Hi @mihail_karpych,
Not sure what the issue might be. Start by making sure:
# rpm -qf /usr/sbin/ldconfig
returns correctly with the glibc package and version.
If it does, then perhaps try to do:
# yum update glibc
manually to see why it is failing and perhaps report to CentOS, as you can see, the complaint is about updating the glibc package, not a Kalturian one.
