For some reason you have a thoroughly obsolete version of grub-mkconfig.
Your report said that you have grub-common 2.02~beta3-1, but the above
is clearly from 2.02~beta2-17.  I suspect that you have a local
diversion of /usr/sbin/grub-mkconfig.  Try "dpkg-divert --listpackage
/usr/sbin/grub-mkconfig"?
