ssh2.exceptions.PublickeyUnverifiedError

[max-l]

I have have an rsa key that works the ssh program running from a shell (ssh -i myKey me@myhost)

When connecting with pssh, I get this exception:

Traceback (most recent call last):
  File "/home/maxou/dev/dry_pipe/venv3.10/lib/python3.10/site-packages/pssh/clients/base/single.py", line 204, in _auth_retry

ssh2.exceptions.PublickeyUnverifiedError

Note1: the same key DO work when using pssh on OTHER hosts. So the problem is only with a specific host.

Note2: ssh -v gives me the same relevant lines, on working hosts as well as on non working hosts :

debug1: Local version string SSH-2.0-OpenSSH_8.9p1 Ubuntu-3
debug1: Remote protocol version 2.0, remote software version OpenSSH_7.4
debug1: compat_banner: match: OpenSSH_7.4 pat OpenSSH_7.4* compat 0x04000006

You seem to have found the wrong project. No mentioned files exist in this project and this project doesn't use ssh2; it uses the ssh command line tool.
