I have updated my kernel package to the latest version last week, and today I ran `sudo apt autoremove` to remove the older kernel version (version 4.10.0-20). However during the removal process, it complained that the headers for kernel 4.10.0-20-generic cannot be found (which is the package I removed) with the following error message (The error messaged appeared twice):
> Error! Your kernel headers for kernel 4.10.0-20-generic cannot be found.
> Please install the linux-headers-4.10.0-20-generic package,
> or use the --kernelsourcedir option to tell DKMS where it's located
I do however think the removal process was successful.
