Comparing the artifacts between a failed and successful log, the relevant difference appears to be that cryptsetup-initramfs is only installed in the failed log. These errors also appear during the setup phase when package installation causes the initramfs for the host to be updated:

So this seems like a host configuration issue. Is there a LP project for those for which we could add a task?
