depmod: ERROR: could not open directory /lib/modules/4.9.124-xxxx-std-ipv6-64: No such file or directory
depmod: FATAL: could not search modules: No such file or directory

Fix this issue with the following steps:

1. Reinstall KernelCare extension in Plesk > Extensions > KernelCare
   
   
2. Rerun Plesk update from Plesk > Tools and Settings > Updates and Upgrades or via a command-line interface:
   
   # plesk installer --select-release-current --reinstall-patch --upgrade-installed-components

Hi IgorG,
Thank you for your support.
I can't uninstall the KernelCare extension.
When i try this command # plesk installer --select-release-current --reinstall-patch --upgrade-installed-components
I get this Error : BUSY: Update operation was locked by another update process. exit status 1
So i try to kill the process first on the command line (SSH). Then i try to reinstall all components.
But, the problem still exists..
How can i uninstall this KernelCare extension ?

I can't uninstall the KernelCare extension.

What do you mean? Click on the extension icon, then to More button and Remove.
