Description

In CloudLinux 8, the alt-php*-pecl-ext packages include the yaml package, which creates package conflicts with the alt-php*-pecl-yaml packages. alt-php*-pecl-ext packages built in July 2024 moved the yaml package to a separate package.

Workaround

1. Access the server's command line as the 'root' user via SSH or " Terminal " in WHM.
2. Remove the alt-php*-pecl-yaml packages.

   rpm -qa |grep alt-php | grep pecl-yaml | while read yamlpkg ; do rpm -e --nodeps $yamlpkg ; done

3. Continue the ELevate process.

   /usr/local/cpanel/scripts/elevate-cpanel --continue
