I do not know what the bug here is, it could be one of these options: 1) apt-get/apt upgrade accepts packages to upgrade where the docs state it doesn't. The behaviour needs to change to not accept packages. 2) apt-get/apt upgrade accepts packages and removes packages to satisfy deps where the docs state it doesn't. The behaviour need to change to not remove any packages. There is a small edge case where you can say: `apt upgrade foo bar-'. Technically, it shouldn't remove packages, yet you want and instruct it to remove bar. FWIW, aptitude does not remove packages where you call `aptitude safe-upgrade foo'. It does remove packages when you call `aptitude full-upgrade foo'. It also removes bar when you run `aptitude safe-upgrade foo bar-'. I'll leave this for the maintainers to answer. Cheers, Wesley
