As part of our Server Management Services, we assist our customers with several similar queries.

Cagefs can’t find binaries

Typically, errors might look as shown below:

Can't exec "/usr/sbin/sendmail": No such file or directory
su: failed to execute /bin/bash: No such file or directory
cagefs_enter_user: /bin/bash: No such file or directory

One of the cause for this issue is a broken cpanel-wrap package.

Today, let us see the steps followed by our Support Techs to resolve it.

Run the check cPanel rpm script to verify and fix if you are impacted by this issue.

/usr/local/cpanel/scripts/check_cpanel_rpms --fix

If the script detected an issue with the cpanel-wrap package and reinstalled the package, we need to rebuild CageFS.

How to rebuild Cagefs?
