Upgrade Fedory Core z verze 3 na vezi 4

Díky nástroje pro správu balíku yum můžeme upgradovat celý náš systém na novou verzi za běhu a vzdáleně.

1. Download and install the Fedora Core 4 version of fedora-release from one of the Fedora Core mirrors.

Example:

1. rpm -Uvh http://download.fedora.redhat.com/pub/fedora/linux/core/4/i386/os/Fedora/RPMS/fedora-release-4-2.noarch.rpm

2. Disable third-party yum repositories, if applicable.

In my configuration, I had the Dag, FreshRPMs, and Dries third-party yum repositories enabled. As of 06/15/05, only the Dries repository caused an error message (i.e. it had not been updated with Fedora Core 4 packages or it did not have a Fedora Core 4 directory structure) so I will only disable that repository.

1. echo "enabled=0" >> /etc/yum.repos.d/dries.repo

3. When upgrading to Fedora Core 4, the kernel must be upgraded before the rest of the packages.

1. yum -y update kernel

Otherwise, you may receive the following error message:

--> Running transaction check --> Processing Dependency: kernel-utils for package: kernel --> Finished Dependency Resolution Error: Missing Dependency: kernel-utils is needed by package kernel

4. Disable SELinux, if applicable, and reboot the system to begin using the Fedora Core 4 kernel. I ran into significant problems after this reboot when SELinux was enabled.

To disable SELinux:

1. vi /etc/sysconfig/selinux

Change: SELINUX=enforcing -- or -- SELINUX=permissive

To: SELINUX=disabled

1. reboot

5. Remove the Fedora Core 3 kernel(s) to prevent the aforementioned kernel-utils package dependency error.

1. yum remove kernel-2.6.11\*FC3\*

6. Continue the upgrade to Fedora Core 4.

1. yum -y upgrade

Note: if you receive the following error, import the RPM-GPG-KEY.

warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID db42a60e public key not available for caching-nameserver-7.3-3.noarch.rpm

1. rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY

7. Reboot the system to begin using Fedora Core 4.

8. If applicable, re-enable SELinux by undoing the changes above, and reboot the system to use SELinux.
