Bug#969330: libpam-ssh-agent-auth: Authentication fails a random number of times before succeeding when ED25519 keys are used.

[Chris Boot]

Control: reassign -1 gnupg2

Hi all,
This bug actually appears to be in GnuPG itself, not 
libpam-ssh-agent-auth. Please see my comments at the end of 
https://github.com/jbeverly/pam_ssh_agent_auth/issues/28.

The bug is fixed in GnuPG 2.3.4 and 2.2.33 with the following changelog 
entry for both:

  * scd: Support longer data for ssh-agent authentication with openpgp
    cards.  [T5682]

This corresponds to the following GnuPG bug:

https://dev.gnupg.org/T5682

Please update GnuPG to 2.2.33 or 2.3.4.

Thanks,
Chris
