Hi @Maddan. I see on one of my test systems here that krb5-libs also has an update available(1.14.1-27). So not sure why it’s complaining about 1.13.2. Do you have any custom yum repos enabled?
update from the UI fails because it’s also running yum update behind the scenes and fails.
Have you considered just downloading 3.8.16 ISO, do a fresh install and import your data back? I know this is not ideal, but is a simpler option compared to troubleshooting and cleaning up yum if you are not a power Linux or CentOS user.
