I am new to CentOS and I am using it because Citrix XenServer is running on it.[root@xen01 shm]# uname -aLinux xen01 2.6.32.43-0.4.1.xs1.8.0.855.170800xen #1 SMP Mon Jul 21 05:12:35 EDT 2014 i686 i686 i386 GNU/Linux[root@xen01 shm]# lsb_release -aLSB Version:    :core-4.0-ia32:core-4.0-noarchDistributor ID: XenServerDescription:    XenServer release 6.2.0-70446c (xenenterprise)Release:    6.2.0-70446cCodename:   xenenterpriseI installed apcupsd package, from http://sourceforge.net/projects/apcupsd/files/rpms%20-%20Stable/3.14.10/apcupsd-3.14.10-1.el5.i386.rpm/downloadBut there was a new version the past year, and seems that RPM wasn't updated to 3.14.12.I found this version however: https://admin.fedoraproject.org/updates/FEDORA-EPEL-2014-4191/apcupsd-3.14.12-1.el6I would like to know what exactly EL5 and EL6 means in term of packages. The latter fails because of dependencies, but am I able to instal EL6 packages?Thanks a lot.
What does EL5 and EL6 means in term of packages?
centos;package management;rpm
EL5 stands for Enterprise Linux 5 (Red Hat Enterprise Linux version or CentOS version) and EL6 accordingly for Enterprise Linux 6.You can find the current release you are running in:cat /etc/redhat-release or cat /etc/centos-releaseDepending on the version your system is running with you are able to install the packages.
