Building dkms module problems

2018 got errors adding module to kernel 4.17.2-041702-lowlatency

Package linux-headers-4.17.2-041702-lowlatency is not available, but is referred to by another package.

 * dkms: running auto installation service for kernel 4.17.2-041702-lowlatency                                         Error! Your kernel headers for kernel 4.17.2-041702-lowlatency cannot be found.

Resolution

Looking at
```
$ ls -l /lib/modules/4.17.2-041702-lowlatency/
```
missing symbolic link build -> /usr/src/linux-headers-4.17.2-041702/

Add

ln -s /usr/src/linux-headers-4.17.2-041702/ /lib/modules/4.17.2-041702-lowlatency/build

DID NOT WORK !
