Upgrading Fedora using yum - Fedora 15 Upgrade
Instructions to upgrade using yum
1. Back up your systemBack up any personal data to an external hard drive or to another machine. If there is some unrecoverable error that requires a fresh install, you don't want to lose any data.
2. Read about common problemsFurther down in this page there is a list of common problems for specific versions. Some of them require attention before the upgrade.
General advice on upgrading Fedora can be found on the Upgrading page. You should also read the Installation Guide and Release Notes for the version you plan to upgrade to - they contain important information regarding upgrading issues. Finally, check the list of Common bugs.
3. Clean StuffReview and remove all .rpmsave and .rpmnew files before and after upgrading. (And if you have selinux enabled then remember to check security context if you move config files around.)
Now is a good time to remove packages you don't use - especially non-standard packages.
4. Do the upgradeIf you have 3rd party repositories configured, you may need to adjust them for the new Fedora version. If you switch from one Fedora release to another there is often nothing that needs to be done. If you switch to Rawhide from a standard Fedora release (or vice versa) then most of the time you will need to install the Rawhide release RPMs from the 3rd party repository as well (or the standard ones, if switching back).
Note that the upgrade is likely to fail if there are outdated dependencies from packages not backed by a yum repository or backed by a repository which isn't ready for the new version.
It is a good idea to do the upgrade outside the graphical environment. Log out of your graphical desktop and then
Go to a text console
ctrl + alt + F2(or)
log in as root, and go into runlevel 3
Update yum to latest version available in your Fedora version
yum update yum
Install the new fedora gpg key for the version you are updating toKeys you may find and verify at
https://fedoraproject.org/keysor see a version specific update instructions at the bottom.
Clean the cacheThen remove all traces of the version you are leaving from the yum cache in
yum clean all
Upgrade all packages
yum --releasever=Note: While it is recommended to upgrade to intermediate releases if upgrading from an older releases (for example upgrading from 12-13, then 13-14), depending on what version you are upgrading from, this step may fail with an error about GPG keys being in the wrong format. To overcome this, you can add the "--nogpgcheck" switch to the above yum distro-sync command.
5. Make sure Fedora is upgradedDistro-sync will usually take care of upgrades for the third party repositories you have enabled as well. Confirm with
yum repolistafter the upgrade process is over.
yummight complain about conflicts or requirements. That is probably because you have used non-standard repositories or installed non-standard packages manually. Try to guess which packages cause the problem (or at least is a part of the dependency chain) - uninstall them and try again. Remember to install the packages again if they are essential. Ensure that all (new) essential packages from the new version are installed with
yum groupupdate BaseYou might want to update other groups too, see
yum grouplistFor example
yum groupupdate "GNOME Desktop Environment" \ "Development Tools" "Server Configuration Tools" \ "Hardware Support" "Sound and Video" \ "Graphical Internet" "Fonts" \ "Games and Entertainment" "Printing Software" \ "Administration Tools" "Office/Productivity" "System Tools"
6. Preparing for rebootBefore booting you should usually install the bootloader from your new grub by running
/sbin/grub-install BOOTDEVICE- where BOOTDEVICE is usually
/dev/sda(If you get an error '/dev/sda does not have any corresponding BIOS drive' from that, then try /sbin/grub-install --recheck /dev/sda.)
Also, the order of init scripts could have changed from the previous version. A command to reset the order is:
cd /etc/rc.d/init.d; for f in *; do /sbin/chkconfig $f resetpriorities; doneAgain, run
package-cleanup --orphansto find packages that haven't been upgraded.
Version specific notes
From pre-releaseIf you are upgrading to a final release from an alpha, beta, preview, or other Rawhide release, please see Upgrading from pre-release to final.
To development version
yum update yum yum --releasever=rawhide distro-sync --skip-broken
Fedora 14 -> Fedora 15First install the new fedora 15 gpg key. You may wish to verify this package against https://fedoraproject.org/keys and the fedora ssl certificate.
rpm --import https://fedoraproject.org/static/069C8460.txtUpgrade all packages with
yum update yum yum clean all yum --releasever=15 --disableplugin=presto distro-sync
- Do not run this from within an X terminal. Testing shows that X might hang while updating bitmap font packages.
- There exist .drpms, but they don't match, due to a format change, so better disable the presto plugin.
VirtualBox guest upgradesThe steps above work perfectly for upgrading a Fedora 14 guest to Fedora 15, but you also need to remove the Guest Additions. If you forget, F14 -> F15 upgrades will seem to fail after the first reboot. If that happens, log in to the console with CTRL+ALT+F2 and reinstall the guest additions manually:
mount /dev/cdrom /media /bin/sh /media/VBoxLinuxAdditions.run reboot
