Someone asked, so here's how I transmuted my version of CorelOS to more or less "pure" debian. Though this worked for me, it might be a good idea to read any comments made on this post before doing this, since IANAG (i am not a guru)
1. Establish a net connection, if it's not already up. (i.e., so you can ftp) 2. If you're at not at the command line, go there. Log out of the window manager, and press Ctrl-Alt-F2; you should go from the KDE login screen to a command line login prompt. Log in as root. 3. Remove all packages with the string "corel" in them. You can get a list of these by issuing the command: [1] dpkg --get-selection | grep corel You'll get two columns; the names of the packages you want to remove will be in the left column. Remove them with the following command, as root: apt-get remove pkg1 pkg2 ... where the pkgN's are the names of what you're removing. 4. Edit /etc/apt/sources.list to point to where the new packages are located. If you're not sure, I recommend commmenting out all the lines in there (put a '#' as the first char of the line), then add this line: deb ftp://ftp.debian.org/debian frozen main contrib non-free This will upgrade your system to potato, Debian's 'frozen' release. CorelOS is based on slink, Debian's 'stable' release. If you'd rather update to the latest version of slink, replace the word 'frozen' with 'stable' in the line above. You can then upgrade to frozen from there if you like. I just went straight to frozen with no problems, but ymmv. 5. As root type: apt-get update && apt-get dist-upgrade Your quasi-debian system will start downloading stuff and asking you questions as it installs and configures packages. It may have to download a lot of stuff, especially if you're upgrading to frozen. 6. KDE is now gone (CorelOS comes with a Corelized version of KDE, which you removed a few steps ago). In its stead, I installed gnome. [1] Install the necessary gnome stuff with this command: apt-get install gdm gnome-bin gnome-panel gnome-panel-data gnome-core (that's one long line). That should be it. 'gdm' is the name of the program that provides the nice graphical login. If it doesn't automatically start, start it by typing as root /etc/init.d/gdm start [1] I don't know how to install the non-Corel KDE; if you want that instead, please search the list archives. (http://lists.debian.org/#search -- just search the debian-user list, ignore the 1.4e12 other lists)
