91-siduction-entry-key.install: line 43: 10000 - : arithmetic syntax error

Just an ordinary upgrade after 4 weeks. Big crime, NOX, rootfs on btrfs.

Processing triggers for initramfs-tools (0.151) ...
update-initramfs: Generating /boot/initrd.img-7.2.12-1-siduction-amd64

/usr/lib/kernel/install.d/91-siduction-entry-key.install: line 43: 10000 - : arithmetic syntax error: operand expected (
error token is "- ")

In the script

Code Select Expand

91-siduction-entry-key.install
variable entry_path gets set to /boot/siduction-nox/7.2.12-1-siduction-amd64. The pipe

Code Select Expand

grep -o "shot-[0-9@]\+" <<< $entry_path | sed s'!shot-!!'
produces no output, thus variable sn_nr gets assigned the empty string. The following lines

Code Select Expand

if [ "X$sn_nr" = "X@" ]; then
        key="10000"
else
        key=$((10000 - "$sn_nr"))
fi
are not prepared for this, producing the above mentioned error message.

I have worked around this issue by adapting the script. But I keep asking myself if I did something wrong here or if the script is simply buggy.

Thanks for pointing that out.
I'll take a look at the script.
It's probably a bug.

The cause is an incomplete entry in the /etc/kernel/entry-token file.
To help you, I need the following information.
Please show the output of:

ls /usr/lib/modulesand  if only one ESP is used,

tree /efior if an XBOOTLDR partition is also used

Mind that /boot is NOT XBOOTLDR, but ESP. (Cannot recall why it is not as you expected. As far as I remember, this was a clean install with NOX ISO without any extra fiddling.)
