Edit 1:
Running Ubuntu 18.04 here. I'm trying to set /sys/module/libata/parameters/allow_tpm, but to no avail.
modinfo libata tells me:
modinfo: ERROR: Module libata not found.
This is after running apt-get install --reinstall linux-headers-$(uname -r) followed by apt update && apt upgrade as well as a nice reboot.
How I got to this point
I've tried editing /sys/module/libata/parameters/allow_tpm as root, but to no avail.
After doing chmod 644 on the file and running echo 1 > /sys/module/libata/parameters/allow_tpm I get:
-bash: echo: write error: Input/output error
I've also tried adding this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash libata.allow_tpm=1"
to /etc/default/grub, followed by update-grub (as recommended here: https://stackoverflow.com/questions/20485142/ata-trusted-commands-how-to-set-libata-allow-tpm) but that doesn't help.
Not even appending libata.allow_tpm=1 to /etc/sysctl.conf has any effect.
What I really want to do
I want to be able to run sedutil. But running sedutil-cli --scan tells me that
The Kernel flag libata.allow_tpm is not set correctly
What do I do?
