To upgrade automatically, use MandrakeUpdate.

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.
