Broken intl extension in PHP 7.4 & 8.0 due to ea-libicu-77.1-1.el8.cloudlinux.x86_64 upgrade

Issue

Recently, an update to the ea-libicu package (version 77.1-1.el8.cloudlinux) has caused issues with the php-intl package for PHP versions 7.4 and 8.0. This has resulted in downtime for clients relying on the intl functions in their applications.

Possible error message:

PHP Warning: PHP Startup: Unable to load dynamic library 'intl.so' 
(tried: /opt/cpanel/ea-php74/root/usr/lib64/php/modules/intl.so 
(libicuuc.so.76: cannot open shared object file: No such file or directory),
 /opt/cpanel/ea-php74/root/usr/lib64/php/modules/intl.so.so 
(/opt/cpanel/ea-php74/root/usr/lib64/php/modules/intl.so.so: 
cannot open shared object file: No such file or directory)) in Unknown on line 0

Environment

• CloudLinux
• ea-libicu-77.1-1
• ea-php80-php-intl-8.0.30-8.el8.cloudlinux
• ea-php74-php-intl-7.4.33-13.el8.cloudlinux.2

Solution

The patch versions are already in our stable repositories. To update, please run:

yum clean all && yum makecache
yum update ea-php74-php ea-php80-php

Important note:

Downgrading ea-libicu isn't an option without breaking PHP 8.1+.

Cause

The issue arises because the ea-php74-intl and ea-php80-intl packages were not built against the new ea-libicu version, causing them to attempt to link to the previous version (76), which is no longer available. This has resulted in broken functionality for websites that depend on the intl extension.
