Convert RHEL 6.x to CentOS 6.x

[klinux]

Hello,

I followed instructions on this site: https://www.pickysysadmin.ca/2014/07/15 ... entos-6-x/

The last step yum upgrade or yum update is showing dependency errors:

 You could try using --skip-broken to work around the problem
** Found 2 pre-existing rpmdb problem(s), 'yum check' output follows:

Your installed system appears to be 6.6 judging by the glibc version involved but the CentOS repos you're pointing to appear to be for 6.1. Neither 6.1 nor 6.6 is a supported version - only 6.9 gets fixes and is the only CentOS 6 version that is supported.

You need at the very least to point your CentOS repos to 6.6 to match your currently installed system. Once that's done you need to update to 6.9.

Hi Trevor,

The RPMs I downloaded from: http://mirror.centos.org/centos/6/os/x86_64/Packages/

Code: Select all

[root@server01]# cd /temp/centos
[root@server01 centos]# ls -la
total 1184
drwxr-xr-x. 2 root root    4096 Mar 22 09:13 .

-rw-r--r--. 1 root root   33524 Mar 23  2017 yum-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm

I did "yum clean all" then reinstalled the rpms without centos-indexhtml-6-2.el6.centos.noarch.rpm and its updating now.

thanks you

Rather than following an unknown page on the internet, I'd be using the one on the CentOS wiki - https://wiki.centos.org/HowTos/MigrationGuide - though even that should be treated with caution and you get to keep all the pieces if it breaks!
