Tests started failing because of the following error:

E: Repository 'https://ppa.launchpadcontent.net/ondrej/php/ubuntu noble InRelease' changed its 'Label' value from '***** The main PPA for supported PHP versions with many PECL extensions *****' to 'PPA for PHP'

Error: Process completed with exit code 100.

The failure is occurring because the ondrej/php PPA repository has changed its Label value, which caused an issue during the package list update step in the workflow.

Solutions found:
1. Add an apt-get flag to ignore the label change warning (sudo apt-get update --allow-releaseinfo-change).
2. Use "sudo apt update && sudo apt full-upgrade -y" instead of just "sudo apt-get".
