One of the last YaST2-ncurses packages renders YaST2 online update and software management in SuSE Linux 11.2 unusable. Online update just exists back into the menu. If you want to fix it, follow these instructions: 

  • Mount your install DVD. In my case it looks like:
    mkdir /mnt.dist
    mount -o loop /mnt/distro/opensuse-11.2-x86_64.iso /mnt/dist
  • Change path to RPM packages location. In my case:
    cd /mnt/dist/suse/x86_64
  • Restore original packages. In my case:
    rpm -Uvh --force yast2-ncurses-pkg-2.18.4-2.9.x86_64.rpm
    rpm -Uvh --force yast2-ncurses-2.18.10-2.1.x86_64.rpm

That's all. Now you can use online update. It will propose you yast2-ncurses fix, which you should install.
