Hello, Sorry for sending three times and last two times in trouble with ANTISPAM software by other unknow vendor "petsupermarket??" My Fedora Core 4 is upgraded from Fedora Core 3. And xscreensaver failed to upgrade and still stopped at 4.18 and it should be 4.21 in Fedora Core 4 which divided into threee packages. But when I upgrade, it is failed as follows: Dependencies Resolved ============================================================================= Package Arch Version Repository Size ============================================================================= Removing: xscreensaver i386 1:4.18-4 installed 13 M Removing for dependencies: control-center i386 1:2.10.1-6 installed 6.6 M gnome-session i386 2.10.0-2 installed 1.2 M gnome-volume-manager i386 1.3.1-1 installed 737 k Transaction Summary ============================================================================= Install 0 Package(s) Update 0 Package(s) Remove 4 Package(s) Total download size: 0 Is this ok [y/N]: n Do I need to remove the above three packages and resintall them ? Thanks.. Wong Kwok Hon
