I've been trying to get a connection to work using SSH and private key for authentication. No matter what kind of ssh private key I use (with or without passphrase or different encryption method) I always get the same errors:
Feb 24 13:13:18 guacd[318]: DEBUG: Attempting private key import (WITHOUT passphrase)
Feb 24 13:13:18 guacd[318]: DEBUG: Initial import failed: (null)
Feb 24 13:13:18 guacd[318]: DEBUG: Re-attempting private key import (WITH passphrase)
Feb 24 13:13:53 guacd[318]: ERROR: Auth key import failed: (null)
I believe the issue is related to this: https://issues.apache.org/jira/browse/GUACAMOLE-1540
The suggested solution is to update the guacamole-server docker build to use libssh2 1.9.0-3.
Currently it is using libssh2 1.8.0-2
Can you please update the dockerfile to use the newer version of libssh2?
