The behavior is correct if potentially unexpected, but it should be documented better. > > 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-'. That is an entirely different command; `aptitude safe-upgrade foo` upgrades (only) `foo`, whereas `apt upgrade foo` first does the normal install argument handling and then runs an upgrade, so `foo` could also be a new package that is not currently installed to hint the solver if it is unable to find a solution. -- debian developer - deb.li/jak | jak-linux.org - free software dev ubuntu core developer i speak de, en
