If you want to upgrade manually, download the updated package from one of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". You can download the updates directly from one of the mirror sites listed at: http://www.linux-mandrake.com/en/ftp.php3. Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Mandrake Linux 8.0, look for it in "updates/8.0/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them. Please be aware that sometimes it takes the mirrors a few hours to update.
