Interesting ? Don't forget I compiled and installed via make install, so I  had
to manually remove the following entries:

/boot/vmlinuz*KERNEL-VERSION*
/boot/initrd*KERNEL-VERSION*
/boot/System-map*KERNEL-VERSION*
/boot/config-*KERNEL-VERSION*
/lib/modules/*KERNEL-VERSION*/
/var/lib/initramfs/*KERNEL-VERSION*/

Then update the grub configuration:
sudo update-grub2

Then look for any loose ends using 'locate':
locate -b -e *dkms 3.18.2-*

You get the idea. Was definitely not fun :-)

Hmm... should be possible. Never needed to do this before so another
learning experience for me here. I will get back to you on this.

I used to work from home as a remote agent for a call center and they
had a policy
we had to use Windows no exceptions.  I tried to convert them to Linux
and you all
know how that went :-)

Could well be ... but 'locate' shows me this:

aruna at debian:~$ locate Makefile.normal
/usr/src/open-vm-tools-9.4.6/vmci/Makefile.normal
/var/lib/dkms/open-vm-tools/9.4.6/build/vmci/Makefile.normal

Does that help or make any sense ?

Yes sir you most certainly did help.
