43 | ||
44 | dpkg let packages disappear then they have no files any longer and | |
45 | nothing depends on them. We need to collect this as dpkg as well as | |
46 | APT doesn't know beforehand that the package will disappear, so the | |
47 | only possible option is to tell the user afterwards about it. | |
48 | To enhance the experience we also try to forward the auto-install | |
49 | flag so the disappear-causer(s) are not autoremoved next time - | |
50 | for the transfer to happen the disappeared version needs to depend | |
51 | on the package the flag should be forwarded to and this package | |
52 | needs to declare a Replaces on the disappeared package. | |
53 | \param pkgname Name of the package that disappeared | |
