I've tried asking this questions in numerous other places and so far
I've had no response, so I'm hoping someone here will be able to help.
I rebooted my server last week and when I tried to remove old kernels it
was stopping when trying to update grub. I ran update-grub2 on its own
and I get:
Generating grub configuration file ...
