yum update giving errors

[fazulur.r]

Dear CentOS team,

I am getting errors while running yum update.

Here is the error:

"Error: Cannot retrieve repository metadata (repomd.xml) for repository: home_fengshuo_zeromq. Please verify its path and try again"

Could you please help me to resolve this.

Thanks & Regards

home_fengshuo_zeromq is not a CentOS supplied repo. You need to contact whoever maintains that to find out its current status. In the meantime you can disable that repo by editing the file in /etc/yum.repos.d/ that defines it and setting 'enabled=0' or using yum --disablerepo=home_fengshuo_zeromq ...

Dear Dr.TrevorH,

Thanks a lot for your quick response.

As I am new to this, I don't have any idea about this error.
We are using CentOS release 6.3 (Final). Somehow yum got disturbed today while installing R package.

I tried disabling "home_fengshuo_zeromq" repo using

command : yum update --disablerepo=home_fengshuo_zeromq

Now it's giving below error

Could you please help me to resolve this.

No, really, just no. Do not run 6.3. That came out almost exactly 5 years ago and is now riddled with high severity security vulnerabilities that are patched in later versions. You need to get current which is 6.9 plus another 6 months or so of patches. To do that you need to run yum update

Do not use rpmforge. It has been abandoned for over 4 years and contains many packages with unfixed security problems that will never be fixed. Find alternative sources for any packages you have installed from rpmforge.

In addition, that says you're using the CentOS 5 version of rpmforge and you claim to be running 6.3 so not only do you have an abandoned and dangerous repo installed, you have the wrong version of it. Do not install CentOS 5 packages on CentOS 6.

Disable that repo too. Better yet, identify the packages you use from it (probably rpm -qa | grep ".rf" will list those or use the keychecker utility from EPEL to list packages by GPG signing key and identify them that way. Find a better repo for those packages then remove rpmforge altogether.

Dear Dr.TrevorH,

Thanks for your suggestions. I will try to fix that and let you know the update.
