I am trying to run UC20 with FDE on amd64. Booting seems to work first, TPM is found, but install fails then with:
taskrunner.go: 271: [change 2 "Setup system for run mode" task] failed: cannot make system runnable: cannot seal the encryption keys: cannot add EFI secure boot policy profile: cannot compute secure boot policy profile: no bootable paths with current EFI signature database.
Any idea how to solve/debug the issue? Without FDE, everything works as expected.
I reported this as possible bug already at https://github.com/snapcore/secboot/issues/172 but got no t yet any answer.
