sudo aptitude upgrade fails and
sudo aptitude upgrade --full-resolver then wants to remove about 100 Packages, because of "dependecy conflicts".
Often I can then start
update-manager and it offers me a "Teilweise Systemaktualisierung" (roughly "partially distribution upgrade"), when I run this then all packages are updated and it does this without removing any packages in most cases.
Since I want to avoid using graphical tools for this kind of stuff, my question is: is there a way to start the "partially dist-upgrade" via command line? Prefferably with aptitude?
