I'm having a problem installing kamailio 5.4 using the following guide https://kamailio.org/docs/tutorials/5.4.x/kamailio-install-guide-git/
I have a debian 10.7 machine where I install default-mysql-server package for the database. After that I follow the install guide and everything goes smoothly until I have to install the init.d scripts. 
1. I do "cd /usr/local/src/kamailio-5.4/kamailio'
2. I do "make install-initd-debian"

Then make fails with the following error
"
root@kamServ:/usr/local/src/kamailio-5.4/kamailio# make install-initd-debian
make -C src/ install-initd-debian
make[1]: Entering directory '/usr/local/src/kamailio-5.4/kamailio/src'

make[1]: Leaving directory '/usr/local/src/kamailio-5.4/kamailio/src'

Am I doing something wrong? Possibly in the wrong directory? If you need any more information please don't hesitate to ask.

Sincerely,
Matthew Sherwood
