When the time comes to switch installation media, the installer doesn't let go of the CD-ROM, so the new CD-ROM isn't recognized when it's inserted.
The workaround goes like this:
- When the installer asks for the second CD-ROM, alt-tab to another window, then use ctl-alt-D one or more times to minimize everything
- Launch a shell and issue this command:
sudo umount -l /media/cdrom0
- Eject the CD-ROM and insert DISC 2.
- Go back to the installer window and resume installation.
- When it asks for DISC 1 again, just cancel; I wasn't able to figure a work-around for this one.
- The game is now installed. You'll want to reboot to clean up the CD-ROM mount housekeeping info.
The game worked beautifully for me after installation.
