Mandos client on ubuntu 20.04 failed because cryptroot file is missing

[Florian Coulmier]

Hi all,

We are trying to setup mandos on an Ubuntu 20.04. We are running into trouble because mandos seems not to start at boot.

Our investigation lead us to file /usr/share/initramfs-tools/hooks/cryptroot which has changed. This file does not generate a file /conf/conf.d/cryptroot in the initrd image.

This makes script /scripts/init-premount/mandos (from initrd image) fail as it requires file /conf/conf.d/cryptroot (line 54).

We tried to identify how to fix that, but we only came with a workaround: generate file cryptroot from file /etc/crypttab.

Do you see another solution?
We use mandos-client v1.7.19-1 from official ubuntu repo.

Thanks
