This is completely wrong.
Dselect can only change the desired status of a package to:
desired status keystroke in dselect's "select" point
-------------- -------------------------------------
install +
remove -
purge [1] _ (underscore)
hold [2] =
[1] remove also the config files
[2] usefull when you want to assure that dselect won't alter the
status automaticly (like this is done if you do "update" in dselect and a
package is a "required" package for example).
When you exit the "select" stage, you can do:
1. "install" -> dselect calls dpkg, which will install all files which
have the desired status "install"
2. "configure" -> dselect calls dpkg, which will configure all packages
of the status unconfigured (due to a dependency problem
in a prior run of install for example)
3. "remove" -> dselect calls dpkg, which will remove/purge all packages
which have the desired status of remove/purge
So if dpkg starts to remove all packages you have installed, they have
been marked with "remove" or "purge".
As someone said before, you most likely pressed - or _ on one of the
"headers" like "up to date packages".
