When editing a DNS records via the cPanel Zone Editor on Ubuntu servers, the following error can be shown and prevent the record from being modified:
The system failed to send 17.54 KB to the process that is running the command “/usr/sbin/named-checkzone.
The issue is caused after the Ubuntu bind9-utils package is upgraded or reinstalled. This results in the named-checkzone binary being removed from the /usr/sbin directory, thus, causing the Zone Editor error.
We’ve opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-45739. Follow this article to receive an email notification when a solution is published in the product.
Workaround
Create a symbolic link to the /usr/sbin directory:
ln -s /usr/bin/named-checkzone /usr/sbin/
