Re: Use of dpkg --set-selections is brain-dead?

The man-page for dpkg suggests that Michael's method should have
worked:

dpkg --set-selections
Set package selections using file read from stdin.

Notice that additional parameters are not required, and the input
comes from stdin.

I was talking about "dpkg --get-selections", not "dpkg
--set-selections".

To be more explicit, "3dchess" is currently purged from my system.
Now, watch and be amazed:

# dpkg --get-selections | egrep 3dchess
# dpkg --get-selections 3dchess
3dchess purge
# echo '3dchess install' | dpkg --set-selections
# dpkg --get-selections | egrep 3dchess
# dpkg --get-selections 3dchess
3dchess install
#

You'll note that, even after "3dchess" has been selected for
installation, it will not be listed by:

dpkg --get-selections

because that doesn't list purged packages, even ones ready to be
installed. Instead, you must instead explicitly write:

dpkg --get-selections 3dchess

to verify that the selection status of this package has changed.
