When I run update-grub, I get:
/usr/sbin/grub-mkconfig: 1: /etc/default/grub: . /etc/os-release : not found
/etc/os-release is a valid file though (link to /usr/lib/os-release)/
It's a good thing I kept the old line, because that still works. Is this a bug or did I do something wrong?
GRUB_DEFAULT=0
GRUB_TIMEOUT=10
#GRUB_DISTRIBUTOR=`( . /etc/os-release; echo ${NAME:-Debian} ) 2>/dev/null || echo Debian`
GRUB_DISTRIBUTOR=`( . /etc/os-release && echo ${NAME} )`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""
Three siduction systems updated so far today -- no problems with any packages including grub.
Just checked and my file is different from yours. Not sure why?

What do you get when you run:
. /etc/os-release && echo ${NAME}
Hi @seasons.
Your query is unclear.
Which is your old line?
The commented-out line contains the better function.
With
# ls -l /etc/os-ralease
you can recognize whether it is a file or a link, or a broken link.
For both lines with "GRUB_DISTRIBUTOR", grub terminates with an error message if /etc/os-ralease is not found. Only the error message differs.
Therefore: Check the files or the link. (/etc/os-ralease and /usr/lib/os-release)

GRUB_DISTRIBUTOR=`( . /etc/os-release; echo ${NAME:-Debian} ) 2>/dev/null || echo Debian`The new line was what I copied when apt prompted me to keep the old version or install the new one (because I increased the timeout).

Yes, /etc/os-release is a valid file (link to /usr/lib/os-release, which is also a valid file).

I don't know why either, but I just changed it to:
GRUB_DISTRIBUTOR="Debian"Good enough for me. It seems like this was what the old command was effectively doing anyway since the /etc/os-release thing was failing.
Thanks to all who responded.
