Security Updates

Latest response

Hi,

Think my lack of understanding is a fault here so I'm hoping it can be cleared up here.

We have decided to patch some of servers with security updates only. However, when I type:

% yum update --security

I see no patches returned. Only the following output:

Setting up Update Process
Resolving Dependencies
Limiting packages to security relevant ones
No packages needed for security; 355 packages available

What is this telling me? Is it basically there are no security updates available within our repository? Do I need to subscribe to a separate security channel for example. I've searched on RedHat customer portal and come across the errata web page. Is this the aspect I need to update from to appease our security needs?

Any help and/or advise will be greatly appreciated.

Thanks,
DJC.

From the output you have shown, it looks that way. You can try some other commands if you wish. See my little blog.

Using "yum-plugin-security" we have list the latest security patches.

For Installing "yum-plugin-security

yum install yum-plugin-security

For Listing Security Updates:

yum updateinfo list security

For Installing Security Updates:

yum --security update

For Listing Available Updates:

yum updateinfo list available

Hello While running below command we are getting below issue,

yum updateinfo list security

You can try a yum clean all and then retry your command. Somethings the yum cache contains old info.

Hi Christiaan,

Let me add that in order to clean the cache, sudo rm -r /var/cache/yum has to be executed additionally. :)

Christian
