Secure boot was enabled and TPM cleared.

But in addition, I had to disable Absolute.

Thanks for pinting this out.

With this, I finally got FDE.

But this has still a draewack: is uses the entire disk. No way to dual boot.

I tried to check the autoinstall-user-data which is created by subiquity. But
there ar no traces of the TMP install method.

Do you have any pointers on how to trigger the TPM method using autonstall?

PS: the installer hould offer to record the recovery key somehow.
