How to enroll keys for secure boot?

@thephatlee that worked, thanks!

In summary, this is what I had to do to fix my issue.

  1. Install sbctl - they have a repo for it, but I manually compiled it since it does not work in toolbox and I didn’t want to install it on my host (Fedora Silverblue). Thankfully it was very easy. In toolbox, I ran these commands to compile it.
sudo dnf install golang asciidoc
mkdir build && cd build
git clone https://github.com/foxboron/sbctl.git
cd sbctl
make

From here, I left the toolbox and could run ./sbctl to run the program.

  1. Run sudo ./sbctl enroll-keys --microsoft
  2. Reboot
