Upgrading Fedora Using Yum
The recommended installation method is with a boot media with the Anaconda installer as detailed in the Installation Guide. PreUpgrade is a slightly different upgrade method where the all packages are downloaded before the system is rebooted into the Anaconda installer.
When upgrading with yum you don't get any help from Anaconda, but if you are lucky you might be able to upgrade systems remotely over ssh and without any downtime. But the system must be rebooted to get the new kernel and system libraries and services running, so currently you can't avoid having some downtime. Rebooting after such an upgrade is always very exciting.
With a typical installation and when following advices here, then live upgrade with yum usually works well.
Participate
If you are upgrading using Yum and it shows up any general dependency issues, please file them in http://bugzilla.redhat.com. But please read this page and all references pages and search the mailing list archives before filing bugs. And of course, please help keeping this page updated.
If you want to help make live upgrades work smoothly, join the SIGs/LiveUpgrade Live Upgrade Special Interest Group.
Instructions to upgrade using yum
0. Back up your system
Back 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.
1. Read about common problems
Further down in this page there's 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 DistributionUpgrades. You should also read the release notes for the version you upgrade to (for example Fedora 9) - it contains important information regarding upgrading issues.
2. Clean Stuff
Review 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.
Make sure you have the yum-fastestmirror
package installed so that yum uses the "best" mirror.
yum install yum-fastestmirror
Then remove all traces of the version you are leaving from the yum cache in /var/cache/yum
.
yum clean all
3. Switch repositories
Update the packages that decide which yum repositories to use.
rpm -Uhv ftp://download.fedora.redhat.com/pub/fedora/linux/releases/<ReleaseNumber>/Fedora/<Arch>/os/Packages/fedora-release-*.noarch.rpm
For Fedora 9, as an example,
rpm -Uvh ftp://download.fedora.redhat.com/pub/fedora/linux/updates/9/i386.newkey/fedora-release-*.noarch.rpm
(The architecture doesn't matter for this noarch
package.)
Make sure the new repo files isn't placed as .rpmnew
files, perhaps by
mv /etc/yum.repos.d/fedora-updates.repo.rpmnew /etc/yum.repos.d/fedora-updates.repo mv /etc/yum.repos.d/fedora.repo.rpmnew /etc/yum.repos.d/fedora.repo
If you have 3rd party repos configured then enable their repositories for the new Fedora version. If you switch from one Fedora relase to another there is often nothing that needs to be done; is you switch to rawhide then you most of the time need to install the rawhide release rpms from the 3rd party repo as well.
Note that the upgrade is likely to fail if there are outdated dependencies from packages not backed by a yum repo or backed by a repo which isn't ready for the new version.
4. Do the upgrade
If using selinux make sure it is in permissive mode - neither disabled nor enforcing.
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 + F1
log in as root, and go into runlevel 3
telinit 3
Upgrade all packages with
yum upgrade
yum
might 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 is installed with
yum groupupdate Base
You might want to update other groups too, see
yum grouplist
For 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"
5. Preparing for reboot
Before booting you should usually install the bootloader from your new grub by running
/sbin/grub-install BOOTDEVICE
- where BOOTDEVICE usually is /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; done
Again, run package-cleanup --orphans
to find packages that hasn't been upgraded.
Version specific notes
Fedora 9 -> Fedora 10 Beta
- Check the Fedora 10 Beta Release Notes
- GDM starts on tty1 by default, not tty7.
- anaconda by default now refers to encrypted devices by UUID, not by device name, to better handle device name changes. An encrypted device using partition
/dev/sda1
with UUID12345678-1234-1234-1234-123456789012
would now be called/dev/mapper/luks-12345678-1234-1234-1234-123456789012
instead of/dev/mapper/luks-sda1
. You may wish to make the same changes on your system on upgrade; if you do, make sure to runmkinitrd
afterwards. - If you use non-root encrypted devices, you will need to re-run
mkinitrd
for any older kernels that you want to still boot on the system.
Fedora 8 -> Fedora 9
- If you are running as a
xen
Host (Dom0) you should not upgrade to Fedora 9. [1] - Upgrading the thunderbird package will fail . The current workaround is
yum remove thunderbird; yum install thunderbird>
. - If you are upgrading to Fedora 9 and use
emacs
, you must upgrade to the latest version ofemacs
for your prior release to ensure a clean upgrade. Fedora 8 users must haveemacs-22.1-10.fc8
or later, while Fedora 7 users must haveemacs-22.1-7.fc7
. Bug report here . - Due to the switch from sysvinit to Upstart , it is recommended that users who do an upgrade on a live filesystem to Fedora 9 reboot soon afterwards. If you do not reboot, you may want to take careful note of any '/etc/inittab.rpmsave' or '/etc/inittab.rpmnew' files. When rebooting after an upgrade then be aware that sysvinit that was used to start the system can't be used to shut it down.
Fedora 7 -> Fedora 8
- New pulseaudio and flash support packages must be installed manually:
yum groupinstall sound-and-video gnome-desktop (if you are using Gnome) yum groupinstall sound-and-video kde-desktop (if you are using KDE) yum install libflashsupport paman padevchooser
- The Fedora 7 avahi packagage fails to uninstall; remove it manually with
rpm -e --noscripts avahi-0.6.17-1.fc7
- On 64 bit machines (x86_64) you may have to remove some 32 bit libraries. For example dbus:
yum erase dbus.i386
- You may find it easier to use the yum shell to stack these commands in a single transaction:
yum shell > erase dbus.i386 > update > run
- A lot of KDE packages are no longer multilib in F8. If you are on x86_64, you will need to erase the i386 versions of these packages by hand, like so:
yum erase kde{accessibility{,-devel},base,edu,graphics,multimedia{,-extras},network,sdk,utils{,-devel},webdev}.i386
- Various other packages including Beryl are no longer in F8 and not obsoleted:
yum erase beryl\*
Fedora Core 6 -> Fedora 7
- Fedora 7 replaces the old IDE subsystem with libata. Drive device names which previously started /dev/hd.. will become /dev/sd.. after the upgrade. /dev/hda1 will usually become /dev/sda1, although there may not be a direct relationship between the old and new device names (for example hdd does not necessarily become sdd). Before you reboot be sure to change all references to /dev/hd.. in your config, especially /etc/fstab - where it however may be simpler to refer to filesystems by label (check out the programs blkid, tune2fs, and mlabel). LVM Volume names are not affected. In /boot/grub/device.map change /dev/hd.. to /dev/sd.. before running grub-install - and don't change (hd0). Changing /boot/grub/grub.conf may also be required.
- The libata layer represents all hard disks as SCSI disks, which are limited to 15 partitions in the kernel. IDE hard disks with more than 15 partitions are not supported in Fedora 7.
- On a system which has been upgraded from releases prior to FC6 you may need to remove up2date and rhnlib
rpm -e rhnlib up2date
- If you see the message
package gpm-1.20.1-84.fc6 (which is newer than gpm-1.20.1-83.fc7) is already installed
when performing ayum update
uninstall and reinstall the gpm package.
- If you had installed Suns jre it might be removed during upgrade. Be aware that
jre-6u1
/jre-1.6.0_01-fcs
requirescompat-libstdc++-33
.
- If you get
Error: Missing Dependency: python(abi) = 2.4 is needed by package libxml2-python
and/orError: Missing Dependency: python(abi) = 2.4 is needed by package rpm-python
during youryum upgrade
ensure you have done ayum clean all
and check that both thebase
andupdates
repositories are available from your mirror. You will need theupdates
repo for the upgrade to succeed.
Fedora Core 5 -> Fedora Core 6
- After upgrading, you cannot use the DVD ISO loopback mounted as a repository directly (e.g. no
baseurl=file:///mnt/fc6/
) because the repodata files contain URLs of typemedia://
which yum can't handle. You can use the loopback-mounted DVD for the initial upgrade from FC5 -> FC6, just not thereafter. After removing thebaseurl=file:///
option from yourfedora-core.repo
file, remember toyum clean all
.
Fedora Core 4 -> Fedora Core 5
- Before upgrading update your kernel first.
- Make sure you have the latest kernel ABOVE 2.6.14 and uninstall all kernel versions before it, otherwise initscripts and a few other packages will conflict and prevent the ugprade. Use something like the command below
- Install
fedora-release
in the Fedora Core 5 version. Check our mirror sites for a faster download.
- Update your system
- After upgrading, selinux permissions may be incorrect, causing interesting failures such as metacity not starting. As suggested below, to fix this, run
touch /.autorelabel
and reboot
Fedora Core 3 -> Fedora Core 4
- make sure you're on the latest version of yum for FC3:
yum update yum
- Download fedora-release for FC4:
- wget http://yourmirrorhere/pub/fedora/linux/core/4/$yourarch/os/Fedora/RPMS/fedora-release-4-2.noarch.rpm
rpm -Uvh /path/to/fedora-release-4-2.noarch.rpm
- yum update ( This will start the upgradation process to FC4)
- Once you have updated, run:
yum groupinstall "GNOME Desktop Environment"
(change GNOME to KDE if appropriate). That'll get you some new packages that were added in FC4 like Evince and NetworkManager. - Some new groups were added -
yum grouplist
- check out Eclipse and Java Development in particular.
Problems:
- Postgres database in FC4 has a newer incompatible format from the previous versions. Manual dump and restoration is required if you using this database. Look at the postgres documentation for more details on this.
- kernel requires kernel-utils (or vice-versa) run:
yum update kernel reboot yum remove kernel-2.6.11\*FC3\* yum upgrade reboot
- Takes forever and a day and hangs at:
Reading repository metadata in from local files
This means you have too much crap in your rpmdb and it's taking a while to go through it. Check out how many kernels you have installed: rpm -q kernel kernel-smp and remove the old ones you may also try running: rpm --rebuilddb and see if it helps any. I've found that removing old kernels and rebuilding the rpmdb helped this problem.
- x86_64 upgrade requires removal of certain i386 packages before update
yum remove perl.i386 TODO: Add list of bonobo i386 packages to remove here
- Error: Missing Dependency: libpython2.3.so.1.0 is needed by package koffice
koffice was removed from Fedora Core and not moved to extras - so there's no way to complete an upgrade to FC4 without removing it. run:
yum remove koffice
then your update should complete.
- x86_64 systems seems to hang during "Running Transaction Test"
Seems related to Bug 155730 -- Maybe a update to the "rpm-4.3.3-3.0.fc3" (currently in updates-testing) might solve this. Ugly workaround (to be done as root):
: > /var/log/lastlog
- GPG check fails with this message :
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID db42a60e public key not available for <some_package> Retrieving GPG key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora The GPG key at file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora (0x4F2A6FD2) is already installed but is not the correct key for this package. Check that this is the correct key for the "Fedora Core 4 - i386 - Base" repository.
Edit /etc/yum.repos.d/fedora.repo and replace the line
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora
with:
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY
- SELinux gets messed up. I had to redownload the selinux-policy-targeted RPM from my mirror, do a forced uninstall of the old package, clean out the .rpmnew and .rpmsave files then install the new policy. Then I had to run "/sbin/fixfiles relabel" and wait. If I didn't do that, I found I couldn't log in.
- If SELinux does give you problems, it can be disabled on bootup by pressing "a" on the grub bootup menu, then adding "enforcing=off" to the arguments list.
- RPM complains about missing diskspace, but there is a lot free. If you are really sure your diskspace is enough, set
diskspacecheck=0 </code> in <code>/etc/yum.conf</code>. The RPM transaction will need a lot of diskspace temporarily (much more than one might think), so be careful. Don't forget to remove that later after the upgrade. * Yum complains about files conflicting in the GCC package. This system was upgraded from Fedora Core 1. Remove the gcc32 package: <pre> sudo rpm -e gcc32
- Some of your modules don't load after the upgrade. When you investigate modprobe doesn't work as expected. Run depmod:
sudo depmod -ae -F /boot/System.map-[your <code>uname -a</code> kernel version here]
- Yum has been reported to be hanging after upgrading. Updating the pysqlite package might fix it.
