When doing the precheck on my CentOS 7 with WHM and Cpanel for the Almalinux Upgrade I get the following blocking error : * 2023-08-19 17:32:54 [WARN] Unknown error while checking blockers: STDERR: Can't exec "/bin/bash": Permission denied at /usr/local/cpanel/Cpanel/SafeRun/Object.pm line 505. exec(/bin/bash) failed: Permission denied at /usr/local/cpanel/Cpanel/SafeRun/Object.pm line 505. exec(/bin/bash) failed: Permission denied at /usr/local/cpanel/Cpanel/SafeRun/Object.pm line 505.

  Hey there! This seems more like an issue with Bash itself. Can you confirm that /bin/bash exists and has 755 permissions, and that you were running the ELevate script as root? Are you able to run /bin/bash manually when you're logged in?

  /bin/bash exists and has the 755 permissions. Script was running as root. I can execute bash scripts without a problem. Tested on a simple script. Everything Bash works. If i look at the script itselve and the errorline on line 505 : exec( $OPTS{'program'}, @$args_ar ) or die "$exec_failed_message $!"; have no idea where to look..
