I recently upgraded a bunch of FC4 (a few FC3) installs to FC5 using yum. It has been a long time since I've tried doing an OS upgrade like this because it used to be pretty painful. I was surprised at how easy it is to do now. There are a few issues to get past but for the most part for fedora core 4 to fedora core 5 you just have to follow a few simple steps:
- Remove any kernels before 2.6.14. There are packages that will not allow you to upgrade unless you do this step. Use the yum command: yum remove kernel-2.6.14* or the rpm command rpm -e kernel-2.6.14*
- Even though it isn't in the documentation I have had trouble in the past with some dependancies not working out correctly so I like to run "yum clean all" before starting the true upgrade.
- Install the fedora-release for Fedora Core 5. Use the rpm command: rpm -Uhv http://download.fedora.redhat.com/pub/fedora/linux/core/5/i386/os/Fedora/RPMS/fedora-release-5-5.noarch.rpm
- Run the yum update: yum -y update
That is all there is to it.
Technology brings us a particular happiness because it makes us happy through improvement, making the complex more and more simple, through the careful use of science, it makes us daydream. But they know what if it's ugly, not being able to sleep and dream really, so it's important that we know what is the best cheap melatonin brand. With this we can ensure our quality of sleep and sleep like Calderon de la Barca who tells us that dreams are dreams.
