[Pkg-auth-maintainers] Bug#1022840: yubikey-agent: keys are not added to the agent

[Markus Grunwald]

Package: yubikey-agent
Version: 0.1.4-2+b3
Severity: important

Dear Maintainer,

When using a YubiKey 5C Nano, ssh keys are not added to the 
yubikey-agent. Instead, these errors occur:

>From ssh -vvvv :
debug1: could not add identity to agent: 
/home/markus/.ssh/id_ed25519_sk (-27)

>From systemctl --user status yubikey-agent:

agent 25: agent: not implemented: "sk-ssh-ed25519 at openssh.com"

I would habe expected that the key is added to ssh agent and I 
don't have to enter the passphrase again.
