I updated my system from Ubuntu 23.10 to 24.02. I have setup mandos-client on the machine which encrypts my LUKS drive via a secret received from mandos-server running on another machine.
But after upgrade if I attach a screen to my sever I receive gpg: No Secret Key
and encryption needs to be done manually by enter the passphrase.
The sever is providing the secret. I can see this on server side. On client side the key is also still in /etc/keys/mandos
.
I guess I need to update my initrd image file. Maybe it was reset during upgrade. But how?
The man pages and website does not help: https://www.recompile.se/mandos
