probleme la startup fedora 12

[epuranhoria]

am incercat yum install nautilus si am primit:---> Package nautilus-extensions.x86_64 0:2.28.4-1.fc12 set to be updated
--> Finished Dependency Resolution
nautilus-2.28.4-1.fc12.x86_64 from updates has depsolving problems
  --> Missing Dependency: libgnome-desktop-2.so.11()(64bit) is needed by package nautilus-2.28.4-1.fc12.x86_64 (updates)
Error: Missing Dependency: libgnome-desktop-2.so.11()(64bit) is needed by package nautilus-2.28.4-1.fc12.x86_64 (updates)
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

 sunt inca nou in Linux si nu prea stiu ce sa-i fac
