Trouble with insserv after my last system update

My problem : So I noticed an error message during my last update Capture du 2021-01-13 22-12-32
I looked into /etc/init.d/ but honestly this start to be above my actual knowledge (the header of ntp,ssh and sysstat) and it is the same
Capture du 2021-01-13 22-27-50

So I tried to fix it with insserv -vd /etc/init.d/ntp

But mountkernfs , checkroot , mountdevsubfs and bootmisc dont exist in my system (/etc/init.d/) and I dont know what they are about
