Earlier this morning while working on a CentOS Linux development server I received errors when doing anything with the yum package manager. I believe the error started after upgrading the kernel on the server from kernel version 2.6.18-164.15.1.el5 to kernel version 2.6.18-194.3.1.el5. After upgrading the kernel yum would output the same error multiple times as shown in the below output example.
On Linux, ptsname is included with glibc by default since glibc 2.1. You can verify that glibc is installed on CentOS Linux by using the below command.
Verify glibc Is Installed on CentOS Linux:
