[Bug]: kernelpkg.upgrade doesn't work with trixie

[asbates-byte]

What happened?

Running salt -C 'G@kernel:Linux and I@upgrade:1' kernelpkg.upgrade reboot=True at_time=2 results in the following error.
This is on a Debian13 machine, but the drop down below doesn't offer that as an option although I am sure it is supported.

The minion function caused an exception: Traceback (most recent call last):
