(Solved) Errors while installing Kernel 4.13.0-26

[Rademes]

Good evening!
Following this Security notice, I have installed newest Kernel 4.13.0-26, using update manager. However, while installing, I have noticed some error messages:
ERROR (dkms apport): kernel package linux-headers-4.13.0-26-generic is not supported
Error! Bad return status for module build on kernel: 4.13.0-26-generic (x86-64)
Maybe, I have made mistakes while typing, so please look at the screenshots:

Also, while running command dkms status, I have ndiswrapper only for 4.10.0-xx kernels...

Luckily, I have not been installed proprietary drivers so far.
Should I worry about these error messages, and revert back to older kernel?
Can I install newest Intel Microcode update, as suggested in this Security notice?

For the ndiswrapper-dkms, from a recent thread and a somewhat similar problem,
it appears you can safely ignore the error message (it simply won't work with this kernel version):

And yes, you can install intel-microcode safely, no worries there...

OK, so I have removed ndiswrapper, ndiswrapper-dkms and ndiswrapper-utils-1.9, because my desktop does not have wireless adapter.
Then I have removed all 4.10.0-xx kernels. Only newest Kernel 4.13.0-26 has left on my system. I will update Intel Microcode later.
Hope, without ndiswrapper-dkms, there will not be any errors while updating kernels.
