You want to read the error message and act on it by creating the /etc/kernel/cmdline file with your needed kernel command-line.

[Pablo Hörtner (redtux2000)]

This is a bug in sicherboot. Unfortunately, it still exists with version 0.1.5 on Ubuntu "hirsute" 21.04. Creating a symlink seems to work fine, so this might be added to the sicherboot postinst.
ln -s /proc/cmdline /etc/kernel/cmdline

(uname -r: 5.11.0-16-generic)

[Wladimir Mutel (mwg)]

is this package still maintained ? it look like abandoned by its author for 6+ years.
so why it is still present in Ubuntu ? it is useless without reviewing all its scripts and hooks.
I still have yet to figure out why it does not add initrd lines into loader entries.

[Julian Andres Klode (juliank)]

My comment in #3 still stands. And no symlinking /proc/cmdline is not entirely correct it contains additional data injected at boot time like BOOT_IMAGE, hence create the file with the content you care about.

Wladimir, we have removed it, it's not shipped past 22.04. It's also not supported at all. And if you don't understand why it doesn't add initrd lines you missed the main point of the package, it sets up UKIs as they are now called and signs everything with a local key such that you can FDE everything except the ESP and have a verified boot path because the initrd is part of the UKI and hence signed and verified.
