Why won't Yum install the latest version of Perl?

Unix & Linux Asked on December 4, 2021

Why won’t Yum install the latest version of Perl? I see that Perl is at 5.32.0 https://www.perl.org/get.html. My Perl is 5.10.1.

# perl -v
This is perl, v5.10.1

When I try to update, it doesn’t do anything.

# yum update perl
No Packages marked for Update

Here is the info for Perl

# yum info perl.x86_64

That's simply the newest version RedHat/CentOS provides. Bear in mind that CentOS is an enterprise distribution that is designed not to break during the normal lifecycle, so feature updates are pretty rare and bugfixes are often backported from newer versions to older ones.

Note that that perl will not replace /usr/bin/perl, it will install the new version into /opt/rh/....
