in turn automatically installed plasma-dataengines-addons and kdeplasma- addons-data, all 4 from experimental. After that I could safe-upgrade plasma- framework and I'm running with all the latest packages available on sid, except those 2 earlier mentioned kio related packages. In my experience you can consistently upgrade your system with safe-upgrade and only occasionally you need to force things with full-upgrade. Sometimes that means that not all packages are updated immediately, so you wait a couple of more days till those are also safe-upgrade-able. 9 out of 10 times I conclude that aptitude was/is right not to upgrade all packages immediately :-) HTH, Diederik
