We use Katello/Satellite 6 to manage our repos/pkgs and subscribe our servers to it. In the Katello Web UI it says that glibc-2.12-1.212.el6.x86_64 and glibc-common-2.12-1.212.el6.x86_64 is an applicable update on the system, I'll then click to update and it'll say successful.. however nothing happens and Katello still shows me that it's an applicable update.

If I ssh to the server itself and try and do a yum install glibc-2.12-1.212.el6.x86_64 it says no package found. This is on a CentOS 6.10 box.

We have some other packages such as nscd which rely on the latest glibc as a dependency as well so I'm just super curious why this is happening.

company_repos_centos6_os and base repos definitely have glibc-2.12-1.212.el6.x86_64 in there.

As requested in the comments, my /etc/yum.conf contains a repo that has exclude=glibc-* kernel-* and actually doing a yum update doesn't work.

  • What version of glibc is on the server right now? You can find out with rpm -qa | grep glibc or yum list available | grep glibc. – Nasir Riley Apr 3 '19 at 2:35
  • Hello @NasirRiley! Current version is: glibc-2.12-1.192.el6.x86_64 glibc-common-2.12-1.192.el6.x86_64 – beginner_programmer Apr 3 '19 at 18:02
  • Doing a 'yum install glibc-2.12-1.212.el6.x86_64` says No package glibc-2.12-1.212.el6.x86_64 available. Error: Nothing to do Uploading Enabled Repositories Report – beginner_programmer Apr 3 '19 at 18:05
  • Are the necessary repos enabled on the system? – Nasir Riley Apr 3 '19 at 18:23
  • @NasirRiley They most definitely are. I've checked the repo itself to see if 212 is in there and it is. I'm really stuck at this point :( Does the kernel have to be on the latest version maybe? – beginner_programmer Apr 3 '19 at 20:04

Your last comment reveals your issue.

Remove the exclude line from the repo file and/or /etc/yum.conf, run yum clean all, and try to install glibc again. That line is excluding the package(s) that you need to update.

  • You might want to find out why there’s an exclude on glibc. At this point centos6 is pretty stable and unlikely to change so one should try to keep it up to date. – jsbillings Apr 4 '19 at 2:03
  • Good call. I'll be sure to check before removing that line. Question.. if my yum update is failing due to dependencies of glibc, should I just exclude those as well for now? – beginner_programmer Apr 4 '19 at 17:35
  • @AlexanderDo Remove the exclude line and yum update will work. – Nasir Riley Apr 4 '19 at 18:10
