Comment:

 This issue has plagued me for a long time, to the extent that I use sshfs
 most of the time instead. If I check my server logs, I can see that
 Cyberduck tries all my ssh keys:

 {{{

 56376 on [REDACTED] port 22

 }}}

 Despite that I did set

 {{{
 Host [REDACTED]
   PreferredAuthentications password
   PubkeyAuthentication no
 }}}

 Command line sftp and sshfs works fine. Let me know if I can provide more
 information to help debugging this. I did try enable debug logging, but it
 didn't seem like it provided much additional information.

 I'm using Cyberduck 7.6.1, but this has been an issue for a long, long
 time.
