I notice that there are no docs for yum and redhat 8.0. It is possible I
may have missed them but I am looking at
http://www.fedoralegacy.org/docs/ in particular. I have copied and
pasted from the redhat 7.x instructions and changed things where
necessary. Please take a look and see what needs to be fixed before it
can be put up. I have omitted documention on how to use yum 1.x with
redhat 8.0 as I don't recommend it. Please add it if you think it is
Using yum to keep Red Hat Linux 8.0 up to date
/yum/ (*Y*ell dog *U*pdater, *M*odified) is an automated package
management program which may be used to install, remove, and update
packages on an RPM based system. It will help you to keep your system up
to date and is used by Fedora Core, the successor to Red Hat Linux.
Step 1: Preliminaries
Linux prevents ordinary users from installing, removing, or modifying
system software, libraries, and important configuration information. So
you must have root access to proceed. You may either login as the root
user, or use the /su/ (or /sudo/) commands to become the root user on
*Note:* Be careful when running as root! Be sure to logout of the root
account as soon as you are done. Running as root is dangerous, and
should only be used when needed. Typos or mistakes can destroy your
system or your data, so it is important that you be careful when running
When you are running as root, your prompt will be changed to the *#*
character. In the command examples below, we include this prompt,
however you should not type the *#* character when entering a command
Step 1: Updating yum and rpm
The one complication with configuring yum to work with red hat 8.0 is
that you have to have the correct yum version to go with your rpm
version. The official chart can be found at
http://linux.duke.edu/projects/yum/download.ptml. However, for our
purposes we simply recommend updating both to the latest reasonably bug
Step 2: Configuring yum.conf
Yum uses a file called yum.conf that can be found in the /etc/ directory
to decide where to download updates from. This file needs to be
configured to work with fedora legacy. The simplest method is to create
such a file containing the following:
# See the yum.conf(5) man page for information the syntax of this file,
# including failover setup.
# Please use nearby mirrors! For a an up to date list of Fedora Legacy
name=Red Hat Linux $releasever ($basearch)
name=Red Hat Linux $releasever ($basearch) updates
name=Fedora Linux / stable for Red Hat Linux $releasever ($basearch)
Step 2.1: Optionally add mirror sites
yum will be installed so as to use download.fedora.us as the source of
updates. You may want to configure it to use additional mirror sites
which are closer to you, faster, or meet your security policy. yum
supports automatic fail-over when one or more servers are unavailable,
so it is advantageous to use multiple mirror sites to take advantage of
this fail-over support. yum will use the sites in the order presented in
the /baseurl/ parameters of your configuration file, so you should order
them so that the most desirable sites will be tried first before your
Again, please note that this step is optional, and it is up to you to
decide if you wish to implement it.
You can find a list of current Fedora Legacy mirrors at
You will need to manually edit the file /etc/yum.conf to set the mirror
site(s) should you chose to do so.
Step 2.2: Add the GPG (security) keys
All Fedora Legacy packages are signed with GPG keys. All packages should
be verified using these keys. See
http://www.fedoralegacy.org/about/security.php for more information.
In order properly to verify the packages, you need to add the
appropriate GPG keys to your root user's keyring. To import the keys,
use the following command as the root user:
rpm --import http://www.fedoralegacy.org/FEDORA-LEGACY-GPG-KEY
Step 3: Update your system
Once you have installed the yum package, you should run the following
command as the root user on your system to update your system:
# yum update
This will create a current package list for your system, download the
updates for all packages which require updating (and any dependencies
for those packages), and install them on your system.
Before you do that you may wish to run
# yum check-update
which will show you all the packages yum thinks need to be updated
*Warning:* This may take some time on your first use of yum, depending
on how up to date your system is and the speed of your internet
connection! Yum is not known for its speed but once you have completed
the first update the subsequent ones will be much faster.
Step 4: Decide if you want automatic updates
yum has the ability to automatically apply (download/verify/install) all
updates to your system, but this feature is disabled by default. If you
want to enable that functionality, please enter the following command as
the root user on your system:
# chkconfig yum on
# service yum start
After that, yum will update your system through the cron job
/etc/cron.daily/yum.cron, which will run every night (or later through
anacron, if your system isn't running all the time).
Step 5: Subscribe to fedora-legacy-announce
You may subscribe to the fedora-legacy-announce
list to be informed by e-mail when new updates become available. This
step is optional, but highly recommended.
Step 6: Please help us with our service!
The Fedora Legacy project is always in the need of helping hands. Please
check the Participate <http://fedoralegacy.org/participate/> section of
our website to see what you can do to help us. As we're a community
project, our success will heavily depend on helping hands – possibly you!
If you find a problem with an update published by The Fedora Legacy
Project, or in The Fedora Legacy Project documentation, please let us know!
Step 7: Optionally learn additional features of yum
Below is a summary of some of the more advanced features of yum for
those who wish to know more. You do not need to know these commands to
keep your system updated; they are simply provided for those who want to
learn more about using yum to its fullest.
List all available software.
See if there are updated packages available.
Update all installed packages that have a newer version available.
yum install /<packagename>/
Install specific package(s) (and its dependencies, if missing any).
yum search /<word>/
Search all known packages entries (descriptions etc) for /<word>/.
yum info /<packagename>/
Show basic information about a package.
