4.3. Command Line Version


If you are not running X, you can still run the Red Hat Update Agent from a virtual console or remote terminal. If you are running X but want to use the command line version, you can force it not to display the graphical interface with the following command:
up2date --nox
The command line version of the Red Hat Update Agent allows you to perform advanced functions or to perform actions with little or no interaction. For example, the following command updates your system with no interaction. It downloads the newer packages and installs them if you configured it to do so.
up2date -u
The command line version of the Red Hat Update Agent accepts the following arguments:
Table 4.2. Update Agent Command Line Arguments

4.3.1. Installing the Red Hat GPG key

The first time you run the graphical version of the Red Hat Update Agent, it prompts you to install the Red Hat GPG key. This key is required to authenticate the packages downloaded from Red Hat Network. If you run the command line version the first time you start Red Hat Update Agent, you must install the Red Hat GPG key manually. If you do not have it installed, you will see the following message:
Your GPG keyring does not contain the Red Hat, Inc. public key.
Without it, you will be unable to verify that packages Update Agent downloads
are securely signed by Red Hat.

Note

GPG keys must be installed for each user. To install the key to use with Red Hat Network, import the key while logged in as root.
The method for installing the key varies depending on your version of RPM. Starting with version 4.1, which shipped with Red Hat Enterprise Linux 3, you may use RPM to import GPG keys. Issue the following command at a shell prompt as root:
 rpm --import /usr/share/doc/rpm-4.1/RPM-GPG-KEY 
For older versions of RPM, such as the one that came with Red Hat Enterprise Linux 2.1, use the gpg command (as root):
 /usr/bin/gpg --import /usr/share/rhn/RPM-GPG-KEY 
To download the Red Hat GPG key first, you may obtain it from https://www.redhat.com/security/team/key.html . Here's an example:
Type bits/keyID Date User ID
pub  1024D/650D5882 2001-11-21 Red Hat, Inc. (Security Response Team)

Save the text file and import it into your keyring using the method applicable to your version of RPM.

4.3.2. Manual Package Installation

If you chose to download, but not install, the software updates with the Red Hat Update Agent or from the RHN website, you must install them manually using RPM.
To install them, change to the directory that contains the downloaded packages. The default directory is /var/spool/up2date. Type the command rpm -Uvh *.rpm. When the packages finish installing, you can delete them if you wish. You do not need them anymore.
After installing the packages, you must update your System Profile so that you are not prompted to download them again. Refer to Section 4.3.3, “Synchronizing Your System Profile” for details.

4.3.3. Synchronizing Your System Profile

If you configured the Red Hat Update Agent to install the latest packages, the System Profile stored by Red Hat Network is updated after the packages are installed. However, if you only download the latest RPM packages using the Red Hat Update Agent, download the RPM packages from the website, or upgrade/install/remove RPM packages yourself, your System Profile is not updated automatically. You must send your updated System Profile to the RHN Servers.
To synchronize the RPM package list on your local Red Hat Enterprise Linux 5.3 system and on Red Hat Network, run the command:
rhn-profile-sync
After running this command, your RHN System Profile reflects the latest software versions installed on your system.
For Red Hat Enterprise Linux 4 systems, use the following command to update the package list, run the command:
up2date -p

4.3.4. Log File

The Red Hat Update Agent keeps a log of all the actions that it performs on your system in the file /var/log/up2date. It uses the standard rotating log method. Thus, older logs are in /var/log/up2date.1, /var/log/up2date.2, and /var/log/up2date.3. The log files store actions performed by the Red Hat Update Agent such as when your RPM database is opened, when it connects to Red Hat Network to retrieve information from your System Profile, which packages are downloaded, which packages are installed using the Red Hat Update Agent, and which packages are deleted from your system after installation. If you choose to install and delete packages yourself, it is not logged in this file. Red Hat Network recommends that you keep a log of actions not performed with the Red Hat Update Agent.
