I installed doom-1.10-7.i386.rpm in Fedora Core 1.
I then accidentally erased the two files created during installation:
rundoom and sdoom in /usr/games.

I wanted to reinstall but got the message "package was already installed".
I then deleted all other files created during the installation:

/usr/X11R6/bin/xdoom
/usr/doc/doom-1.10
/usr/doc/doom-1.10/ChangeLog
/usr/doc/doom-1.10/DOOMLIC.TXT
/usr/doc/doom-1.10/README.TXT

/usr/lib/games/doom/musserver
/usr/lib/games/doom/sndserver
/usr/lib/games/doom/sndserver.8bit
/usr/lib/games/doom/sndserver.8bitMono

I still get the message "package was already installed" when trying to reinstall doom.

Any advise would be appreciated.
Alex

isn't there a "force" option or something for rpm? try reading the manpage "man rpm"

Have you tried adding the '--force' flag?

Also,

If you have rpm2tgz and installpkg, have you tried

rpm2tgz doom-1.10-7.i386.rpm

installpkg doom-1.10-7.i386.tgz

?

Thanks for your replies.
I looked up elsewhere and the suggestion was to use
rpm -ivh --replacepkgs < >.rpm
I will try it when I get home.

--force is the same as --replacepkgs.

use rpm -e <package-name> instead of deleting files within the packages.
This should save you this erro no..

Larry,

I ended up re-updating Fedora. Then the install went fine.
However, I learned my lesson and a thing or two about the rpm command.

Thanks for reply
